When the villainous Mr. Wink and Mr. Fibb extend the adult swimtime to extreme lengths at the neighborhood pool, the Kids Next Door plan to strike back with a vengeance.The episode starts with the operatives of Sector V each being called by Numbuh 1 to the meeting room of the treehouse. Numbuh 1 explains that adults have extended their swimming hours at the local pool so that kids have no time at all, and that they are going to put a stop to this. Upon arriving at the pool and realizing that they have no specific plan of action, the KND decide to simply jump into the pool. The lifeguards, Mr. Wink and Mr. Fibb, see them and activate an electric fence which rises around the pool, shocking them.

They tell the children that it is currently adult swim, but they are welcome to play in the "kiddie pool", which turns out to be an extremely small inflatable pool. The rest of Sector V don't seem to mind this much, while Numbuh 1 refuses to put up with it and yells out, for the first time ever, "Kids Next Door, Battle Stations!"

The five members then spring into action, summoning the Kid-a-Pult, and launching Numbuh 2 over the fence, hitting the lifeguard chair and knocking Wink and Fibb into the pool.

The kids are then free to play in the pool, until Mr. Wink and Fibb arise in their lifeguard chair, which turns into a robotic, laser-firing walker. As the super chair looms over the Kids Next Door, Numbuh 1 suggests they go back to the Kid-a-Pult...

...Which is then immediately destroyed by the super chair. Numbuh 1 then notices that Numbuh 3 is missing, and the team tells him that she went to get snacks. Numbuh 3 then returns with snacks just as the chair is about to destroy them, giving snacks to everyone except Numbuh 1, including the villains, who leave their chair to eat ice cream.

Numbuh 1, infuriated, starts yelling at Numbuh 3 for giving treats to the bad guys when he notices that the super chair has been abandoned. He hijacks the chair and tries to get rid of Mr. Wink and Mr. Fibb, but instead accidentally activates a drilling device that drills a hole in the pool and drains it. This angers everyone, and Numbuh 1 then nervously says, "So, who's going to the kiddie pool?"

Expanded Acronym: New Orders - Pulverize Opposition Without Utilizing Hamsters
The hamsters that power Sector V's weapons go on vacation. Meanwhile, the DCFDTL look for villains to attack Sector V, so they send an old lady named Gramma Stuffum, who is fixated on fattening kids, to Sector V's powerless HQ. The episode begins with the Parent Teacher Organization of Eradicating Youngsters attacking the Sector V Treehouse and being defeated by the KND's various 2x4 weaponry. After the fight, Numbuh 1 asks Numbuh 2 about the ineffective device he used during the battle, and, Numbuh 2 tells him that it is a "rubber band food flinger". Numbuh 1 then scolds him for failing to make better use of their highly advanced resources, showing the team the treehouse's central power core, which contains thousands of Hamsters running around in wheels to power the treehouse and is stated to be the largest power source in the world. Suddenly, the hamsters stop running and scurry out of the treehouse wearing sombreros. Numbuh 3 openly claims responsibility for this, saying that the hamsters deserve a vacation for all their hard work. This causes the treehouse's power to instantly go out. Meanwhile, in the Delightful Mansion From Down The Lane, the Delightful Children are holding job applications for villains seeking to defeat the Kids Next Door. After the Toilenator is rejected and launched out of the house, Gramma Stuffum suddenly barges into the room, wanting to fatten up the Delightful Children with her disgusting food. They tell her that they have just eaten, and that if they eat all her food, there won't be any left for "those poor, starving Kids Next Door", directing her to the location of the treehouse.

Back at the treehouse, Numbuh 1 panics at their situation, which leaves them vulnerable to attack. Numbuh 5 asks what's the worst that could happen, which is immediately followed by Gramma Stuffum crashing through the wall behind her ("That could happen."). She sends her army of living food at the children, and the gluttonous Numbuh 2 eats the food that is sent at him while the others attempt to fight it by normal means, which proves ineffective. His enormous appetite alarms Gramma Stuffum's companions, Liver and Onions, and they push him into the basement to get rid of him. The food continues to feed itself to the remaining kids until they are so fat that they are unable to move. As Gramma Stuffum proclaims victory, she realizes that there are only 4 children in the room, and that one is missing. Numbuh 2 then returns to the room, wearing an improvised commando outfit, and continues to eat all the food that is sent his way. Eventually, however, he is unable to eat anymore and falls to the floor. Gramma Stuffum then orders the desert to be served. The liver and onions order the desert foods to attack, only to look over and see that they have been eaten by the hamsters, who are back from vacation. The hamsters then proceed to eat the remainder of the food army, and Gramma Stuffum, along with the liver and onions, are launched out of the treehouse by the "rubber band food flinger". Gramma Stuffum lands in the Delightful Mansion, where she again sees the Delightful Children and attacks them with her food.

Expanded Acronym: Tooth Extracting Enemy Terrorizes Headquarters
Numbuh 3's teeth are cleaned by a dental-obsessive villain.It starts with Numbuh 3 walking down the street eating candy. During this, her hideous teeth is revealed. When she takes a wrong turn, near a dentist place, the sun suddenly becomes a moon and a light is turned on followed by a evil laughter. Kuki turns around and sees the shadow of a stalker and Kuki screams while the stalker grabs her. The candy she carries is spilled. Kuki comes out with a red toothbrush and discovers her teeth are shining extremely brightly. She screams one more time, louder and Knightbrace with a red toothbrush, is seen on the roof and laughs, maniacally. He jumps from roof to roof and disappears. The Sector V team is waiting for Numbuh 3 to come back from the candy store. After the impatient kids scold Kuki they discover that when Kuki shows her teeth, the team goes into shock with a few gasps. Numbuh 1 claims that his teeth should look like the rest of the team's and it is discovered that the entire group (except Numbuh 1) has horrible teeth. Numbuh 5 suggests they go get some candy for Kuki's teeth and Numbuh 1 agrees saying, "To the Candy Store!"

The team, using Kuki's teeth as a flashlight, walk to the candy store. Numbuh 1 tells Kuki to look ahead and a dentist appears in front of the kids and offers a complimentary check-up. The doctor shows the kids to the door and the team ignores the dentist and walks away. Numbuh 4 even calls the dentist a freak. Next to the dentist is the candy store where the team discovers that the candy store is closed. Numbuh 2 humorously says, "Closed! But its only midnight!" As the team leaves, the door suddenly opens and the candy man tells the kids to come back. The candyman, Mr. Jelly, lets the kids in with a friendly wave from Numbuh 3. The kids than stuff themselves with candy from barrels using bags. Numbuh 2 asks if Mr. Jelly has any taffy and Mr. Jelly nervously says that they're fresh out. Mr. Jelly sends the kids away with Sector V smiling and walking down the dark aisle. Numbuh 4 and the rest talk about Mr. Teeth (the dentist) and demonstrate how they'd fight off the dentist. Numbuh 4 eventually stops talking to the kids about happiness and the rest of the team doesn't bother to look back. The team goes back to the treehouse where they find Numbuh 4 with giant braces, sitting on a chair mumbling and trying to talk. Numbuh 5 calls this being bracified. Numbuh 1 discovers a tag with a purple tooth that threatens to brush after meals or snacks, or else. It also says Signed, Knightbrace.

Numbuh 2 asks what's a knightbrace. Numbuh 5 claims it has to be the dentist while Numbuh 4 is trying to say, Mr Jelly. Numbuh 1 says that they shouldn't jump to conclusions. Numbuh 1 makes a plan to lure the enemy and tells Numbuh 2 to get more candy. Suddenly, Numbuh 1 discovers Numbuh 2, and 5 are gone and notices the treehouse door is opened with a few leaves blowing in. Numbuh 1 comes out and looks around finding Numbuh 2 and 5 tied together by a web of braces and talking. Numbuh 1 decides that Dr. Sigmund Teeth is behind this all.

Sector V goes to the alley where Numbuh 3 was attacked and hide while they wait for Knightbrace to attack a fake Nigel puppet surrounded by candy. Knightbrace comes and scrubs Numbuh 1 rapidly. Numbuh 1 comes from a garbage can and calls the signal. Numbuh 3 shines her light at Knightbrace and the team comes to battle him. Numbuh 1 is hit with a toothbrush meaning that the entire team has been attacked. Knightbrace uses his braces to swing at Numbuhs 5 and 2 which breaks the floss between them. Knightbrace than uses a giant red toothbrush at a singing Numbuh 3. Knightbrace misses Numbuh 3 who dances away. Kuki than shines her teeth at Knightbrace to his annoyance and causes him to use a mirror stunning Numbuh 3. The rest of the team goes after Knightbrace who jumps into a window. The team slowly searches for Knightbrace in Mr. Teeth's office. Knightbrace suddenly comes below and attacks Numbuh 1. Numbuh 4 uses his braces to hurt Knightbrace's foot. Numbuh 3 than shines her teeth at Knightbrace. Numbuhs 2 and 5 come over tying their floss together and knock Knightbrace down. Suddenly, the door opens and the team discovers Dr. Teeth isn't behind Knightbrace but Mr. Jelly! Knightbrace claims that he was kicked out of dental school for putting braces on babies. Mr. Jelly had no choice but to work in his family's candy shop. So he became Knightbrace. Knightbrace suddenly jumps on Mr. Teeth's chair and uses it as a weapon. Mr. Teeth tries to convince Knightbrace to stop, but chickens are out dodging a tooth paste blast. Soon, Numbuhs 4 and 5 are taken over and than 2 and 3. Mr. Jelly is about to finish off Numbuh 1 and succeeds doing so. Mr. Teeth come in and throws a whip of taffy at Knightbrace. Mr. Jelly eats it and it is discovered that it's his only weakness. But the taffy gets stuck in the machine and Numbuh 1 is freed. In the end, Mr. Jelly is tired of eating taffy and his machine is stuck to taffy meaning it can't move. Mr. Teeth claims that his brother in law will take the candy store and offers the kids, a free check-up again. The team laughs and Numbuh 4 calls Mr.Teeth a freak once again. 
04a "Operation: P.I.R.A.T.E." 1, 2, 3, 4, 5 Stickybeard December 13, 2002 (2002-12-13) 104a

Expanded Acronym: Pirates Invade Repository And Treats Extracted
Candy pirates steal Sector V's candy, including Numbuh 5's secret stash.A pirate ship is moving through the neighborhood and leveling everything in its path. Meanwhile, in the Sector V Treehouse, Numbuh 5 opens a treasure chest full of candy and gives it all to the rest of Sector V. Suddenly, gum wads start coming through the wall and hitting them. It's the "Sweet Revenge" pirate ship. The pirates on the ship all board the treehouse. Numbuh 5 quickly hides the treasure chest full of candy. The pirates and the kids fight. Sector V manages to defeat some of the pirates with their SLUGGUHs, but the pirates soon overwhelm them. Having secured the treehouse, two of the pirates, Chewy and Gooey, signal this to the chief pirate, Stickybeard, who promptly comes in. Stickybeard is a candy-obsessed pirate, given the lollipop stick he has with him (that is, it's just the straight part of the lollipop) with gum on the end of his peg leg, some candy is stuck in his beard, a candy cane for a hook hand, and his teeth are in really bad shape. He demands all the candy, and Numbuh 5 refuses, saying he can have anything except the candy. But the pirates still take all the candy and take it to their ship. The pirates are about to leave, when Stickybeard notices the hidden treasure chest of candy. He takes it, too, and Numbuh 5 manages to burst out from beneath the pirates that were holding her and the other Sector V members dog pile and grab the treasure chest.

She says there's no way she's letting go of the candy, so he just takes her and the chest and warns the rest of the Sector V members not to follow them. The ship "sails off" and Chewy and Gooey bind Numbuh 5 to the mast with licorice, but she just eats it and gets free. She sneaks around and tries to take the treasure chest with her. The pirates notice her and try to attack her, and she's about to get away, but the weight of the chest pulls her down. Stickybeard takes the chest and throws it into the hold of the vessel with the rest of the candy.

Seeing how much Numbuh 5 likes candy, he offers to make Numbuh 5 his first mate, and that they'll rob kids of their candy, and that she'll get all of his candy when his teeth are completely rotted. He tells her that she'll have all the candy for 200 miles. He adds that the 200 miles is in nautical miles, which he believes is more than normal miles. Numbuh 5 thinks about it, but then rejects Stickybeard because she doesn't want to leave the KND.

Stickybeard makes Numbuh 5 walk the plank, but Sector V arrives and saves her in the nick of time. The kids had reconfigured their treehouse into a flying ship and they proceed to attack the pirates. This time the KND manage to take out the pirates. During the course of the fighting, Numbuh 5 tries to find her candy and finds it deep down inside the ship's hold. She's about to leave with it, but Stickybeard interferes once again. Numbuh 5 says she will see Stickybeard at the dentist. Then the two engage in a classic sword fight using candy cane swords, but Stickybeard manages to destroy Numbuh 5's sword, much to both of their displeasure, and he pins her against the wall.

Meanwhile, Numbuh 2 and Chewy and Gooey are fighting over the steering wheel, causing the ship to move about in different directions. The steeple of a building smashes open the hull of the vessel, releasing all of the candy and stopping Stickybeard from finishing off Numbuh 5. A bunch of kids all see it and start eating the candy. Numbuh 2 asks Numbuh 5 if she's okay, and she says she's feeling sweet. The episode ends with Stickybeard, Chewy and Gooey sadly rowing off into the sunset in a really small rowboat named the "Bittersweet".

Expanded Acronym: Crazy Old Woman Goes Increasingly Really Loco
An adult, Lasso Lass, that acts like a kid, wants to help Sector V defeat Mr. Wink and Mr. Fibb.Sector V is retreating from Mr. Wink and Mr. Fibb's Superchair robot, and Numbuh 2 holding some kind of glowing rock in his hand. Suddenly, a rope appears and grabs Sector V, saving their lives. The robot stops and Mr. Fibb and Mr. Wink don't understand what happened. The person who saved them resembles a cowgirl. The mystery person tells Mr. Wink and Mr. Fibb that they can have the KND and the glowing rock over her dead body. Mr. Fibb and Mr. Wink fire missiles at her, but she jumps away. However, Sector V loses the glowing rock they had from before. Sector V all wake up in a treehouse... but it isn't theirs. This one is a fairly broken-down in a strip mall. The cowgirl from before appears, and she introduces herself as Lasso Lass. She claims to fight adults, despite the fact she appears to be at retiring age. She's also the last member of the Cowboy Kids Club, which seems to be some KND-style organization. Lasso Lass shows Sector V around, except all of her "technology" she has is really outdated.

But everyone except Numbuh 1 is absolutely amazed at it for some reason. (When Lasso Lass shows her tin can phones, she says, "Hello, can you read me?" and Numbuh 1 replies: "Hello, would you like to accept a collect call FROM THE TWENTY-FIRST CENTURY!?")

Meanwhile, Mr. Wink and Mr. Fibb are arguing about whether or not they should open the dome (they're referring to the thing that the KND were running with earlier). Back at Lasso Lass' treehouse, while the rest of the KND are continually impressed by everything, Numbuh 1 gets impatient. Numbuh 1 notices a picture of what were some ex-members of the Cowboy Kids Club, and Lasso Lass says they were really good adult-fighters until they grew up. Then she says that with Sector V they can reform the Cowboy Kids Club. But Numbuh 1 points out they're not cowboys and that you can't really fight adults if you're an adult. Lasso Lass gets mad and says she's not an adult. The two argue about whether she's an adult or not and Lasso Lass claims she can do anything the KND can, so Numbuh 1 challenges her to go get the dome. Lasso Lass leaves on her horse Clip-Clop to retrieve the rock in the dome. Numbuh 1 wants to leave, but the rest of the KND insist on staying and waiting for Lasso Lass.

A whole day passes, and Numbuh 1 says they should leave. They're about to leave when Lasso Lass calls them on her old radio. She starts saying that they're having a pizza party at Mr. Fibb and Mr. Wink's house, but then says that they shouldn't come and it's a trap. Meanwhile, Mr. Fibb and Mr. Wink have Lasso Lass and Clip-Clop tied up suspended over what seems to be a pool of acid. Numbuh 1 shows up with a pizza box, and says he has to check to see if there's onions on it, and then he has to "call this one in". Using one of those outdated telephones, he calls "Kids Next Door, BATTLE STATIONS!" Sector V appears in Lasso Lass's Cowboy Treehouse, transformed into a giant horse robot. Mr. Wink and Mr. Fibb pull out their Superchair robot and they fight with them. Finally, the two robots collide and explode.

Next thing we see, the Sector V are also tied up and suspended over another pool of acid. Mr. Fibb accuses Lasso Lass for never growing up, and Mr. Wink and Mr. Fibb finally open the dome -- it turns out it was just a wig, which Mr. Fibb puts on. It turns out that both Mr. Wink and Mr. Fibb were once members of the Cowboy Kids Club. Mr. Fibb is mad at Lasso Lass because she only liked people with a full head of hair, and he was bald ever since the age of 14, so she didn't go to the prom with him. The branch that was holding up the rope Lasso Lass and Clip-Clop was tied up in snaps and she is free. She says she thinks Mr. Fibb looks really cute with the hair (though she calls him "Timmy"), and says he's so cute she could kiss him. She's just about to, and he gets really scared and runs away. Mr. Wink also starts running from Clip-Clop, who seems to be in love with him. Lasso Lass and Clip-Clop gallop after them into the sunset, leaving the kids still suspended over the acid pool. The KND (except for Numbuh 1, of course) are all bidding them farewell using "wild west" terms (i.e., "May our trails cross again!"). Numbuh 1 frustratingly demands that they cut it out, but they don't listen.

Expanded Acronym: Turnips Unfortunately Reaching Near Infestation Point
When turnips are found everywhere in Sector V's treehouse, they go to the source: a giant turnip.Numbuhs 1, 2, 4, and 5 are fighting a huge rabbit robot named H.I.P.P.I.E.-H.O.P. Soon it's lunch break and Numbuh 3 jumps out of H.I.P.P.I.E.-H.O.P., which she was controlling. They all split up and tried to get food, but turnips replaced the water and everything else. Numbuh 1 suspects someone wants them to eat the turnips. Since the turnips wore down the scanners, Sector V takes the P.I.P.E.P.O.D., with Numbuh 2 driving, and fly down into the huge turnip roots to find the source and stop it. They are traveling through the roots of the turnip, while the mini-turnips eat through the hull of the P.I.P.E.P.O.D. Sector V reaches the target and quickly escape when the turnips completely destroy the P.I.P.E.P.O.D. After escaping, they see the giant turnip that's causing all the problems. The turnip farmer tells Sector V that with the turnip, he'll be sure to get first prize at the county fair. Suddenly, a rumbling sound occurs.

Sector V discovers that they're up against a giant turnip monster. While Numbuhs 1, 2, 4 and 5 are being tortured by the turnip, Numbuh 3 invites H.I.P.P.I.E.-H.O.P. to come over. Numbuh 4 thinks it's a stupid idea, but Numbuh 1 considers it to be a good idea and tells Numbuh 3 to tell H.I.P.P.I.E.-H.O.P. it's a Code X79. H.I.P.P.I.E.-H.O.P. arrives and frees Numbuhs 3 and 1, but is then destroyed. Numbuh 1 said he thought for sure H.I.P.P.I.E.-H.O.P. would work, but it didn't. He angrily kicks the turnip, which to his and the others' surprise, falls over and rolls off a cliff into the ocean. The turnip farmer chases after it, calling that he needs it to win the fair. After the "End Transmission", some men on a ship see "a giant turnip" and wonder what it's doing there, before it attacks them!

Expanded Acronym: Miniaturization Is Now Issue - Golfing Opposite Looney Fanatic
After Numbuh 2 beats a mini-golf champion at mini-golf, the golfer shrinks Numbuh 2, and a whole lot of sights from around the world.The episode starts with Sector V (minus Numbuh 2) running for their dear lives as they are chased by a giant kid named Big Brother (no relation whatsoever to the Big Brother of politics). Numbuh 2 then shows up in a D.A.R.T. and tries to hit Big Brother with it but misses. However, he ricochets about the neighborhood, ultimately hitting Big Brother in the head, and knocking him out. Sector V are walking home, but they don't get far when a golf ball hits Numbuh 2 on the head, knocking him out. When Numbuh 2 comes to, he examines the ball and it belongs to a fellow named Rupert Putkin. He feels weird about Sector V holding his ball and gets it back. Numbuh 5 is surprised that they have champions in mini-golf. Rupert tells everyone sharply that the game is called miniature golf. He then speaks arrogantly about how if he were to play Numbuh 2 "one zillion, billion times", he'd beat him each time. Numbuh 2 promptly accepts the challenge despite the fact that he had never actually played it before. The two are now engaged in the game, which Rupert is very good at, while Numbuh 2 isn't, even though he managed to get a hole-in-one with a crashed plane. Pretty soon, they reach the 18th hole, everything depending on whether or not Rupert can get a hole-in-one here or face living the rest of his life in disgrace. Obviously, Rupert is tense and Numbuh 2 tries to relax him by saying it's only a game. This arouses Rupert's agitation and he frustratingly swings his club about wildly. In the process, he accidentally hits the ball straight up and it lands on the tee. Thus, he loses the game and Numbuh 2 wins. A reporter asks if he will go pro, but Numbuh 2 declines, claiming that mini-golf is dumb. Rupert hears his words. By nightfall, Rupert is still at the course and he finally snaps (as does his club). Back at the treehouse, Numbuh 2 hears the door knocking. He answers and is blinded by a bright light. When he comes to, he is surrounded by the world's historical monuments. He is pleased with where he is until a golf ball hits him on the head. Rupert (now calling himself the Great Puttinski) had shrunken the world's monuments (The Golden Gate Bridge, the Sphinx, the Eiffel Tower, etc.) with the Smallifying/Bigifying Ray and used the monuments as the courses in the Ultimate Miniature Golf Course, which is merely in someone's basement. Rupert had used the ray to shrink both the monuments and Numbuh 2, so they could have a rematch, only this time, Numbuh 2 would be at a "small disadvantage". Suddenly, Rupert's mother calls him for dinner, but he says he's busy destroying his nemesis right now. His mom says he can destroy his nemesis later, but he ignores her, and the game begins. Numbuh 2 is constantly lucky with his swings and makes one hole-in-one after another. When Rupert and Numbuh 2 reach the final hole, Rupert is disgusted to learn they're both tied. But it doesn't matter to Rupert because if he can get a hole-in-one through this hole, the Smallifying/Gratifying Ray will be activated and it will shrink the entire Earth to the size of a golf ball so Rupert can play golf with the entire universe. Numbuh 2 will have nothing to do with taking a shot that can shrink the world, but Rupert says that the miniature Numbuh 2 will be the ball! Numbuh 2 is now tied up and placed on the tee. He tells Rupert that he should not get worked up over a stupid game and Rupert yells, "IT'S NOT A STUPID GAME!" In frustration, he again flails his club around, but he accidentally hits Numbuh 2 with it. Numbuh 2 starts rolling toward the hole that will activate the ray. He reaches the hole and the ray is activated, to Rupert's delight. But Numbuh 2 then goes bouncing about after he gets flung from the hole, finally hitting the ray machine's switch so that it now is switched from "smallify" to "bigify", increasing the size of the monuments and Rupert, too. He starts to get really upset because, with each step, he is destroying his golf course. Meanwhile, Numbuh 2 is still bouncing around the room. He finally hits Rupert in the head, knocking him out, while the shrink-ray machine destroys itself on one of the monuments. Back at the Sector V Treehouse, Sector V congratulates Numbuh 2 on saving the world twice in one day. To celebrate, they decide to play ping-pong... with the still-shrunken Numbuh 2 as the ball!

Expanded Acronym: On Fourteenth Floor Is Corporate Evil
When his father brings Numbuh 4 to work for "Bring Your Daughter To Work Day", Numbuh 4 discovers his father's boss plans to send him and all the girls to Pluto.It's "Take Your Daughter to Work Day", and yet Numbuh 4's dad is taking him to work because he doesn't have a daughter. Numbuh 4 isn't thrilled about this at all, especially because he'd rather not be around girls. They arrive at the elder Beatles' job. They pass by a black limo, which Numbuh 4's father's boss, Mr. Boss, climbs out of . The Beatles go into the elevator, which has a bunch of girls in it. Numbuh 4 gets really annoyed by them, and is about to befall harm on one when they leave the elevator. It turns out that Numbuh 4's father works in a cubicle. Numbuh 4 gets bored and leaves. When he's in the hallway, a stampede of girls runs though. He ducks into a door to avoid them and discovers that Mr. Boss is planning on sending all the girls to Pluto, promising to take care of the boys next week, the idea being their parents will have more time to work for him if they don't have kids to go home to. Basically, the plan is to lure them into a party room, which is really a rocket in disguise. Numbuh 4 is planning to get out of the building now that he knows the plan, but the stampede of girls comes back and he's forced into the elevator. The elevator goes up to the highest floor, and they enter a party room, filled with Rainbow Monkeys (and various Rainbow Monkey accessories). The girls start playing and singing the "Rainbow Monkey" song. Numbuh 4 gets really panicky and tries to find some way to escape, but keeps getting interrupted by the girls. He finally finds an air shaft and is about to jump down into it when he finds... Numbuh 3? (Her mother apparently works in Accounting.) She, of course, wants to save the others. Numbuh 4 reluctantly agrees to do so, but they don't pay any attention to him trying to tell them they're on their way to Pluto -- until Numbuh 4 tells them that if they go down the shaft, they'll find Rainbow Monkey video games. The girls jump down it one by one, but it takes off before Numbuh 3 and Numbuh 4 can jump down the chute. Numbuh 4 tells Numbuh 3 that she can still make it and pushes her out of the rocket to save her and leaving him to go to Pluto. Of course, the air shaft leads to the office where Mr. Boss and his technicians are, and the girls all start messing with the computers monitoring the rocket because they think they're the video games. This has the result of making the rocket (with Numbuh 4 in it) malfunction and move in a bunch of random directions. Mr. Boss, naturally, is really, REALLY furious. Numbuh 3 lands in the control room just as Mr. Boss is leaving in a huff. She starts chasing after him and he gets into the elevator, tauntingly saying "I hope your friend likes Pluto!" She pursues him using a second elevator, but when she finally gets out, he's already about to leave in his car. But then, just when the car's driving out, the rocket crashes right onto it. Numbuh 4 manages to get out. Both he and Mr. Boss are dazed. Mr. Boss screams at Numbuhs 3 & 4 for ruining him and inches forward to really hurt them. But before he can, all the other girls start hugging him, and thanking him for the party. Numbuh 4 returns to his dad's office, and he says that it turns out they're having a "Bring your son to work day" next week, too. Numbuh 4 groans

Expanded Acronym: Am Really Cold That Is Certain
A fellow operative, Numbuh 30c, is sent to help Sector V stop a villain from using a weather machine to make no more snow days for school.The episode begins with narration by Numbuh One. Apparently the KND caught word that a mad scientist was building a machine to stop kids from ever having snow days. They decide to destroy the machine, and to help them on the mission, Moonbase sent an elite operative Numbuh 30c to join them. Numbuh 30c is dressed in a brown parka with goggles and a scarf, essentially preventing anyone from seeing his face; the scarf moves every time he talks. Numbuh 30c leads them to a lab in the middle of the tundra, where Professor XXXL (Triple-Extra Large) is conducting research. The KND (minus Numbuh 4, who stayed back with Numbuh 30c) leave their transport, the S.N.O.W.S.U.B., to attack the lab on their S.K.E.E.B.I.K.E.'s (Super Kool Environmental Engine Bike Is Kinda Enormous). Professor XXXL, who has gone to get a bowl of soup, notices them and sends his "Minestrone Missiles", missiles full of minestrone soup, at the KND. When they destroy the S.K.E.E.B.I.K.E.S., Professor XXXL gloats over Numbuhs 1, 2, 3 and 5, who are lying in the snow. They return to their feet and attempt to chase the Professor, but the snow is too deep to run in. Back at the S.N.O.W.S.U.B., Numbuhs 4 and 30c receive a message by Numbuh 1 to launch the S.N.O.W.S.U.B.'s missile. Numbuh 30c fires it, but seemingly aims it wrong and hits the KND. Numbuhs 1, 2, 3 and 5 are left naked and shivering cold in the snow, and a couple cutscenes later, when they are getting their clothes back on, Professor XXXL transforms his lab into a giant mechanical tortoise. After it briefly chases the KND, Numbuh 1 calls for a "Code Whale" which reveals that the S.N.O.W.S.U.B. is in fact a massive vessel. The vessel swallows the Professor's lab and deposits it into a huge indoor stadium, where Numbuhs 1, 2, 3 and 5 are demanding his surrender. Suddenly, Numbuh 30c appears on a nearby screen, with Numbuh 4 tied and gagged in the distance. It turns out that Numbuh 30c was working for Professor XXXL. He then throws off every last bit of snowgear to reveal himself wearing Hawaiian clothes (though his goggles and hat still hide his face.) He says his name, "Numbuh 30C" (30° Celsius), should have given him away. He explains that 30° Celsius is equivalent to 80° Fahrenheit. Numbuh 30c attempts to free Professor XXXL, but Numbuh 4 manages to free himself and attack Numbuh 30c. Numbuh 4 and 30c's fight causes the S.N.O.W.S.U.B. to self-destruct, sending everyone falling into the snow. Numbuh 4 furiously demands why Numbuh 30c would betray them. Numbuh 30c, crying, says it was only for a snowcone, only then is it revealed that Professor XXXL was merely trying to create "the perfect snowcone". The Weather Control Device was being created by another scientist, Professor Bob, who has his own lab. The episode ends with Bob saying that his machine is nearly complete and that kids will never have another snow day again!

Expanded Acronym: Lice Interrupt Cheese Eating
The DCFDTL attack Sector V's headquarters with an infestation of hair-eating lice. A parody of Aliens. The story begins when Numbuh Five is searching for a way out in the Delightful Mansion after stealing something from the Delightfuls, until she runs into the Delightful Children from Down the Lane, who are about to sic their Knightamaton, Sir Toasty on her. She quickly grabs a fire extinguisher and uses it to fly over the Delightfuls and Sir Toasty. The Delightfuls sic Sir Toasty on her, and just before the door closes, Numbuh 5 makes it out, but dropped her hat. She quickly grabs it and heads home. As she gets back to the Treehouse, she takes out what she stole from the Delightfuls: Tortilla Chips, compliments of the Delightful Children. The KND start to eat their Nachos and Numbuh Four tells Numbuh 5 that she could've visited the Deli for the Tortilla Chips, but Numbuh 5 tells him the Chips taste much better when you steal them from the Delightfuls. As she's about to eat her Nachos, her head gets itchy and keeps itching it until a giant lice bursts out of her cap, and this was no ordinary lice: this species of lice were hungry for hair. Numbuh One tells her that the Delightful Children gave her a lice-infested hat. They hear a scream coming from Numbuh Three's room and as they get there, they see that Numbuh 3's dolls and stuffed toys have been eaten! Numbuh 1 tells Numbuh 3 they'll get her new toys, but she doesn't want new toys, SHE WANTS REVENGE!!! As Numbuh 5 returns to the Treehouse with a new hat, they decide to squish the lice and when they see the lice eating Numbuh 3's bed, they run back to the kitchen. After they lose the lice, Numbuh Two bumps into a huge monster lice and tosses the bowl of Nacho Cheese at it, causing it to melt. They realize their weakness is Nacho Cheese and gear up for the fight, but right when they are about to get more cheese the rope for the cheese pourer falls off. They look up and see that a louse had eaten some of the rope. When it sees that it has been caught in the act, it screeches and runs away. When they notice their cheese supply is running low, they'll have to get more at the Cheese Repository on the 67th floor. While combing the Treehouse for lice to exterminate, Numbuh 4 becomes a bit scared, and walks in the wrong hallway. He runs into the lice and gets his hair eaten. They make a run for it until they reach a path that may lead to... a long way down in the treehouse. Numbuh 3 tells them to go on, because she vows revenge on the lice for what they did to her dolls. As the lice approach her, she blows up the room with a cheese detonator. As they continue their way up to the cheese room, the lice capture Numbuh 2, but Numbuh 2 tells them he'll hold them off. Numbuh 1 and 5 reach the cheese room. Numbuh 1 learns that the lice are starting to take over, so he raises the pressure in the main tank to fill every nook and cranny in the Treehouse, and then, the next thing they should do is hit the purge button, which will cause cheese to flood the Treehouse. Before Numbuh 1 could reach the purge button, the Queen lice emerges from the ground and attempts to snack on Numbuh 1's scalp, but she couldn't: he was already bald! The Queen is grossed out by this and throws Numbuh 1 into some boxes. She decides to snack on Numbuh 5's scalp, but Numbuh 5 uses her NACHOWITZER to do what she did to escape the Delightful Manor so she can reach the purge button. Unfortunately, Queen lice begins snacking on what's left of her ponytail braid. Numbuh 5 finally reaches the button, but Numbuh 2 enters suggesting one of his cheesy puns. Numbuh 5 hits the button and the cheese floods the house, with the exception of the Uno Household, of course. While the Delightful Children Down the Lane take a stroll around in the park, they are tripped and Lenny drops his headgear. The "adult" behind the newspaper gives it back to them and as they walk away, Lenny starts scratching his head. The "adult" was really the KND in disguise and replaced the real helmet with a helmet infested with lice.

That lead to Numbuh 1 saying that he and Lizzie weren't going 'out' out which makes her angry and leaves him on the ground. After she leaves, Numbuh 4 makes a comment on women and gets punched by Numbuh 3 and Numbuh 5 all into the night. The next day, Numbuhs 1, 2, and 4 are going to get new comics and Numbuh 3 and 5's girl magazines. On the way there, they see Lizzie and she gives Numbuh 1 a gift, apologizing about the bad date last night. It turns out that the gift was a boyfriend helmet. Nigel puts it on and Lizzie controls his romance feelings using a remote. Lizzie grabs Nigel and tells him he's taking her on the most romantic date ever. Numbuh 2 and 4 buy the comics and magazines and return to the treehouse. While Numbuh 4 is complaining about buying the cruddy girl magazines, Numbuh 2 tells Numbuh 5 about the helmet. After realizing it was a boyfriend helmet and if they don't stop it, Nigel will be forced to love Lizzie forever, the team goes to the restaurant to help Numbuh 1. At the restaurant, Numbuh 1 and Lizzie were eating some food. Lizzie was telling Numbuh 1 about being engaged, getting married, and not seeing his stupid friends anymore. Suddenly, Numbuhs 2, 3, 4, and 5 appear, punch the waiter, and prepare to take Nigel home. Lizzie uses the remote and commands Nigel to destroy his friends. Numbuh 1, controlled by the helmet, agrees to do it. Numbuh 1 battles Numbuhs 2, 3, 4, and 5 and he lands on the table. The team shoot a bunch of things at him until he's covered by lots of goop and nets. Lizzie grabs the remote and turns the knob to maximum power. Nigel escapes and pins everyone to the wall using forks. When Nigel returns to talk to Lizzie, the check comes. Nigel is furious about the price of the meal that his helmet fuses and it breaks. When Numbuh 1 tells Lizzie not to do that again, he looks around and sees his friends on the wall. Nigel asks Lizzie if she wants some ice cream. She says yes and they leave the restaurant, leaving Numbuhs 2, 3, 4, and 5 there. It turns out Nigel and Lizzie both like pistachio ice cream

The KND are all watching. Numbuh 1 thinks that the teenagers are all going to the "Point" to turn into adults because they can't wait to grow up so they can boss kids around. Numbuh 1 says they have to find the coordinates of the teenager-to-adult factory so they can use their condiment kannon to shoot mustard there and stop the teenagers. The KND all crawl up the mountain and find the parking lot. They force open the door to try to find some teenagers, and then get really grossed out and retreat (all except Numbuh 2). The impression may be that they found teenagers having "coffee". But it turns out the car was empty and it was just a bunch of really old food in there, Numbuhs 2 and 4 eagerly dig in. Numbuh 1 tells the KND to spread out and find the teenagers. They look in the cars to try to find teenagers, but completely miss teenagers moving around until Numbuh 5 notices them. They see some teenagers going to the "factory". Thinking they've found the coordinates, they send it to the condiment kannon, and it prepares to shoot mustard at the "factory". In two minutes it'll shoot the mustard. They're about to leave, but some adults find them. The adults grab the KND while the condiment kannon is preparing to fire. The adults throw the KND into the Point, but it turns out it's just a roller skating rink (not a factory!), and it's Kids' Nights, so kids can skate also. The cannon in outer space fires, flooding the whole mountain with mustard. The Point slips off the mountain because of the mustard.

Numbuh 4 is mistaken for a cat by an old lady after being stuffed in a kitty costume from his dispute with Numbuh 3.It's just a typical day at the Sector V Treehouse. While Numbuh 1 and Numbuh 2 are working on something, Numbuh 3 is playing with her cat doll, Mr. Huggikins, who is constantly saying, "I love you," and Numbuh 3 says she loves him back. Numbuh 4 grows tired of it and asks the rest of the team to get her to stop. Numbuh 2 asks Numbuh 3 to help him and Numbuh 1. Numbuh 4 goes up to the cat and says that "real dolls should be able to fight". He punches it a few times and it keeps saying, "I love you". He punches it again and breaks it. Numbuh 4 tries to put it back together without Numbuh 3 noticing, which she does. When she sees this, she naturally gets very distraught. Numbuh 4 tells her that he'll try and fix it up, but he accidentally places it on the C.A.T.U.H.P.L.U.N.K. (Chucks Alotta Things Up High Powered Largely Using Nebulized Ketchup). Mr. Huggikins is hurled into the air and is destroyed by a passing airplane. Numbuh 3 looks up sadly, then glares at Numbuh 4 with fiery eyes and a low growl, baring her fang-like teeth. Numbuh 3 forces Numbuh 4 to dress up as Mr. Huggikins to make up for causing the stuffed animal's destruction but as Numbuh 3 keeps hugging Numbuh 4, Numbuh 4 refuses to say, "I love you", which Mr. Huggikins always says after he is hugged. This makes Numbuh 3 angry and she keeps hugging him, hoping he'll say, "I love you", but he continues to refuse to say it. This makes Numbuh 3 sad and she runs off in tears. Numbuh 4 accidentally steps on the C.A.T.U.H.P.L.U.N.K. and is hurled into the air. Numbuh 1 notices he's heading for the Crazy Old Cat Lady's house.

While the Cat Lady is caring for her cats, she notices Numbuh 4 has landed in her house and wants to keep him as her pet. Numbuh 4 tries to tell her that he's a boy, but she doesn't listen. Back at the Treehouse, the team is getting ready to rescue Numbuh 4, but Numbuh 3 refuses to go with them because she's still mad at Numbuh 4 for destroying Mr. Huggikins and refusing to say, "I love you" when she hugged him. Back at the Cat Lady's house, Numbuh 4 tries to escape, but the cats won't let him. The team arrives to save Numbuh 4 and keep the cats distracted with a K.A.T.N.I.P.P.U.H. They grab Numbuh 4 and take off in the S.K.Y.C.L.A.W. The Cat Lady grows furious and the cats form into a massive Cat Monster, who chase after the S.K.Y.C.L.A.W. The Cat Lady manages to grab Numbuh 4 and is about to pull him into her grasp. As he's being pulled into the Cat Lady's grasp, Numbuh 4 tells the team to tell Numbuh 3 that he's sorry for what he did. Numbuh 3 arrives onto the scene and summons her toys with the T.O.A.S.T.I.E. The toys shoot the Cat Monster and Numbuh 4 is freed from her grasp. Numbuh 4 thanks Numbuh 3 for saving him and Numbuh 3 hugs him. When she does this, Numbuh 4 finally says "I love you," and Numbuh 3 wants him to say it again, but he just replies, "Don't press your luck."

The cats reform and resume chasing the S.K.Y.C.L.A.W. Numbuh 1 tells Numbuh 2 to take the S.K.Y.C.L.A.W. to Level 72 of the Treehouse. The S.K.Y.C.L.A.W. flies up to Level 72 and the Cat Monster follows. The Cat Monster lands on the C.A.T.U.H.P.L.U.N.K., hurling the Crazy Old Cat Lady and her cats into the sky. Eventually, the Cat Lady is forced to dress up as Mr. Huggikins rather than Numbuh 4.

Expanded Acronym: Find Another Stupid Task - For Our Oblivious Dodo
Numbuh 3 is sent on a mission for her birthday: to get a fast food meal. But the restaurant is actually for sharks, with kids on the menu, thanks to a new money-making scheme by Chester. It is Kuki's (Numbuh 3's) 10th birthday, and as Kids Next Door tradition, whatever her birthday wish is when she blows out her candles is granted. Her wish this year was to direct a mission. Numbuhs 2 and 4 are shocked at this, thinking she'd want a new Rainbow Monkey or a unicorn or something similar to her tastes. They also doubt that she can actually lead a mission on her own, and tell this to Numbuh 1. He understands their concern, and gives her a simple 'mission': to order a kids meal from the newest fast food restaurant, Burger Frenzy. When she enters and orders the meal, she discovers Chester is running the business. He then proceeds to turn her into a burger by topping her with ketchup, mustard, lettuce, and tomato, and stuffing her in an oversized fast food hamburger container.

At the drive through window, there is a family of sharks in a regular car (the car is full of water so they can breathe), who are ordering a kids meal for their son, who also happens to be celebrating his birthday - his wish was to get a kids meal from this exact restaurant (much to his father's anger of having to go up on land). Chester gives them the box and (the one he trapped Kuki in) the father sharks gives Chester some gold coins, and they drive off.

At this point, the rest of Sector V are getting restless, and can't believe that Kuki couldn't even get a simple burger (to which they speculate that there "must be a long line"). While sitting outside the restaurant, Numbuh 1 examines the sign in front, which reads: Try Our New Kids Meal! Kids Meal Contains 1 Drink, 1 Toy, and 1 Kid On A Bun. At this time, Numbuh 4 points out the car full of sharks, and the team realizes that 'kid on a bun' meant a literal kid, that kid being Numbuh 3. They race to stop the speeding car, which is heading back to the ocean, which shows a parody of the film Jaws.

Within the car, the kid shark is arguing with his father, saying he wants to eat his birthday meal right there in the car instead of waiting to get home; this angers the father shark, and he repeatedly yells at him, angering the mother shark, to which she says many times, "Don't you yell at my baby!". Right before turning to get onto the dock, the father finally gives in and tells the kid shark he can eat his meal if he stops whining, the kid shark much to his delight opens the burger box and licks his lips before he eats his special birthday burger.

Meanwhile, Sector V shoot a hook at the car, which eventually detaches, and costs them time in reloading it. They take aim and shoot one last time as the car heads up a dock, and miss by only a few inches. The car splashes into the water, and the burger box resurfaces and opens to reveal a huge bite mark and ketchup stains, but no Numbuh 3.

Back at the restaurant, Chester is planning to himself on how he'll round up all the kids in the neighborhood and feed them to hungry shark families, and make a fortune. In the background, we see Numbuh 3 covered in ketchup and mustard dangling from the piping in the ceiling. When he realizes she's still alive, he worries not that she'll be a threat, but that the shark family will want their money back. She attacks him and they have a battle, with him ending up on a bun as she did.

Numbuh 3 walks outside to find her teammates with a makeshift battering ram, attempting to break into the restaurant and an angry Numbah 4 holding a large axe, They realize she's alive and all crowd around her, to which she says that it was "the best birthday mission ever!", and they leave.

Back inside, Chester is still in the box when he hears car horns, and the next scene shows many cars full of sharks circling the restaurant probably wanting a burger.

Expanded Acronym: Ridiculous Exaggerations Possess Occasionally Real Truth
The KND each give an account of what happened to an ordinary package. It parodies The Matrix, old Superman comics, Dragon Ball Z, and Pink Panther cartoons The episode begins with a three-dimensional computer animated sequence featuring a CGI Numbuh 1 in a mostly featureless grid-based plane. In the opening narration, Numbuh 1 states that it is his task to retrieve "the goods", which appears as a floating white box. Placed throughout the space between Numbuh 1 and his objective are several obstacles and booby traps, which he quickly gets past. After he obtains the box, another trap is activated which in the process of escaping Nigel drops the box, which then floats away from him as he lies on the ground while the voice of the Delightful Children From Down The Lane "thanks" him for picking up the box for them. The next scene features "Numbuh 2 Guy" in a stereotypical lighthearted superhero comic setting. While mild-mannerly reading comics in the park, Numbuh 2 Guy hears a cry for help from Numbuh 1, who tells him that the "Devious Villains From The Consortium of Crime" have stolen the goods. He locates them using his "Penetra-vision" and confronts them, demanding that they hand over the box. When they open the box to him, it contains his one weakness, akin to Superman's Kryptonite. Before he passes out, Numbuh 2 Guy punches the box out of the villain's hands and sends it flying away.

This is followed by a very childish and crudely-drawn sequence in which Numbuh 3 meets "Boxy", here portrayed as a living creature, and declares him her best friend. After a brief montage of them playing, Numbuh 3 encounters a five-headed monster who demands she hand over the box. The blissfully oblivious Kuki willingly gives Boxy to the monster without any resistance and seemingly having no problems with abandoning her so-called "best friend".

The next sequence is a parody of Dragon Ball Z, with Numbuh 4 as Goku and the DCFDTL as Frieza fighting over the "Rectanguloid Power Charm". Numbuh 4 uses a Kame-hame-ha-like gumball attack, which seemingly defeats the villains. They then reappear and activate their "Full Power Evolution". In response, Numbuh 4 uses his own transformation, which unfortunately does nothing other than cause his hair to grow to a ridiculous size. He is defeated and loses the Rectanguloid Power Charm, vowing to not fail again as the scene ends.

Numbuh 5's story is a surreal cartoon in a style somewhat resembling Mo Willems' The Offbeats set to Jazz-style music. Carrying "the goods", Numbuh 5 is pursued by the Delightful Children, who in this scene share one body with five heads. They furiously yell "Give us that box! It's ours!", and when Numbuh 5 remarks that it isn't, they tell her to check it for herself. When she looks inside the box, loud, blaring trumpet music plays, causing all of them to jump and Numbuh 5 to drop the box. She picks it up and looks again, to the same effect. She makes a disgusted remark that it's anchovies, revealing that the box was nothing more than a pizza, and they had the Delightful Children's order the whole time. Numbuh 5 tosses the box at them, which they catch and say "Thank you" very sarcastically before taking their leave.

After all five segments, the episode finally cuts to reality, where Numbuh 86 is yelling at the members of Sector V for failing their mission: picking up a pizza. In the final shot, the employee at the pizza restaurant is seen calling for the Kids Next Door, who forgot to take their pizza after it was made.

A king forces Numbuh 3 to marry him, but she agrees because she thinks they're pretending. Meanwhile, Numbuh 4 will fight King Sandy for Numbuh 3.Sector V is spending the day at the beach, except for Numbuh 1 who hates the beach and thinks it's boring. He then leaves. Everyone else is having fun while Numbuh 2 and Numbuh 5 swim, Numbuh 4 is buried to his neck in sand, and Numbuh 3 builds a sandcastle, declaring herself princess of the beach. Then three bulky knights in sea shell armor who call themselves the Knights of the Round Towel destroy it and kidnap Numbuh 3. Numbuh 4 sees this and yells at them to let go of her, but he can't do anything to enforce it because he's stuck buried in the sand. Later he tells Numbuh 2 and 5 what happened and says that the knights made it personal by taking Numbuh 3. Numbuhs 2 and 5 tease him by singing "Wally and Kuki sitting in a tree K-I-S-S-I-N-G" which makes him blush and deny it pathetically claiming that she just owes him a quarter.

Meanwhile, the Knights of the Round Towel take Numbuh 3 to the giant Sandcastle of King Sandy. King Sandy thinks she's really pretty and tells the knights to let her go. Then he asks her if she wants to get married and she playfully agrees.

Outside on the beach, Numbuh 4 marches up to the Sandcastle with Numbuh 2 and 5 and orders the knights to give back Numbuh 3 or else. The knights also taunt him about liking her and again he fumbles and searches for an answer, finally insisting again that she just owes him a quarter. Then he launches himself from the catapult into the castle while Numbuh 2 and 5 simply take the front door.

Inside the castle Numbuh 3 is dressed in a pretty wedding dress. King Sandy looks out the window and spots Numbuh 2, 4 and 5 battling the knights with sand shovels. He grabs Numbuh 3 and runs up an outdoor set of spiral stairs to the wedding room. Numbuh 3 spots Wally on the balcony below her and exclaims to him happily that she's getting married. Numbuh 4 is horrified and slowly backs away, and ends up falling off the edge of the castle and is knocked unconscious.

He later wakes up to find himself tied to a pillar with Numbuh 2 and 5 just in time to watch the wedding. Numbuh 4 asks Numbuh 3 if she really plans on marrying King Sandy, or "that dork" but she tells him they're just pretending. King Sandy gets mad and tells her the king never pretends. Numbuh 3 decides he's crazy and tells him to forget it. He tells her that no one is getting in the way of his perfect wedding, including her, the bride. So he ties up Numbuh 3, dangling her from the ceiling and attempts to force her to marry him.

Numbuh 4 escapes from being tied up at the last minute and attacks King Sandy. They end up in an epic battle. King Sandy says that he must love Numbuh 3 very much but she's his. Numbuh 4 yells one last time "SHE. JUST. OWES. ME. A. QUARTER!"

Then high tide comes, destroying the castle. As the castle wall, made of sand, crumbles, King Sandy, who is standing on it, falls into the water. Numbuh 4 rushes inside in order to untie Numbuh 3 and escape the castle, accidentally forgetting about Numbuh 2 and 5. Numbuh 5, annoyed, yells at them and they go back to untie her and Numbuh 2. Once outside, they watch the giant Sandcastle collapse into the water.

King Sandy shouts that he will make a new castle and put them all in the dungeon but then his mother calls him and tells him to stop pretending (Sandy is outraged, saying that he doesn't pretend) and to bring his cousins, who are playing the Knights of the Round Towel.

Numbuh 3 then remarks that King Sandy is kinda cute. The others are annoyed and Numbuh 4 tells her to "Just shut up and give me that quarter you owe me." Numbuh 3 is confused, and says "What quarter?"

Expanded Acronym: Twins Reconnaissance Increases Peril
Numbuh 3 is followed by the ITFBTM (Interesting Twins From Beneath The Mountain), the cousins of the DCFDTL, when she goes to Japan, so they can infiltrate the Japanese KND headquarters.The episode starts with Father talking to "his children", supposedly the Delightful Children From Down The Lane. As the screen closes in on the back of his chair, we see he is not talking to the Delightful Children, but instead to someone else over the phone. He explains that one of the Kids Next Door is visiting her homeland in Japan (clips shown while he is talking reveal that the operative is none other than Numbuh 3 a.k.a. Kuki Sanban). He explains that once there, she plans to randevou with the elusive Japanese Kids Next Door. So, Father gives his agents the mission of following Numbuh 3 until she meets up with the Japanese KND at their HQ. Once Kuki has met up with the KND, Father's agents are instructed to contact his ninja army. He instructs them to call the ninja only if they are absolutely sure that they have discovered their HQ. From another clip we see Kuki on the plane, being handed a large pink lollipop by a stewardess. She happily accepts the sweet and the stewardess goes into a crew member's only cabin. Father tells his agents that he has chosen them because they are his most skilled agents, his most foolproof villains, his best trackers, and his most devious masters of disguise.

Then, the stewardess's head opens, revealing that she is actually a robot, and the heads of two children pop out of the opening. The Interesting Twins From Beneath The Mountain (twin brother and sister and world-class masters of disguise) assure Father that the mission will be easy for them. They state plainly that failure is an impossibility and laugh with Father. The scene changes to show Kuki walking out into the airport, still holding the lollipop, with a large woman who has a dog behind her.

The woman is revealed to be the Interesting Twins in disguise again (the sister is at the head and her brother is the dog) and they believe that since Kuki is alone, the assignment will be twice as easy. They begin laughing, but stop short when they see that the airport is having a free sombrero day, meaning that almost everyone there is wearing a large green or red sombrero. They label this as only a minor setback and simply resolve to double their efforts.

Kuki, who is wearing a sombrero herself, walks through the airport, stopping briefly to pet a barking dog, which stops barking and licks her when she pets it. She walks on and the Interesting Twins walk by the dog as well. The boy shoots it in the face with a small water pistol and the girl kicks it in the face. Because of the dog's struggling, the cage opens and the dog proceeds to go after the twins and attack them, stopping only when their robotic disguise suit is destroyed. The sister is the first to recover from the attack and labels it another minor setback.

Kuki, still completely oblivious, is followed by the twins as she boards a transit. The twins follow, disguised in an overcoat and hat, and sneak past the conductor and onto the transit. Only, they realize too late that they had boarded the wrong transit, which was back to back with the one Kuki was on, and are now headed in the opposite direction. They run out onto the back of the transit and jump onto a train that is passing by, in the right direction. From there, they jump onto the right transit this time and go into the car they had landed on, which turned out to be the janitorial car. They give each other a look and smile as the scene changes.

When the scene changes, we see that the twins have disguised themselves yet again (this time as a woman and baby) with supplies from the janitorial car. They spot what they believe is Kuki's sombrero and jump up to catch her off-guard, only to find that it is not Kuki, but the same dog from the airport. They are frozen with fear and the dog attacks them again.

Meanwhile, the real Kuki has gone up to the front of the transit and is talking with the driver. She asks if she could drive the transit, to which he replies no. A quick sut-scene shows that the twins have managed to escape the dog by going into the next car and closing the door behind them. Another cut shows Kuki continually asking the driver if she can drive until she shouts out that she spots a panda on the tracks. The conductor abruptly pulls the stop lever, sending the Interesting Twins flying towards the front of the train, breaking through doors on the way until they go crashing out the front window. Kuki quickly says it was her mistake and that it was simply a shadow, not a panda. She asks again if she can drive, this time the driver responds with "okay".

The twins keep on going until their heads break through the wall of a building. They see Kuki go past, still oblivious of the two and the sister begins to say that she is losing her patience, but her brother responds that patience is a virtue. We then see Kuki dragging a large suitcase (which she didn't have before that point) to the curb and hailing for a taxi. The twins, this time hiding in a suitcase identical to the one Kuki has with her, get rid of her suitcase and wait for her to take them with her. A taxi pulls over and the driver puts the suitcase containing the hidden twins in the trunk.

Kuki opens the door of the taxi, revealing that she was only assisting an old woman in getting a taxi and carrying her bag. The woman thanks her and gets in. Kuki closes the door and wishes her to have a good time in France. The twins hear this and shout in surprise as the taxi starts, but a bump in the road sends them tumbling out of the trunk and falling to the freeway below them. They land on the back of another taxi, coincidentally, it is the one Kuki is riding in. The girl sees this and she begins yelling that she does not care about tracking Kuki to KND HQ anymore.

Her brother tries to interrupt, but she grabs him by the front of his shirt and yells at him. She says that Kuki has dishonored them both, but before she can finish her sentence, her brother interrupts by saying that it wasn't that. He is interrupted once again as the taxi inaverdently runs the twins into a tree branch and keeps going. The sister, still incredibly angry, orders her brother to summon their biggest, most destructive ship. He complies and summons their Deadly Super Ship via his yin-yang watch. Before they can use it to do anything however, it is destroyed when it is hit by a large truck. The brother suggests that they summon their second most destructive ship and his sister hangs her head.

The scene changes and shows them riding a two person bicycle with the brother at the front, tracking Kuki's movements via the lillipop tracking device they had given her at the beginning of the episode. His siter orders him to engage full assult mode and they pedal ahead. Meanwhile, Kuki has gotten out of the taxi and throws the lillipop away. The twins stop at the trash can, believing her to be somewhere close by. The sister, still enraged, jumps into the garbage can in search of Kuki. Her brother timidly asks her to calm down, but she grabs him by the front of the shirt and begins yelling again, but before she can finish, a garbage truck picks up the can and both of them are thrown into the truck.

Sometime later, the twins are dumped out again at a garbage dump, compacted into a cube of garbage. They see Kuki skipping past them and going up a hill, apparently still oblivious of the days events and the twins. The sister quickly takes up chase with her brother running after her. Kuki accidentally causes an avalanche higher up the mountain and both twins are caught in it off-screen. The scene changes and Kuki is looking into a traditional Japanese house as a tall figure comes into the room.

The twins finally catch up to her and the brother contacts the ninja army as his sister rants about their victory. Unfortunately, her triumph is cut short when they see not the Kids Next Door, but an old woman, supposedly Kuki's grandmother. The sister calls off the attack and crushes the communicator. She then begins yelling at Kuki because she was supposed to be meeting the Japanese Kids Next Door, not her grandmother. Kuki responds by saying that the woman is not her grandmother, angering the sister even more. She says how she is a world-class master of disguise, but her rant is cut short when the old woman reveals herself to be not Kuki's grandmother, but the members of Sector V in disguise.

Having had all she could take, the sister sadly states how she is a failure and breaks down crying, the stress of the day having finally gotten to her. Her brother attempts to calm her down as he calls out the members of Sector V for doing this. He vows that they shall return, and leads his sister in jumping out the window. However, in his rage, he seems to have forgotten that they were on top of a mountain and the two fall a great height to the ground. The brother laments that at the very least the situation can't get any worse, but he is soon proved wrong. They are surrounded by numerous figures who have caused them trouble on their trip (the old woman, the transit driver, the taxi driver, and the dog), who reveal themselves to be members of the Japanese Kids Next Door. They proceed to close in on the twins as the transmission ends comes on-screen, supposedly to beat them up.

Which Numbuh 3, Numbuh 23, and Numbuh 12 went right in, but Numbuh 4 did not like the room, because it was filled with Rainbow Monkeys.

Expanded Acronym: Juvenile Escapes With Extremely Luscious Sweet
Numbuh 5 journeys to the exotic Al-Shugar Desert to recover her stolen candy, the Blurpleberry Supreme, and discovers she's not the only one searching for the powerful, mystical candy. In the desert, a mysterious young traveler girl in a blue robe is riding on a camel to a marketplace where all of the merchants are selling various forms of candy that look like jewels. The mystery person passes by various people selling "candy jewelry" until the person comes to a man named Al Sugarh, who seems to have been expecting her. She examines Al's wares of candy jewelry and soundly rejects them by knocking them on the ground, allowing some children to gobble it up. Instead of getting mad at this, Al says that this person is probably someone "whose discerning taste yearns for candies more succulent than such puny fare." He invites the mystery person into his tent. Inside the tent, Al Sugarh shows the mystery person a candy jewel called the Blurpleberry Supreme and asks the person if they know of its fabled qualities. The mystery person knows about it because Al stole it from her. At this point, it is revealed that the mystery person is Numbuh 5 . She warns Al that "a great candy taken in greed always turns sour," but Al dismisses this warning as an ancient superstition. Numbuh 5 is planning to save the candy for a special occasion. She then pulls her G.U.M.Z.O.O.K.A. on him. However, just as Numbuh 5 is full of surprises, so is Al, as he then has some henchmen wrap rope around her arms and tug her back, but Numbuh 5 defeats them by kicking a giant jawbreaker in their faces. She then unties herself. Meanwhile, Al grabs Numbuh 5's gun and repeatedly shoots her. She grabs up the jawbreaker and uses it as a shield to deflect the gumballs. One gets mysteriously stuck on Al's robe and he collapses. Numbuh 5 then grabs up the blurpleberry jewel and heads out.

Outside, Numbuh 5 trips on a rope held by some henchmen of an old rival of Numbuh 5's, Heinrich Von Marzipan, who takes the blurpleberry candy from her. It turns out she had left Heinrich in Guatemala because some "urgent business came up" and Heinrich was left holding a bag of sacred caramels when the authorities arrived and he ended up being grounded for a month. Numbuh 5 says that she would like to make it up to him and asks for the candy back. She approaches him, but is held back by Heinrich's henchmen leveling their swords at her and she steps back. Heinrich questions of the candy's importance to her and she repeats that she is saving the candy for a special occasion and Heinrich says that he is, too. He will use it to unlock the tomb of King Two-Tons-of-Candy.

Numbuh 5 warns him the tomb is cursed, but not only does he ignore the warning, he also gives her a "payment" for the jewel: a tiny bag of sugar-free candy. Numbuh 5 just tosses the bag in the air and all the candy within fall out. The kids that ate the candy from off of Al Sugarh's table come by again and eat all the candy in the bag, leaving Numbuh 5 to escape. Heinrich orders his men to find Numbuh 5 and bring her back in chains. He leaves the area in a candy tank. Numbuh 5, meanwhile, is riding on the back of the tank, so she is secretly riding with him.

Heinrich arrives at a pyramid, the entrance to the Eighth Sugary Wonder of the World. Heinrich gloats that now there are only seven as his tank smashes through the giant candy doors. He then climbs out of the tank and heads deeper into the pyramid, the blurpleberry jewel in his hands, while Numbuh 5 follows him from a safe distance. Heinrich reaches a door with an indentation on it. He places the jewel in the indentation and it opens, leading into the treasure room full of candy. Heinrich enters and discovers the sarcophagus of King Two-Tons-of-Candy. On the sarcophagus, the inscription reads: "From the forehead, ye shall control the sarcophagus. But share not and only taste asparagus." Heinrich begins to read the inscription, but doesn't finish because he doesn't care.

Heinrich opens up the sarcophagus, revealing a lot of candy and a pharaoh's headpiece, which has an indentation where the blurpleberry jewel fits. He puts on the headpiece, but before he can put the jewel into the indentation on the headpiece, Numbuh 5 shows up and warns him that he should have finished reading the inscription: "From the forehead, ye shall control the sarcophagus. But share not and only taste asparagus." Again, Heinrich dismisses her warnings and says that she just wants to take the candy just like what happened in Guatemala. Numbuh 5 protests that that wasn't what happened, but Heinrich just ignores her and puts the jewel into the headpiece. Then all of the candy in the sarcophagus comes out and engulfs Heinrich (he's controlling it), turning him into a giant candy-mummy. He cackles wickedly and taunts that he controls the candy and neither Numbuh 5 nor anyone else can have any. Heinrich then eats one of the candies, but spits it out, because it tastes like asparagus.

He then starts accusing Numbuh 5 of sabotaging the candy and proceeds to attack her. She retreats up the stairs, only to find the door locked, trapping her in with Heinrich, who is about to finish her off, but first asks if there's any last words. She says to give her back the candy. She then takes out a licorice rope and wraps it around one of the columns of the room and swings around on it, landing on Heinrich's head and removing the blurpleberry jewel from the headpiece's indentation, turning Heinrich back to normal. As she leaves the pyramid, Numbuh 5 repeats her adage that she says earlier in the episode: "A great candy taken in greed always turns sour."

Back at the Treehouse, the team is celebrating Numbuh 1's birthday. Numbuh 5 then shows up. She apologizes for being late because she had to pick up his gift from her. It's the Blurpleberry Supreme jewel. But Numbuh 1 hates blurpleberry; instead, he prefers cherry. Irritated, Numbuh 5 rolls up her sleeves and advances on Numbuh 1, saying she can't believe it. Numbuh 1 wonders what he said

Numbuh 3, still crying says that they never should've sent Bradley on such a dangerous mission. Which leads the rest of Sector V into talking about the situation. Then Numbuh 1 spits them into pears; having Numbuhs 2 and 5 going one way and Numbuhs 3 and 4 going the other, with Numbuh 1 going on his own. He tells his team if anyone spot anything suspicious to give the others a call on their communicators and they'll all come running.

She is almost out of the woods when the hound attacks her backpack and rips up her homework. Meanwhile, Valerie, a honor role student, finishes her report on why America is the greatest country.

Numbuhs 2 and 5 travel through the school jungle gym to help find the First Grade's missing pet bunny. A parody of Indiana Jones and the Temple of Doom.While Numbuhs 2 and 5 are heading off to lunch, they stop at the 1st grade hallway, which they find a barren wasteland. As they continue down it, they find that all of the students' clothes are tattered, and when they enter one of the classrooms it's destroyed. The 1st grade president says they have awaited the return of the Kids Next Door (as it was predicted in Art class). He says that their pet rabbit has gone missing and without it their crayons turned to dust, their milk soured, and everything had gone with it. This leads Numbuhs 5 and 2 to go after it (although Numbuh 2 is complaining about not getting lunch). A girl named Jessica runs up to Heinrich Von Marzipan and tells him that the chocolate volcano is nearby. Meanwhile, Numbuhs 2 and 5 come to the Jungle Gym. Numbuh 2 complains about missing lunch, but tells Numbuh 5 he's joking. He asks Numbuh 5 how far the Jungle Gym goes, and she replies that nobody knows, which echoes throughout the playground as the two operatives start to climb.

After a long trek, the two reach the chocolate volcano, where they witness Heinrich lowering Jessica's stuffed rabbit down into the choco-lava, Temple of Doom-style. Just as Heinie is about to lower the first-graders' pet rabbit, he notices Numbuh 2. Heinie orders his adult minions to fire on Numbuh 2, who swings out of the way and onto the cage, causing the cage to sway back and forth. Numbuh 5 leaps in to turn the crank so the cage doesn't fall in the choco-lava, but Heinrich steals his minion's lollipop gun ("Hey, that's mine!") and fires on his archenemy. Jessica offers her help, which Numbuh 5 accepts after she sees the crank (which had been stopped by a lollipop stuck in it) start to move again.

After a long fight, Numbuh 5 falls onto the cage with Numbuh 2 causing the cage to start falling at a tremendous rate, stopping just before the choco-lava, and Heinrich bids them goodbye in his native German. An angry Jessica pushes Heinie towards the edge, where he falls in. Just then, the volcano begins to collapse. Jessica jams the gears once more, and Numbuhs 2 and 5 climb back onto solid ground with both Jessica's stuffed bunny and the first-graders' real bunny. Back at the first grade classroom, the return of the bunny brings back everything the first-graders lost and they are thanked, but Numbuh 5 chases Numbuh 2 for one of his lame jokes.

After the end credits, we see a chocolate hand grab onto the edge of the chocolate volcano and we hear Heinrich's evil laughter, foreshadowing his next appearance in Operation: C.H.O.C.O.L.A.T.E

They then find Numbuh 5 is stuck to the roof, toothless; Baby Jackson then sits up and tells Sector V of the his plan for him and the other babies to steal teeth so they can talk and don't have to listen to baby talk, from adults like them.

Sector V begin fighting the Ankle-Biters. Numbuhs 1 and 5 end up cornered, and Numbuh 5 tells him to sing them to sleep. His singing is so bad it causes the Ankle-Biters to faint. They then take the babies back to the hospital, and Numbuh 1 asks Numbuh 5 where babies come from. She begins by saying "babies come from-", then the transmission ends.

End Credits: Numbuh 1 is frozen in shock. Numbuh 2 is disgusted and says "ugh". Numbuh 3 is running in circles, yelling "Ew, ew, ew, ew," Numbuh 4 is also frozen and freaked out with his hair standing up like he's been electrocuted. Numbuh 5 is nodding seriously to them. It cuts back to Numbuh 1, who, after a minute, says "Wait a second, babies don't come from New Jersey! .... They come from Philadelphia!"

Numbuhs 2 and 4 try to escape from an island inhabited by bully monsters. A bully-themed parody of Jurassic Park is shown here, after Numbuh 4 eats a burrito in the island's diner.Numbuh 2 and Numbuh 4 visit Bully Island, a bully habitat owned by Jerry Rassic (an obvious parody of Jurassic Park). Numbuh 2 is interested in the scientific aspect of it, while Numbuh 4 is only in it to see the different types of bullies on the island. After seeing a 'teasing time' (similar to feeding time, but instead kid crash dummies are set on swings and Spitballasaurises come and shot spitballs at them), Numbuh 2 asks Jerry anxioiusly if he's ever worried about his own safety, being surrounded by bullies all the time. Jerry replies that Bully Island is perfectly safe, and the bullies are in cages that keep them away from him and his sister Eliza, who also lives on the island. While showing Numbuhs 2 and 4 the main tower, an alarm goes off and Jerry informs them something is happening at another tower on the other side of the island, the same one Eliza is currently in. He hands them a gun that 'projects a holligram of the school principal' to ward off bullies, and Numbuhs 2 and 4 leave with his jeep to rescue his sister.

When they eventually get to the tower, they find Eliza hiding in the corner. Further inspection reveals it's not Eliza, but merely another crash dummy. On the digital map Jerry gave the two of them, he informs them that he had lured them into a trap in order to get revenge on Numbuh 4. Back in the first grade, Jerry had been sitting near one end of a teeter-totter, and Numbuh 4 jumped on the other end of it, causing Jerry's underwear to snag on the end nearist him and give him an ultra wedgie.

According to him, doctors had spent hours trying to remove the underwear from him, but couldn't, leaving Jerry with a permanent wedgie. He wants revenge on Numbuh 4, and his only regret was that Numbuh 2 had gotten involved, saying, "I'm so sorry Hoagie. We could have been friends. But you should know better than to hang out with a bully!"

As Numbuhs 2 and 4 try to escape, they are followed by numerous bullies shown earlier during their tour. Numbuh 4 tries to hold them off with the gun Jerry supplied them with, but it turns out to be a toy gun that pops out a piece of paper reading "KICK ME" (similar to many other cartoon fake guns) when he pulls the trigger. At one point, they come face-to-face with a Wedgiesaurus Rex (which all the others of the species have been sent to permanent detention).

Numbuh 4 tells Numbuh 2 not to move, because they respond to movement. After standing still for a moment, the bully believes they are no longer there and walks away; Numbuh 2 lets out a sigh of relief, to which the bully returns. Numbuh 2 makes a run for it, leaving Numbuh 4 at the mercy of the bully, who gives him multiple wedgies (all of which Numbuh 4 can name; the Around-The-World wedgie, the Texas wedgie, the yo-yo wedgie, etc.).

While running through the jungle on the island, Numbuh 2 finds a sheet of unfinished math homework on the ground. With it, he races back to Numbuh 4 and shows the paper to the bully, saying, "Hey, Wedgiesaurus Rex! I did your homework for you!" The bully drops Numbuh 4 and takes the homework from Numbuh 2. Just when it seems like they're off the hook, Jerry cuts in and yells at the bully to attack. All of the bullies on the island proceed to the clearing they are in, and close in on Numbuhs 2 and 4.

They eventually get back to their ship to find Jerry on board, attempting to leave the island. They push him off and he falls back to the clearing, where the bullies surround him. As the ship leaves Bully Island, the bullies (especially the Wedgiesaurus Rex) are really sad that their new friends are leaving. On the ship, Numbuh 4 asks Numbuh 2 if he could keep the wedgie incident just between the two of them (and the proceeds to show him his underwear, which is stretched to 4 times its normal size). Numbuh 2 takes the opprotunity to crack a joke, saying, "As far as I'm concerned, all of this is behind you.

A clown tries to get Numbuh 2, as he plays lots of jokes.: The episode starts with Numbuh 2 cracking bad puns during his report on King Arthur and knights. Later, Numbuh 5 punches Numbuh 2 and he asks what was that for. Numbuh 5 says it's for having her listen to those lame jokes. Numbuh 2 counters with a newspaper column saying he's the four star riot of fourth grade. Numbuh 5 than says the column was written by Numbuh 2. This doesn't effect Numbuh 2 and he asks if he should of given himself more stars. Outside of class, Numbuh 2 is confronted by a kid clown telling him to cut the funny business. Seconds later, Numbuh 2 tells a bad joke. The clown gets angry and has his two clown cronies to throw pie at him as a source of punishment. Numbuh 2 promises to never tell another joke again.

During the next few seconds, Numbuh 2 frequently tells jokes and gets hit by pie. Every time he gets hit by a pie, the students near him run away in terror. With each joke, he gets more nervous telling jokes. After those scenes, Numbuh 2 confronts Numbuh 5 who's eating lunch. Numbuh 5 tells Numbuh 2 that lunch is almost over and notices the pie and asks, "I thought you hated pie." Numbuh 2 says, "A couple of clowns offered me a pie I couldn't refuse." Numbuh 5 finds a fly in her soup and asks why would a fly be in her soup. Numbuh 2 attempts to answer this with a bad pun or joke but fails after glancing at the clowns, and breaks down crying wailing at not being able to take advantage of such a perfect setup.

Later, when school is over, Numbuh 5 notices a chicken trying to cross a road and Numbuh 5 asks why would a chicken try to cross a road. Numbuh 2 attempts to avoid saying the joke but is unable to resist the perfect setup to the oldest joke in the book.

The clowns, neverless take him away and throw him in a room with the clown father, Tony Clownarelli. Numbuh 2 asks why he's doing this and Tony begins a story. When he and his partner were at a kid's party, Tony tried to answer the most funniest joke of all. But he forgot the punchline. The kids at the party threw things at him which lead him to pass out. When he woke up, he found his partner gone. So now he's not letting anyone telling a joke so they wouldn't get hurt like he did. Numbuh 2 attempts to escape out of the room. Outside the room, is the inside of the circus where Numbuh 5 and her father are sitting watching. Numbuh 5 buys a excuse to send her father away.

Numbuh 5 than helps Numbuh 2 escape from the clowns. This ends badly as Tony and the clowns trap Numbuh 2 and 5 and are about to punish the two but Numbuh 5's father steps up. Tony recognizes Numbuh 5's father as his old partner and asks where he was all these years. Numbuh 5's father says that he discovered that his job was stupid. He makes more money as a doctor. The clowns agree and Numbuh 5's father says that he could get the clowns jobs cleaning doctors. The clowns get excited and Tony hands his nose to Numbuh 2 who wears it with pride. Tony and Mr. Lincoln do one act together but goes awry at the first joke.

Sticky accepts but loses to Abby. Stickybeard asks for 2 outta 3 but Numbuh 5 declines. So Stickybeard begins telling a tale in song, along with the rest of the candy pirates. The pirates tell the tale of Black John Licorice and his pirate crew who find a island near North Dakota filled with red licorice trees. Black John took all the trees but a terrible misfortune was exposed for him and the pirates. The fate was that the licorice turned black and every night, the pirates would turn into licorice and at dawn and day, they would become a pile of bones. The pirates soon discover from a gypsy fortune-teller that they must plant a licorice seed that she gives them on the island so the licorice would grow again, and the curse would be broken. The pirates do so but while on the island, the dawn rose and they became a pile of bones. Heinrich, Sticky's cabin boy at the time, and Stickybeard ventured on the island and found the bones of Black John. Heinrich spotted the seed and took it. Later, the pirates came to attack Heinrich but the two escape with the rest of Sticky's crew. But Black John was on their tail. This ends the song and Abby asks one question: What happened to the seed. Suddenly, we see Heinrich and he says he ate it! The pirates decide to plant Heinrich so the seed would grow inside him and the curse would still be lifted. But Stickybeard challenges Black John to a sugar chugging. Black John excepts and says that no man ever could out sugar him. Sticky then says, "Who said anything about a man?" and reveals Numbuh 5 behind him. The two duel and Black John loses. But Black John says this is a challenge to the death...of her blood sugar levels. So the two battle eating sacks of sugar and gulping down mugs of sugar. At last, Black John is winning as Numbuh 5's sugar level is going so high. Abigail loses but reveals this was all a distraction and Sticky's two pirate twins kick the seed out of Heinrich. The pirates come to punish Abby but the sun rises and the pirates become bones which is the reason why she distracted him for so long. Later, Heinrich thanks Abigail, though this still doesn't make up for what happened in Guatemala. Therefore, Abigail sends him back to the Arctic Base. Heinrich yells he will have revenge and while yelling, a humongous shadow of a ship is seen with the insane laughter of Black John which is exactly the same at the beginning.

Expanded Acronym: Senator Attacks Foes Endangering Today's Youth
When a kid-friendly minister receives a funding of approximately eleven-billion dollars, he uses it to build an army of Safety-bots, to make the world a safe place for children. But the robots grow more and more extreme in their actions, eventually planning to eliminate adults, and cover the Earth in bubble wrap.The episode starts out in the Capitol building in Washington D.C., where new laws are being reviewed (for example, the first law all the senators agreed on was making math class 70% more boring for kids). The Senate leader then calls up Senator Safely - he seems reluctant to do so, however. Senator Safely says, "Well, it's about time!", and comes running out and trips. He then says, "You've been deliberetly ignoring the very important new child laws I've been trying to pass, mister senate leader sir!". The leader tells him it's because they're all too boring, listing some of the laws he wanted to pass. Safely says it's necessary to protect children because everything is a "virtually virtual death trap". He holds up a yellow book, stating it's a report on what to do about the things threatening children, and that he would read all 60,000 pages to the entire senate. Before even opening the book, however, he gets a papercut and makes a big deal out of it, and is thrown out of the building.

The senate leader says he would, however, give him "eleventy billion dollars" to "research" the safety problem. The other senators laugh as he is thrown out. The senate leader then asks the rest of the senate "who wants to draft a bill outlawing stupid cartoons that make fun of adults?", and the senate members get excited and start waving their hands in the air. Safely meanwhile is outside the door, and calls the others jerks, wondering what he's gonna do with all the money. He finally realizes how much money he actually got, and throws his fist in the air in excitement - only to hit himself in the face.

After the theme song, Numbuh 4 is shown running across the street, yelling to himself, "I'm late, I'm late, I'm late!" He turns a corner and ends up at the park, and is almost hit by a kid falling from the sky. The kid instead hits the concrete floor butt-first. A kid in a referree uniform runs over and measures the crack made by the falling kid, then yells, "15 INCHES!!!" A crowd is then shown, who start cheering. Nick and Chip explain that the kid (named Anthony Davis) is partcipating in the annual "Butt Busting Playground Tournament Finals".

In order to win the tornament, the participants must make a crack in the concrete as large as they can using only their butts. The person who makes the largest crack wins. Numbuh 4 is part of the tournament, and it is later said that he's a 5 time 'butt busting' champion. He finds Numbuh 2, who is his coach for the tournament, and is scolded for being late; his turn is immediatly after a boy named Ziggy Chang, a very large child.

On Ziggy's turn, he has a very elaborate plan he carries out, which eventually has him land straight down from a very tall height. Surprisingly, despite his large size he only manages 8 inches, 7 inches less than the earlier competitor (who was much smaller than Ziggy). Numbuh 4 tries to get concentrated as the announcers say his name, but ends up tripping over his brother Joey. Numbuh 4 is furious, saying that he had told his brother to "stay home with [their] mom".

Joey babbles something, which Numbuh 4 seems to understand because he says, "Okay, fine. You can watch. Just keep outta the way." Numbuh 4 then proceeds to the swing set to start his turn, and is about to go when he gets interrupted by Joey, who is dancing wildly.

Everyone is paying attention to Joey and not Numbuh 4, saying things like, "Aw, look at the cute baby!". While dancing, Joey rips off his diaper. Numbuh 4 gets of his swing and runs at Joey to yell at him, but slips on his discarded diaper and is flung across the playground. He then gets flung back to the swings, then through a tree, then to some other playground equipment. He is repeatidly flung everywhere until he lands though a basketball net face-first instead of butt-first. The referree counts this as his turn, measures the crack he made, and announces he only made a crack that was ".02 micro-millimeters".

Meanwhile, a giant orange safety cone is shown in the distance, and inside is Senator Safely. An alarm is being sounded, and he asks what is going on. A computer says, "Safety scans show activity resulting in serious damage to child buttocks. Recommend immediate action." Safely agrees, saying he's wasted "oodles" of government money on his safety plan, which was now complete, and it was time to take his plan into action.

Back at the playground, the winners are being congratulated, and Nick and Chip talk to Numbuh 4, who was the greatest upset in all of Nick's history of "announcing for parent-disapproved sports", for everyone expected he would win again. He instead lost to a little "sissy" girl. Numbuh 4 insists that the only reason he lost was because of his brother dancing around, and points to his brother, who is dancing again, surrounded by a group of kids chanting, "Go baby, go baby, go baby!" Nick and Chip ditch him to go watch Joey dance, and Numbuh 2 comes over to console him, saying that there's "always next year". Joey again flings his diaper, this time right at Numbuh 4's face.

He throws it to the ground, then lands up slipping on it again. Out of nowhere, a large crashing sound is heard, and everyone stops cheering and dancing. The leader of the Six-Gum Gang shoots his gun, telling Joey to get back to dancing. His gun is then mysteriously covered in bubble wrap, and the shooter is revealed to be a giant robot. As the robot locks on to the other gang members' guns, Lunk whips out a large gum cannon and shoots at the robot. Another similar robot appears, and they both begin bubble rapping every child in sight (including Lunk and his canon). A robot finds Joey (still without a diaper), saying that he was in danger of sunburn and shoots sunblock at him; Numbuh 4 pulls him out of the way, while another child is completely covered in sunblock.

He tells Joey to go home again when Numbuh 2 pulls up next to them in the D.R.A.G.S.T.U.H., and Numbuh 4 hops in. Numbuh 2 tells him to get his brother, and he simply says that "he can get home by himself." He meanwhile sees a robot shoot bubblewrap at Joey, which narrowly misses. Numbuh 4 grabs Joey and they speed out of the park trying to get back to the tree house, all the while Numbuh 4 trying to put a diaper on Joey, telling him to "try to keep it on this time!". They are chased by one of the safety robots, and narrowly miss getting smashed many times.

When the robot is destroyed, and they finally think they're home free, Joey rips off his diaper and starts dancing again. The diaper hits Numbuh 2 in the face, and he drives off a cliff. It turns out they've landed right on the tree house, which is completely bubblewrapped.

Numbuh 2 says worridly that the others are still inside the tree house, and Numbuh 4 searches for Joey under a pile of debris. When he finds him, after being assured that he's alright, he goes from protective to furious and swears he's gonna 'smushamatize' him. Numbuh 2 defends Joey, saying he's only a baby; Numbuh 4 doesn't care and screams at Joey, saying he's been a big pain the whole day telling him to go home, which he does with puppy dog eyes on his face. Numbuh 2 points out that now there are way more than just 2 robots, and they're all heading for the tree house. They grab H.A.I.R.C.U.T.T.E.R.s and rush out to attack the robots.

Meanwhile, scenes of the robots trying to make the town safe for kids are shown, such as kids in a pool being wrapped in extra big life jackets, Rainbow Monkies being de-fuffed because the fur causes "uncomfortable rashes", and an entire amusement park being bubblewrapped. The scene then switches to Senator Safely, who is showing the scenes from above to the other senators, showing how is plan makes the world safer for kids.

No one is impressed, the leader even saying he only enjoys watching the kids running in terror "like monkeys with their butts on fire". The Master Safety Robot tells him that child safety is a priority, and bubblewraps the leader's knife (which he is using to cut a piece of pie). Safely is surprised, because he only programmed the robots to protect kids, not adults. When asking what the robot was doing, the robot replies that there is only one threat to children that had not been destroyed yet: adults.

                                 TRANSMISSION INTERRUPTED

A newsreporter (named Bob) recalls how the Safety Bots trapped every member of the Senate, and how they are bent on destroying anything they deem as unsafe for all children. Another reporter lists some of the things the robots are destroying, such as golf clubs, trains, buses, airplanes, and "anything that can poke your eye out or that moves faster than a snail". The newsroom is suddenly invaded by the robots, one stating they are destroying it because "children are sitting too close to televisions". The scene changes to Joey, who was watching the newscast from an electronic store's window, which was lined with TV's. He starts crawling for home once again, while the Safety Bots continue to capture the adults. One spots Joey on the street and captures him. The scene changes again, this time to Senator Safely walking along a different street lined with bubblewrapped homes, cars, dogs, and children. He complains to himself that "everytime you build robots they end up taking over the world", and vows to get rid of them, when a Safety Bot shows up.

The Safely Bot runs, believing it is after him; it turns out it is actually under attack by Numbuhs 2 and 4. They successfully dismantle it, saying that they've destroyed two, and "only fifty bamillion to go". Safely sneaks up behind them and steals their weapons, saying kids shouldn't play with sharp things (H.A.I.R.C.U.T.T.E.R.s are giant pairs of scissors). They demand them back, since they're their only way to destroy the robots, but Safely claims he has a better way.

The Master Safety Bot is shown in the giant Safety Cone, communicating with the other Safety Bots. Meanwhile, Numbuh 2, Numbuh 4, and Safely travel through the air vents, with Numbuh 4 demanding their weapons back (and Safely refusing). Numbuh 2 asks Safely if he's so "gung-ho" with safety, then why would he want to detroy the robots in the first place.

Safely replies he's only into safety if it doesn't inconvience adults (the robots had taken his car and his golf clubs away). He tells them he installed an override system in the Safety Cone that could stop all the other robots, which happens to be in the same room the Master Safety Bot is in.

As the three of them sneak over to the override button, it notices them, asking if Safely is there to watch the robots make the world safer. Safely tells it he is shutting them down "in the name of adult leisure activities." He hits the button, and the computer asks for a 10 billion number safety code, which he apparently didn't set because he exclaims, "Well, that's new!" The three of them are then bubblewrapped by the Master Safety Bot.

Safely tells the robot that they've gone too far, and it argues that adults are the ones who have gone too far; they are the ones who have created things like loud music and tooth decaying candy that endangers children, and adults are the ones who "allow a baby to roam the streets by itself", and it opens its hand to reveal Joey.

Numbuh 4 confesses that was actually his fault, but the robot silences him. It says that not only do adults endanger children, but the Earth itself as well (natural disasters, poison ivy, etc.). The Safety Bot's final plan is to launch the Safety Cone into orbit and send all the Safety Bots to the Earth and intrap it all in bubblewrap, so that nothing can harm children. It also plans to shoot Numbuhs 2 and 4, and Safely into space since they have proven themselves a threat to children. With that, the Master Safety Bot hits a button and the Safety Cone shoots up for space.

Numbuh 4 asks the robot if he can say one thing to Joey, which it approves sensing no danger. Numbuh 4 goes on to tell Joey he's sorry for yelling at him, and that he actually likes his dancing and finds it funny. Numbuh 2 tells Joey to dance "one last time [for Numbuh 4]", which Numbuh 4 says he was only trying to be nice. Joey starts dancing anyways, which distracts the robot.

Numbuh 4 uses this opprotunity to grab his weapon from Safely and cut himself free, then runs to the robot to detroy it. Joey then throws his diaper in the air like he did earlier, only Numbuh 4 avoids it this time. As the robot shoots bubblewrap at the weapon, it missed and they are flung into the air, headed straight for Joey (who is oblivious because he is still dancing).

Numbuh 4 pushes him out of the way, and the Master Safety Bot raises its hand laser to destroy Numbuh 4 once and for all, because he is such a threat to children. Numbuh 4 then says, still holding Joey, "You're calling me a threat?!? I'm not the one who caused THIS!!!" and raises Joey in front of him to show the robot that Joey has a cut on his right cheek, which is bleeding. The robot denies this, saying as a Safety Bot he cannot hurt a child.

Holding Joey close and crying, Numbuh 4 argues, "Well, you did! YOU blasted the cutters into the air! YOU hurt my little brother!!!" The robot begins to malfunction, because up until this point it has believed it was the only thing protecting the children of the world, almost squishing Numbuh 4 and Joey in the process, which Numbuh 4 points out to him, saying he's surprised all the Safety Bots hadn't "squishified" eveyone. Finally shutting down, and believing it must nuetrilize both itself and the Safety Cone, it wraps eveyone on board in bubblewrap and explodes.

They all fall to the Earth and Numbuh 4's bubblewrap barrier is broken. He is shown still crying over Joey in a crater made by their fall, and the referree from the tournament is shown in the distance, claiming Numbuh 4 had made a crack "eleventy billion inches" long, Chip showing up behind the referree saying that it's a new butt-busting world record. Nick asks Numbuh 4 how it feels to get the title back (as Chip brings the trophy over to him), which Numbuh 4 responds that he doesn't care, because the robot had hurt his baby brother.

He continues to cry when Numbuh 2 comes into view, congratulating Numbuh 4 on his idea of using ketchup as blood on Joey. Dumbfounded, Numbuh 4 stares at Joey, who is waving around a bottle of ketchup, with his 'cut' completely disappeared. Numbuh 4 becomes furious, not believing Joey would lead him on like that. Numbuh 2 clears his throat, and Numbuh 4 instantly pretends like he was in on it the whole time, bragging about how brilliant 'his' idea was.

He points out he also did the same to his knee, and points in a spot on his jeans that is cut, his bare knee red. Numbuh 2 says, "Uh, no, actually I think that's blood." Numbuh 4 gets all dazed realizing it really is blood, and faints. Senator Safely, in the background, pops his arm out of his bubblewrap incasing, shouting, "See?!? I TOLD you someone was gonna get hurt!!!". His incasing, because of the shift in weight, falls over and he yells "OWWW!!!".

Expanded Acronym: Evidently Not Getting Language Annoys Nigel Desperately
When Numbuh 1 is taken to England, someone gives him a book, resulting in Numbuh 1 getting followed by 3 kids. A precursor to "Operation: Z.E.R.O.".Numbuh 1 and his father are aboard a plane, going to his old homeland England for a visit. Numbuh 1 complains to his father but his father says it would be a experience. A boy next to him, named Trevor, reveals himself as being on a mission to return a book to where it belongs. Numbuh 1 wants to know more about it but Trevor says not until they're out of the plane. At the airport, Trevor becomes frightened and gives the book to Nigel telling him to meet with him at the Great Library at midnight. A boy in a black suit with a umbrella asks for the book and Nigel refuses and runs from the boy. His father says that two minutes and he already made a friend. The umbrella boy uses the umbrella as a rocket but crashes.

Numbuh 1 meets a girl with four long scarves wanting the book. Numbuh 1 realizes a lot of people want the book and flees. The girl uses the scarves like tentacles. Numbuh 1 is confronted by more kids and is eventually saved by a limo. Three kids are in the limo. Numbuh 1 says he's glad that Sector E is on his side. The group laughs and later, into the night, go to a soda bar. The leader of the three tells a British joke where everybody laughs except Nigel, due to him not understanding the 'language.'

Soon, the ones who try to steal the book come and Nigel escapes to the sewers. Numbuh 1 finds Trevor and they enter the Great Library. The book is The Book of KND explained by the enemies and a lot of people would want their hands on it. Nigel hands the book to his bar friends and than discovers that the others are the KND and the ones who Nigel gave the book to are actually the Rowdy Hooligans from Across the Square, who are working for Father.

They open the package containing the book and find that it is not in fact the Book of KND, but a Rainbow Monkey book, "Rainbow Monkeys' Tea and Crumpets Picnic" to be exact. Trevor grabs it from the Rowdy Hooligan who was holding it and races toward the library's book return slot, but before he can reach it, it closes.

Sobbing, Trevor reveals that he needed to return the book before it was overdue, and that now he will have to pay the fee of 25 pence. (50 cents in American count.)

Later, the Rowdy Hooligans and Sector E decide to go to the soda bar. Numbuh 1 asks Sector E why they aren't going to fight. Sector E's leader, the umbrella boy, wonders why he would think they would fight over a Rainbow Monkey book, then adds, "What do you think we are—Americans?"

Nigel, at the bar with his father, tells a British joke. Everybody laughs at this. Numbuh 1 confesses that he had no idea what he said.

Expanded Acronym: Attack Will Amazingly Ruin Dinner Show
Sector V attempts to sabotage the Villain's Choice Awards. A parody of Nickelodeon Kids' Choice Awards and Ocean's 11.The villains are holding their annual awards show to reward the best villians throughout the year. So naturally, it's up to Sector V to ruin the show. Numbuh 1 comes up with a highly intricate plan. He tells the rest of the team to meet up with him at the bottom of a dormant volcano at 20:00 (8:00 PM) in order to put the plan into action. When he fails to show up, the team decides to go on without him. The team goes into the place and listen to the "cheesy" opening for the villain choice awards. Numbuh 2 then explains the plan.

Numbuh 4 beats up Knightbrace in the bathroom with the S.P.L.A.N.K.E.R. and disguises himself as Knightbrace. Numbuh 4 will take Knightbrace's place at the table where Toilenator and Count Spankulot are sitting. Numbuh 5, disguised as a waiter, places lasagna, one with lots of garlic, for Numbuh 4 and Count Spankulot for dinner. Count Spankulot chokes on the garlic because he is allergic to it, and Numbuh 3, disguised as a doctor, uses the Heimlich maneuver to make him hack the garlic up, which will make the garlic hit a cymbal in the orchestra pit. This will, in turn, make the conductor and musical group interrupt Mr. Boss's emotional speech. Numbuh 5 disguises herself as a stage manager. Mr. Boss complains at her for starting the orchestra during his speech, giving Numbuh 5 the opporunity to take the key to the lounge room, which Mr. Boss has responsibility for. Numbuh 4, still disguised as Knightbrace, attaches the red wire to the envelope for 'Villain of the Year'. The red wire is disguised by the catering cart. Numbuh 5, disguised as a waiter again, runs the catering cart while avoiding hungry villains into the parking lot. Numbuh 2 will attach the red wire for 'Villain of the Year' into the Common Cold's vehicle, which is filled with Snot-Bomber dynamite. The Sector V operatives, except for Numbuh 1, go home and watch the show.

However, Robin Food, the host of the Villains' Choice Awards says to every villain that the winner's trophy is Numbuh 1.

Numbuh 4 suggests that they should just grab Numbuh 1 and run away, but Numbuh 5 says that the villains would see them. Numbuh 4 says that the nominees for the 'Villain of the Year' award are Father, Gramma Stuffum, Stickybeard, and Mr. Boss. Then, Sector V runs onto the stage, grabs Numbuh 1 and runs away.

Father, Gramma Stuffum, Stickybeard, and Mr. Boss get into a fight over who was going to win the award. Mr. Jelly, or Knightbrace without his disguise, comes onstage and opens the envelope, setting off the bombs on the Common Cold's ship and preventing everyone from finding out who won the award.

After having escaped, Sector V takes off Numbuh 1's gag, only to hear him complain about how hairbrained their rescue plan was. Numbuh 5 replaces the gag, complaining about being stuck with Numbuh 1 even though they weren't nominated for the award.

Expanded Acronym: Recreation Ended 'Cuz Enemies Savor Salad
When salad oil is discovered in the school playground, Numbuh 1 must find a way to save recess, while still keeping a promise to Lizzie. Principal Smelling and his assistant somewhat parody Klink and Burkhalter in Hogan's Heroes.n the beginning of the episode, it shows Numbuhs 1, 2, 4 and 5 walking through the school's playground, commenting on good things about the perfect recess day. Numbuh 5 happily adds that Numbuh 3 is having fun, too, catching Numbuh 4's attention. The Kid is pushing her on the swing. Numbuh 4 pushes him out of the way, saying he's doing it wrong, and pushes her really hard. When she swings back, she rams into him, he then lands on concrete, causing it to split open, spewing, to Numbuh 1's confusion, salad oil.

In the next scene, the students would rather stay inside and learn random things than go out for recess. Forced to leave the classroom, they go outside to show equipment to look like a playground, only that it makes salad oil when they use it.

Numbuh 1 is seen in the pricipal's office, promising Lizzie that he would go on a date with her if she let him listen in on the principal's conference. He overhears them mentioning that they were going to make all of the schools' playgrounds into a salad oil making facilities. Back at the treehouse, they are all getting ready for the mission, when Lizzie abruptly arrives, yelling at Numbuh 1 for forgetting their date, again. Lizzie mentions a romantic movie she wants to see with him, and it makes Numbuh 3 excited, wanting to go see it. Giving Numbuh 5 an idea, she dresses Numbuh 3 up in a Numbuh 1 costume with the V.O.C.A.L.-Y.O.K.E.L..

Numbuh 3 gets busted when she lets out a tear, which lands on the device, shorting it out. This convinces Lizzie that Numbuh 1 has sent another robot on their date. When the team is just about to ambush on the "We Hate Kids Conference", Lizzie barges in, wanting an explanation. Numbuh 1 gives an emotional speech about kids deserving recess, hoping to ease her up. Only, he adds that if she really wants him to go on the date instead, he would. Lizzie starts to cry, making him think he won and could finish the mission. She says he made her happy and that she forgives him with the robot fiasco, only that they are going on the date right then.

Some of her mucus falls in the meeting and lands on one of the principal's salads. He then shouts out, rather hastily: "This salad oil tastes like boogies!". This immediately causes the other principals to leave. Shortly after, it cuts to the ending scene, in which Numbuhs 2, 3, 4, and 5 and stolling through a normal day of recess. Numbuh 5 notices and points out Numbuh 1 swinging Lizzie on the swings. Numbuh 1 notices them, and starts to talk about how the mission was a success, and Lizzie rams into him just like Numbuh 3 did to Numbuh 4. He hits the concrete and, much like before, a substance spews out of it, only this time, it it prune juice.

Numbuh 1 wakes up to discover that he is the president of the United States in another reality, who is about to sign the Declaration of No Kids' Rights.Numbuh 1 wakes up and walks into the bathroom, looks into the mirror, and sees he's an adult. He screams and an adult version of Numbuh 86 and Chad, and well as other guards, run in. One of them asks "Are you okay, President Uno?" Numbuh 1 begins to panic, saying there was some mistake; he wasn't the president. Adult Numbuh 3 then appears, and calls in a team of stylists (Numbuh VO5 and Eggbert) who put Numbuh 1 in a suit while he asks adult Numbuh 3 whats going on. She says that she's trying to tell him and rushes him off to a press conference. Once there, reporters begin to question him about "the war against the hated Kids Next Door" (Nick) and about the signing of the Bill of No Rights for Kids. Adult Numbuh 4 then pushes him away from the podium and tells the reporters about the plan to get rid of the KND. Numbuh 1 again panics, say that they were all KND operatives; adult Numbuh 3 then draws attention to Numbuh 1's hair and shoos him out. In the hall, they then run into adult Numbuh 2, who is the Vice President. Then they walk into the Oval Office, and Numbuh 1 discovers he has a son named Shirley. Shirley both looks and acts like a Delightful as Kuki explains his wife wanted a girl. Lizzie then bursts in and reveals herself to be Numbuh 1's wife.

He is then confronted and asked to sign the Bill of No Rights for Kids, which Numbuh 2 claims will get rid of the KND. Numbuh 1 asks what they're going to do to them, and Numbuh 2 says it's better he doesn't know. Numbuh 1 then goes to the bathroom, and escapes out the window. After a few minutes, the others begin to worry about him, and the security guards break down the door to find him gone. Numbuh 4 then send the army to look for him. Numbuh 1 runs till he find Sector V's Treehouse, and easily avoids the security system. Then he is attacked by unseen KND operatives; he grabs a weapon from under the floor and beats them, but hits his head and passes out.

When he wakes up he hears the KND trying to find out how he got in. Then another operative appears, asking who broke into their treehouse, Numbuh 5000 replies "It's your dad, sir.". Numbuh 1 is then shocked to see that it's Shirley, now looking like the 10-year-old Numbuh 1 with red hair and blue eyes. He calls him Shirley, and he angrily replies that he goes by Veego. Numbuh 1 laughs, saying he would of been better off with Shirley, and the rest of Sector V laughs. Shirley/Veego then tells him to call him Numbuh 1600. Numbuh 1 then tries to explain who he is and what happened. Numbuh 1600 doesn't believe him, saying his dad is a "kid-hating adult, who's on the verge of signing a bill that would take away the rights of every kid in this country.".

Just then Numbuh 4 and the army are shown to of surrounded the treehouse, and Numbuh 1600 blames Numbuh 1. Numbuh 1 begins to make a plan, but Numbuh 1600 stops him, calling him a jerk. Numbuh 1 then shaves his head and then begs them to believe him. They don't and two of them take him away. A minute later, Numbuh 5000 saves him, saying he would take him to Numbuh 5, explaining she's his mom.

Numbuh 5 is in a jail for the criminally childish and seems to have gone insane. She yells at Numbuh 1, saying he put her here so she couldn't tell anyone he used to be in the KND. He tries to explain that he's "not that Nigel" and she begins questioning him about the KND. As she is finishing, Numbuh 2 and the security show up and begin to take him away, Numbuh 5 tells him the Washington Monument can take him home. He then goes to the bathroom and tries to escape again, but some of the windows are being guarded. He then hears banging outside, and Numbuh 1600 enters, saying he believes him because nothing could have made his real dad cut his hair. Numbuh 4 shows up and Sector V use a L.E.M.O.N.A.D.E. on him.

Numbuh 1 and Sector V go to the Washington Monument and enter into a door. Numbuh 2 is inside and tells him it can take him home. He says he'll let Numbuh 1 go if he signs the Bill of No Rights For Kids. Numbuh 1 refuses and Numbuh 2 kicks him out. Numbuh 4 and Numbuh 3 show up too, and tell him to sign the bill. Numbuh 1600 then tells him to sign it and go home, that they would be okay. Numbuh 1 still refuses, saying "I'll never betray the Kids Next Door, even if I am an adult.". Numbuh 4 then orders the Army, Navy, Air Force, marine animals, and shunky scouts to attack Numbuh 1. But when the missiles hit, Numbuh 1 emerges unharmed. Finally getting it, he then undergoes a Hulk-like transformation, fit with a mohawk. He then begins tears up his foes, before they start piling on him.

He wakes up in the Moonbase hospital and a doctor says he's only been out for about ten minutes. Numbuh 1 then says "It wasn't a dream, it was more than that, some kind of test." They then leave the room. Two shadowed figures are then seen discussing what just happened, saying Numbuh 1 preformed well, but to stop using Chester's Happy Headband so Numbuh 1 won't catch on... yet.

End Credits: Numbuh 1 is explaining the dream to Sector V, ala Wizard of Oz, complete with black and white color. He then asks why they're all staring at him, and it shows him dresses as Dorothy, complete with Toto. He screams like a girl, wakes up, and says "Man, I've got to stop watching those stupid old movies

Expanded Acronym: Salad Pushing Invaders Now Attempt Crusade Here
Amerigo Vespinacho tries to spread spinach throughout the school, and it's up to Sector V to stop him. A parody of the Spanish Armada and the Spanish Inquisition.The show begins with the king of Vespinaccia sending an emissary to America to spread the word about the glory of spinach. The first to meet them are Numbuhs 2 and 4, who are celebrating "Ditch school and go to the beach day", which Numbuh 4 states he made up. Numbuh 2 is captured and Numbuh 4 runs to the school to warn of the approach of the Spinach Armada, but is too late, as Vespinachio enters the wchool behind him and offers spinach to all the children. When Numbuh 1 and the other Sector V operatives attempt to fight back, they encounter a huge army of Vespinaccians outside and are captured. Wally however, is not captured because of his escape route malfunctioning and trapping him in a locker. He finds a Spinach monk passing by and grabs him to steal his robe and flee the school, but finds it is Numbuh 2, who has been converted to the way of Spinach. Numbuh 4 is promptly captured, as Numbuh 2 walks away, chanting contently to himself.

Numbuhs 1, 3, 4 and 5 are then seen held in a chamber, similar to the torture chambers of the Spanish Inquisition, in which various devices attempt to force them to eat Spinach. As they are tortured, the Spinach Inquisitors break into a musical number as they force the kids in various creative ways, including dunking Numbuh 1 in a vat of spinach and tying Numbuhs 3 and 5 to a board and force feeding them. Suddenly, Hoagie screams for the song to stop, saying that if children don't want to eat spinach, they should not be forced to. Vespinaccio sees this as heresy and a duel between him and Hoagie begins, ending when Vespinaccio falls into his own vat of spinach. As he struggles, he proclaims that he himself does not like spinach, and only pretend to to please the king. It is also revealed that none of the inquisitors like spinach either. Hoagie agrees to rescue him, but under one condition.

Later, the Vespinaccians and the Kids Next Door sign a treaty agreeing that in return for saving them, the Vespinaccians will never force children in their country to eat spinach ever again. Instead, they would try in Canada. We also learn that the king himself doesn't like spinach, and he only makes others eat it so he does not have to.

With Father away for the day, The DCFDTL invite Cree and the teenagers to their mansion to plan a new strategy against the Kids Next Door, but instead, the teenagers turn it into a wild house party, leaving the DCFDTL to call Sector V for help.The episode begins with Father leaving to Saratoga Springs on order from his doctor. Apparently, he's in need of rest and relaxation after causing too much adult tyranny. He entrusts the Delightful Mansion to his children, who promise to be good. With a final reminder to feed the cat, Father is off to enjoy his mini-vacation.

However, as soon as Father leaves, the Delightful Children contact Cree to confirm that he's left. Turns out that they had been planning to throw a party for the teens along with Cree to plan the destruction of the Kids Next Door.

Meanwhile, back at Sector V headquarters, Numbuh 1 is discussing the Kids Next Door scientists' analysis on a multitude of items stolen from Cree's room. As Numbuh 4 helps himself to some unmeltable Pacific Breeze flavored ice cream treat, Numbuh 5 comes into the room and scolds the rest of the team for stealing from her sister's room.

However, before Numbuh 5 can continue chastising the rest of her team, the Kids Next Door Help Me Hotline goes off.

Much to their surprise, it turns out that the Delightful Children are calling this time.Back at the mansion, the party isn't going quite as the five Delightful Children had planned. Cree and the rest of the teens never wanted to actually plan the destruction of the KND. They just wanted to use the Delightful Mansion to throw a real, wild party, complete with loud music and soda.

After the Delightful Children make attempts to qualm the party, Sector V shows up, wanting to know the reason why the Delightful Children would summon them to their rescue. After the Delightfuls explain the situation, saying that they need to get them out of the mansion before Father comes home, Numbuh 1 declines, claiming it not to be his problem. However, Numbuh 5 agrees with the Delightful Children when they say that it's the Kids Next Door's job to rescue kids, no matter who they are. So then Sector V agrees to help, begrudgingly.

Numbuh 2 comes up with a plan. They decide to flood the teens out by rigging the sprinkler system in the house with instant mashed potatoes mix. Numbuh 3 and Numbuh 4 are assigned to making their way into the kitchen to get the potatoes and Numbuh 2 and Numbuh 5 are sent to find the sprinkler system, which is located in the basement of the mansion.

Cree, dragging Maurice along, sneaks into the basement, which is where the Delightful Children say that Father's 'inner sanctum' is located. Numbuh 5 figures out that something is obviously up, and decides to follow them.

In the mean time, Numbuh 3 and Numbuh 4 have to slow dance through a room, much to Numbuh 4's chagrin. After successfully making it through the room (but not without running into Chad), they find themselves in the kitchen and find the spuds.

Down in the basement, Numbuh 2 and Numbuh 5 find the sprinkler system. Numbuh 5 lets Numbuh 2 do all the pipe work as she runs off to find out what her older sister is doing lurking around in the basement of one of the most evil villains they know. She runs into Maurice, who questions her presence at the party. She, in turn, asks him what he's doing down there. Of course, their goals are both one in the same: finding out what Cree is up to.

Cree calls Maurice in the middle of their conversation, interrupting them. She leads him to Father's 'inner sanctum'. But she didn't want to steal anything...other than a kiss from Maurice. Maurice, somewhat shocked at her romantic advances on him, tells her that she stinks, to which she mentions her deodorant being missing. Numbuh 5 steps in after her sister explains her stickiness, agreeing that she, indeed, stinks.

However, before Cree can do anything to get back at her sister for embarrassing her further, one of the teens runs in, saying that Father is just down the driveway and that everyone needs to get out.

The teens flood out of the house as Father pulls in the driveway after his relaxing day. He is more than shocked to see the plethora of teens pouring from his mansion.

Since the teens left, Sector V's mission is complete, and the Delightful Children from Down the Lane thank them for their assistance, for once. Numbuh 1 tells Numbuh 2 to hit the abort button, to which Numbuh 2 says,"What abort button?", since evidently, there was no such thing.

Seconds later, the house, already in a shambles, is explodes with mashed potatoes. Father, shocked, sees the Delightful Children fall into the potatoes. He yells at them briefly for throwing a party without permission, but then Sector V lands next to them in the mess, and the Delightful Children pin the blame on them instead.

Numbuhs 3 and 4 are launched into space to break the "Ridiculous" space barrier, but black out in mid-flight and wake up on a world ruled by anthropomorphic, talking Rainbow Monkeys. A parody of the first Planet of the Apes movie (also note the title of the operation).The scene starts in KND Moon Base where Numbuh 74.239 is briefing Numbuh 3 and Numbuh 4 on a special trip that is supposed to take them out of the solar system. They pan onto the screen, Numbuh 3 eating popcorn and Numbuh 4 standing there with an annoyed look on his face. They're in a room full of operatives waiting for the historic mission. Before the mission starts, Numbuh 2 takes Numbuh 4 aside to tell him to tell Numbuh 3 his "secret". Numbuh 3 and 4 then take off, and seem to be knocked out by the G-forces. When Numbuh 4 wakes up, he is sitting next to a lake. The spaceship that brought him there sank into the lake as he wakes up. He notices Numbuh 3 is missing, and follows her footprints to find her. Shadows in the high grass around him start chasing him and attack him. When he wakes up, he is in a room with Professor Snuggles and Mrs. Wubsy Tubsy, a pair of living Rainbow Monkey scientists. They ask Numbuh 4 a series of question to try to understand his psychology, and infer that they have found a boy. General Hugs breaks in on their meeting and tries to take Numbuh 4 away for being a boy, claiming that boys stand for everything that goes against Rainbow Monkeys. General Hugs puts Numbuh 4 on trial, and gets Numbuh 3 to testify against him. Because of her aloofness, she says all the wrong answers, and the court rules that Numbuh 4 needs to be hugged to death. Numbuh 4 distracts the Rainbow Monkeys by throwing a flower the other way. He grabs Numbuh 3 and runs out of the courtroom, with the other Monkeys in-toe. After running a distance, Professor Snuggles and Mrs. Wubsy Tubsy usher them outside to a Spaceship they have evidentally assembled for Numbuh 3 and 4s' escape. The mob of monkeys come over the horizon as they ascend into the spaceship. After the blastoff, Numbuh 4 tries to tell his secret again. However, they land again before Numbuh 4 can say anything. When they come out of the rocket, they find that they really did not go anywhere and the mob of monkeys is there. General Hugs starts to approach them, when suddenly, he keels over in some kind of digital meltdown. A man comes out from behind it and kicks it, saying, "Stupid Animatronics." He explains to the kids how they're just in an amusement park, which had just closed. As they leave the park, Numbuh 4 finally tells Numbuh 3 the secret, which is just that she has a kernal stuck in her teeth from the popcorn she was eating earlier. They walk off, Numbuh 3 complaining that she had to go through the whole day looking like that, and Numbuh 4 complaining that he is the one that always has to tell her these things.

Sector V sends Numbuh 2 into hiding at an Amish sector to his extreme dismay.After losing a contest at the Kids Next Door 2x4 Technology Convention to Sector F, Numbuh 42 gives Numbuh 2 his invention, Tree House Seeds. They start to talk about a “Doctor Time Space in the Continuums” marathon when the rest of Sector V shows up. Suddenly a green, caterpillar-like machine comes to take all of the scientists at the convention, including Numbuh 2. He takes out his invention, I Can’t Believe It’s Not Booger, so it would lose its grip on him. After it works, all of Sector V run to their S.C.A.M.P.E.R.They believe that the attack was ordered by "The Splinter Cell," an organization whose goal is to “permanently wipe out all adults”, and think that Numbuh 2 should stay with Sector A for a while to stay safe. Once there, Numbuh Jebadiah, Sector A’s leader, informs Numbuh 2 that 2x4 Technology isn’t allowed. That alone makes him beg Numbuh 1 not to leave him. After introducing Numbuh 2 to Numbuhs Ezekiel and Rebecca, Numbuh Jebadiah orders him to dress like them and wear a fake beard. He then shows him their tree house, which is still only a shrub.

Later, when Numbuh 2 starts questioning why Sector A doesn't use any 2x4 Technology, Numbuh Jebadiah states that it's better to work with one's own hands than the "lazy" use of machines. Feeling insulted, Numbuh Two pulls out a seed derived from years of hard work by the KND and plants it in Sector A’s outhouse, causing an advanced KND treehouse to instantly grow. Right as that happens, the caterpillar-like machines burst out of the ground. When Numbuh 2 tries to save Numbuh Rebecca from one of the machines, she tells him that she’s going with them and that he is too. One of the machines come up behind them and Numbuh 42 greets them from inside of it and it is revealed that they weren’t the Splinter Cell all along; it was just a group of operatives who wanted to watch the “Doctor Time Space and the Continuums” marathon without being made fun of by the other kids.

Expanded Acronym: Guess It's Realistic Lizzie Finally Realizes Its Essentially Nigel's Dysfunctions
Lizzie Devine thinks Nigel has found a new girlfriend.The episode begins with Numbuh 1 on the communicator/phone with his girlfriend, Lizzie Devine. After they talk and Lizzie reminding Nigel not to be late for the wedding the two will go to, the computer wraps around his ear and tells him the coordinates of a bank heist at the Candy Bank and that they need him to get on the mission ASAP. Numbuh 1 checks his watch and sees that he has enough time to finish the mission and be at the wedding on time. His car transforms into an airplane and flies off to the coordinates given by the computer. After the introduction and theme music, Stickybeard and his crew blast their way into the bank of sweets. He then opens the vault and takes the Sweater of Sweetness. The scene switches to Numbuh 1 who's heading to the bank right now. He catches up to them and snatches it away while driving away. Satisfied, he calls Moonbase to tell them the mission was accomplished though Stickybeard and his crew shoot at his phone and him, shouting at him to give it back to them. As the chase goes on, Numbuh 1 leads Stickybeard and his crew under and over bridges which causes the ship to fall apart until Numbuh 1 stops and sits casually at a table with the sweater in his hands.

He watches as Stickybeard and his crew abandon ship but instead, they fall out of the ship leaving a satisfied smirk on Numbuh 1. Numbuh 65.3 comes around the corner and praises his mission for being a success and puts the sweater in his backpack. Numbuh 1 asks him to join him for some lemonade, though Numbuh 65.3 looks a bit nervous as he leaves. He tells him he has to go and to say hi to Lizzie for him to which Numbuh 1 spits his lemonade out as he had forgotten he had to meet Lizzie at the wedding. Minutes later, Numbuh 1 arrives at the church altar and Lizzie turns to him crying and asking how he could've left her at the altar.

                                      TRANSMISSION INTERUPTED

Lizzie later reveals that it was for her sister's wedding and she starts to yell at him because he ran off for a mission. She then says that he left her like some dateless loser and Numbuh 1 says he'll attend her brother's wedding but she states that he's only four. Seconds later, the computer urgently requests Numbuh 1 to get a move on for something important to which he stutters to Lizzie after their fight. He then says he has to go and Lizzie threatens that if he leaves her again and embarrasses her again, but Numbuh 1 says he'll be back just in time for the wedding reception.

The scene changes to the Moonbase where the computer introduces. Numbuh 1 lists a couple of problems then the computer reveals that it was only Meatball Sandwish Day. Nigel starts to complain on how the computer brought him up there like that but the computer argues that he missed the last one and that he told it to make it urgent for him to know every Meatball Sandwish Day. As he was about to make another point, Numbuh 362 appears and greets him to which Numbuh 1 saluts his Surpreme Leader.

Rachel then tells him to lay off the formalities and asks him to join her for some meatball sandwiches. Nigel stutters as he says he has to be somewhere [with Lizzie back at the reception] but she playfully threatens him after flicking him on the stomach to "not make it a direct order." Nigel smiles and follows after her and joins her though she places a hand on his shoulder and brings him close to whispers, "what's going on?". Rachel tells him that there's a "KND Splinter Cell" in the Kids Next Door. She gives him information about it and they pass Numbuh Change for a 20. Numbuh 1 asks her what they want with him and she answers that maybe they want him to join them. He tells her that he was approached by Numbuh 65.3 and Numbuh 362 mentions that the bank never got the Sweater of Sweetness back. Numbuh 362 brings him closer to tell him that anyone of the operatives in the cafeteria or in the Kids Next Door could be in the Splinter Cell. Then they plan to pursue Numbuh 65.3 though once Rachel mentions "reception" Nigel spits his sandwich out and slaps his face as he rushes back on Earth to rejoin Lizzie.

Once back on Earth, Nigel smiles at Lizzie though she complains that the reception is practically over and asks where he went. She smiles after he tells her that he was "tied up" and she gives him a cake to which Nigel says that he wasn't really hungry. Lizzie questions him and spots tomato sauce and he tells her that he ate before he came. She becomes angry at him and starts complaining about his "big butt" though he grabs Lizzie and tells her that: "Shut up and let me say I'm sorry." Lizzie's eyes tear up as they dance while Nigel apologizes about the recent events from earlier. Then someone taps in and Numbuh 1 gets a message that it's Numbuh 65.3. He then pummels "Numbuh 65.3" but Lizzie scolds him that it was her grandmother. Nigel gets a call from Numbuh 362 saying that she got a track on him and he tells her that the computer told him it was at the reception. Then Numbuh 362 informs him that he has to grab whatever he needs to go with her to chase him down. He gets nervous because Lizzie is getting ticked by the minute but as he sees Rachel at the driveway, she orders him to move it and he looks back but he gets in the car and Lizzie follows and saw Nigel jump in the car with Rachel. Lizzie then gets hit in the head with a cast iron bouquet.

Lizzie wakes up to see her sister and her brother-in-law and ask if she's alright. She dreamt she saw "her Nigie jump in the car with another girl" to which they answer he did. Then the camera guy offers to show her again and where Numbuh 1 beats the "stuffing" out of her grandmother. She growls then storms away to try and find where he went.

The scene changes to Nigel and Rachel as they are in hot pursuit of Numbuh 65.3. Numbuh 1 wonders why he's heading to an airport and Numbuh 362 points out that he knows all KND flight patterns and that Global Command can track him down. They come to a conclusion that he is hiding where he is going probably to the Splinter Cell Headquarters.

Lizzie appears at the Treehouse in Sector V and demands to know where he is, as she saw him with another girl and threatens to find the two. However, the computer argues with her then traps and captures Lizzie.

The communicator on Nigel's ear wraps around as he demands who's calling him as he's running with Numbuh 362 still in hot pursuit of Numbuh 65.3. It turns out to be Lizzie as she complains about the Treehouse trapping her though sounds make it convincing that Lizzie is in trouble as the line goes dead. Rachel demands what's wrong with him then they start to argue about his priorities. She then gives him a direct order as Surpreme Leader and she tells him "that you have better get your priorities straight!" to which Nigel answers back, "I am." He leaves to save his girlfriend leaving a hurt look on Numbuh 362's face. Nigel appears at the treehouse demanding to know where his girlfriend is to which she is trapped in a bubble made by the computer. Lizzie complains about all the things that happened today to which he answers he'll answer later. He tries to find a way to get her out though the computer shoots at his feet. He demands why the computer won't release Lizzie to which it replies that "Lizzie is not the one for you" where Lizzie and Nigel look at each other like it's crazy. Numbuh 1 demands why and it answers that they are perfect for each other (Numbuh 1 and the computer) because: both are loyal to the KND, both love to watch Yipper cartoons, and that both don't have hair. Numbuh 1 laughs and says it is just a practical joke but the computer says it's not and he replies that he's a human and it's a machine. Lizzie threatens to smash the computer but the bubble is closing in. The computer states that Lizzie is obsolete and he throws his communicator and destroys the containment. Nigel gets her out but Lizzie complains at him not to "butter her up" but they run and go to the car-airplane to run away. Lizzie calls him "cheater-mc-cheater pants" and then the computer goes after them as the Treehouse stating that he can't escape "true love." The computer traps Nigel and Lizzie at the cliffside and he argues with the computer that they aren't compatible because he loves Lizzie. The computer comes to a conclusion that if it can't have him then no one can. It grabs Lizzie first then Numbuh 1 and initiates a self-destruct sequence in ten seconds. Lizzie yells at the computer that she can have him because: he doesn't remember her birthday, doesn't give her flowers, spies on people that shouldn't be suspicious, and doesn't hold her hand in public. The computer self-destructs after Numbuh 1 takes Lizzie from the Treehouse's grasp and saves her. He says her plan was brilliant in distracting the computer with her speech. However, Lizzie tells him that she meant it all and says that he wants to save kids everywhere while she wants a stable boyfriend who would pay attention to her more and won't have "their treehouses explode." She tells him she's done and leaves crying while Nigel calls after her shouting that he can change and everything to try and get her back. Seconds later, Numbuh 362 drives up and asks if he needs help saving Lizzie to which he responds that it's alright and that they broke up. After hearing they broke up, Rachel felt sorry for him, looking away from him.

She assured him that Numbuh 65.3 wasn't part of the KND Splinter Cell, but instead was trying to sneak the Sweater of Sweetness into a Fat Camp his parents were sending him to. In a subtle way, Numbuh 362 asks him out to dinner to try and comfort him though he rejects. Once he gives her his answer, she jumps in her vehicle and puts her head down and gives a comment that says she'll be there for him when he needs her and leaves with a disappointed look on her face. After she leaves, Numbuh 1 looks out to the night sky and two mysterious shadows say that he's ready with his connections severed.

Heinrich uses a ritual involving sacred golden caramels to take away the qualities the Sector V operatives value the most. (Numbuh 1's leadership, Numbuh 2's intellect, Numbuh 3's giddiness, Numbuh 4's toughness, and Numbuh 5's Coolness) Numbuh 5 eventually teaches Heinrich that he needs to share his candy to revert to his original form, she is then seen leaving with a young Blonde girl (Which, disturbingly, is implying that Heinrich was a girl before the transformation.)In Operation: C.A.R.A.M.E.L. the incident in Guatemala 5 years ago between Numbuh 5 and Heinrich Von Marzipan is explained. In this episode Heinrich wanted to create ancient golden caramels and the way to do so was to use a magic ritual to sacrifice the most valued quality of a human victim and once done it turned their quality into five pieces of delicious caramel sweets with the flavor depending on the unique quality of the victim. Using his own quality he created the caramels and Numbuh Five knowing he couldn't control his greed left him behind, and after Heinrich ate all his candy he assumed there was no way to restore his true self and he blamed Abigail for it.

Five years later he tricks Abigail into a truce and he uses the ritual to steal her quality and he does the same to a number of KND operatives. Later he begins to taunt the now nerdy and pathetic Numbuh five and eats all her caramels except one but before he eats her last one Numbuh 5 reveals that she had Heinrich's last caramel all these years and was waiting for him to learn how to share his candy, but in a blind fury he pushes her out of the way and takes his caramel and almost eats it, but after Abigail reminds him of how he used to be and how much she cares about him he is driven to tears and gives her back his caramel thus ending the curse.

After finding out that sharing their caramels will break the curse everyone is turned back to normal and at the end of the episode it is revealed that Heinrich is really a beautiful young girl named Henrietta Von Marzipan who is Abigail's best friend and her former candy hunting partner, and in the end their friendship is restored and they bid each other farewell, but Sector V remains grossed out by the revelation, except Numbuh 4. When Numbuh 1 explains, Numbuh 4 freaked out

Adults send Numbuh 4's family to the Moon to colonize it. But Sector V diverts the colony to Hollywood, where they stage a fake colonization, tricking the Beetles family and the adults at mission control to prevent them from discovering the KND Moonbase. A parody of The Truman Show.The episode opens with the footage from the 1969 moon landing. Sector V, excluding Numbuh 4, laugh their heads off watching this. Just then, the news announces that NASA intends to colonize the Moon by sending a family up there, taking them by surprise. Up on the KND Moonbase, Numbuh 362 informs all operatives that since the KND Moonbase was established, the KND pulled off a fake landing and that they will have to do it again because the adults are sending a family (Numbuh 4's) to the moon to see if it can be colonized, but the Kids Next Door redirect them to Hollywood, making the Beatles family and the adults think they're on the moon when they aren't, so they won't discover the KND Moonbase. And the best part is, they haven't even told Numbuh 4.

The Kids Next Door try to make the Beatles stay on the Moon as short as possible. Meanwhile, Numbuh 4 is grumbling over having moved to the Moon and leaves the dinner table in a fit with his father. He then thinks to go to the Moonbase and escapes from his house, unaware that he's walking to the edge of the set, with his family following him. In desperation, Numbuh 1 issues the ok for the KND to attack the Beatles disguised as aliens, sending the Beatles fleeing back into their house and returning to their original home with an emergency button. But in the process, they make the adults fire missiles at the real moon, trying to destroy the 'aliens'. Numbuh 3 then came up with a brilliant plan to divert the missiles away from the moon, and fake the moon blowing up. Then there is a screen, in which the adults were watching. Showing Numbuh 3 holding a dart, pointed at the balloon that was on her blue Rainbow Monkey, causing it to pop. In the end, she ended up sending the missiles towards the fake moon in Hollywood. The episode then ends with Numbuh 5 saying, "Houston, we've got a problem!"

Expanded Acronym: Teens Readily Extend Armistice To Youngsters
The KND and the Teens are about to sign the "You don't mess with us-We don't mess with you" Kid-Teen treaty. It is going to be signed by Numbuh Infinity (KND) and the Teens' leader, but it turns out to be a trap for the KND, making Numbuhs 1 and 274 set out to prevent it after being falsely convicted by the KND.In a flashback, Numbuh 1 is given his entrance exam into the Kids Next Door. Once he exceeds beyond expectations, he is congratulated by Numuh 274, who shows him the "shoes-tied-together" trick, the oldest one in the book. After that, Numbuh 8 by 10 takes a photograph of the two shaking hands. In the present, the teens and kids set up a treaty to end their feud. While thinking about the possible peace, Number 1 hears shouts in Numbuh Infinity's room. Inside, Numbuh Infinity and the teen leader Chad, are fighting and other KND kids rush in and Numbuh Infinity tells them to arrest Numbuh 1! While being transported to KND Antarctic Prison, Numbuh 1 escapes and suspects the treaty is a trap. This is confirmed by Chad who admits that it was trap. Chad then sabotages the prison ship and is forced to drag Num 1 along, since they're handcuffed to each other. They arrive at a mini-mart in the middle of nowhere, which Chad reveals is actually a teen base. Discovered by the other teens, angry that Chad showed Numbuh 1 their hideout, Chad and Numbuh 1 commandeer a bike to fly to the treaty.

All kid and teen agents meet up on a giant floating platform were the trap is sprung, as the teens unleash powerful bombardment of heavy metal music upon all KND operatives, while they are protected with earplugs. At the same time, the bike that both Numbuh 1 and Chad had hijacked crash into the boom box, disrupting the music. Numbuh 362 then calls all of the KND to fight. Immediately, fighting breaks out across the platform.

Meanwhile, Sector V chase down Numbuh Infinity, only to be cornered Numbuh 48 Flavors, who wasn't in league with the KND Splinter Cell as Numbuh 1 suspected, but was refusing Infinity's request to give out ice cream; Numbuh 48 Flavors distastes how every sector steals his ice cream that he spends a lot of time to deliver. He reveals that he planning on blowing up the platform so that no one will steal from him again. Numbuh Infinity regains his composure and states that this situations calls for diplomacy. He then shouts for Sector V to charge. They wrestle with Numbuh 48 Flavors over the detonators but fail to stop him from pressing it, causing an explosion of chocolate ice cream that tears the platform apart.

Up top, Numbuh 1 and Chad are stilling wrestling with each other. Numbuh 1 soon has his opponent caught on a precipice after tying his shoes together. But before he could finish off his former rolemodel, the rest of Sector V turn up in a ship, urging him not to do it. As Numbuh 5 explains, "He's one of us." Turns out, Chad is in fact a Teen Operative and has always been working for the KND; he even claims that he was trying to stop Cree from sending the Moonbase into the Sun. And just today, Chad was going to warn Numbuh Infinity about the teens' trap, but Numbuh 1 blew his cover. Practically every mission Sector V ever went on, Chad was there helping on the sidelines. But "they" still picked Numbuh 1 and not him. Numbuh 1 asks if he's referring to the Splinter Cell. Chad screams to the skies that there is no Splinter Cell; "They" used that to cover their tracks. He goes on to explain that there are KND operatives not even Numbuh 362 knows about. But before he can elaborate further, Numbuh Infinity stops him. Walking down a flight of energy stairs, he reminds Chad that Numbuh 1 will learn what he's been chosen for in due time. But for now, they have to return to base since their positions are compromised. Then they both pick their noses and vanish. Afterwards no one saw Chad or Numbuh Infinity again after that day. Then it is revealed that the two unknown kids talking about Numbuh 1 for the past season is Numbuhs Infinity and 74.239. They say Numbuh 1 is ready to be taken away. However, Numbuh Infinity tells Numbuh 74.239 to stop using the voice synthesizers. Numbuh 74.239 demonstrates how cool it is by saying a deep voice, "Nigel Uno, I am your father!"

The movie opens as Numbuh 1 is narrating, we then see massive factories covering the landscape of Britain and child labor widespread. All of this is controlled by an evil old man later known as Grandfather (though referred to as Pappy by his sons). However, one of his sons escapes a factory with his younger brother chasing him. The older brother climbs up a tree, while the younger brother climbs up to him telling him that he can't just run off in the middle of his shift and that "Pappy" will be angry not finding them.

But the older brother decides just to let him, stating that they've been slaving away making tapioca for 11,000 days straight, and their father does in sneer at them like he's the evil king of the world (which the little brother emphasizes that he is). The big brother states that he's tired of it and just wishes that they could fight back as he kicks the tree, which opens a door and stumbles on to a strange chamber, which contains 2x4 Technology as well as the Book of KND, a legendary book that contains instructions on how to use 2x4 Technology as well as information recorded by previous KND operatives. 
S1 "The Grim Adventures of the KND" 1, 2, 3, 4, 5, 60, 362, T,Grim The Delightful Reaper,Mandy And Billy November 11, 2007 (2007-11-11) S01

In the crossover with The Grim Adventures of Billy & Mandy, when a scythe-related mishap puts Billy stuck in his Dad's lucky pants, only the Kids Next Door can save him from a grounding of a lifetime since he doesn't have a quarter for Ed, Edd, and Eddy to help him unless Mandy carries out her own diabolical plot to take over the organization.When Billy's dad leaves to buy underwear, Billy wears his dad's "lucky pants" despite being told not to. Billy accidentally gets Grim's scythe stuck in the pants, and he tries to get help fixing them before his dad gets home. He calls "Ed, Edd n Eddy's Pesky Problem Fixers", but Billy doesn't have any money, so Eddy tells him to call the Kids Next Door since "they're cheap." The KND soon arrive (Billy is confused by this, stating he tried to call the Power Puff girls"), and they find they need 2x4 Technology, so Numbuh 1 dresses up as Billy to stall Billy's dad, while the rest of Sector V take Billy to the KND Deep Sea Base to fix the pants. Mandy comes to Billy's house, and knows that Numbuh 1 is not Billy. Mandy captures Numbuh 1, and tortures him until Numbuh 1 tells Mandy everything about the KND.

Meanwhile, the rest of Sector V are flying Billy to the Deep Sea Base, and they get an urgent message that the Delightful Children from Down the Lane are using a "delightfulization machine" to make more children into their delightful slaves. Sector V reluctantly takes Billy on the mission, where he mistakes the delightful machine for a bathroom, fusing him, the lucky pants, Grim's scythe and the Delightful Children into a being called the "Delightful Reaper".

Meanwhile, Grim comes to Billy's house, and mistakes Numbuh 1 for Billy. Grim then says that his scythe has been fused with evil and strangely delightful children, and Numbuh 1 realizes that he is talking about the Delightful Children from Down the Lane. The Delightful Reaper begins fusing kids into it, including Numbuh 2.

Sector V returns to the moonbase, where they find Mandy disguised as Numbuh 1. Only Numbuh 5,Numbuh 1,Grim and later, Numbuh 362 knew that she's an imposter, but since nobody else does, Mandy convinces everyone that Number 5 is losing her mind. Soon Mandy becomes ruler of the KND, renaming it the MND (Mandy New Dictator) and told Numbuh 5 that Numbuh 362 lost her mind. Numbuh 1 and Grim arrive at the moonbase, where Grim finds out that Numbuh 1 isn't Billy, and Mandy imprisons them.

The Delightful Reaper continues making children fuse with it, so after escaping, Numbuh 1 and Grim fuse together with the Bone of Barnacles to create a Giant Skeleton Samurai to battle the Delightful Reaper. A giant M.A.N.D.R.O.B.O.T., piloted by Mandy, Numbuh 3 and Numbuh 4 comes into the battle. Mandy's robot begins to lose until Numbuh 1 and Grim show up and fight the Delightful Reaper, though they begin to lose as well because Billy's dad's lucky pants are impervious to lasers, supernatural energy, and mustard.

When the Delightful Reaper is distracted by Numbuh 1 and Grim, Mandy purposely fuses herself with the Delightful Reaper, giving her control of it. However, Billy's dad comes, removes the lucky pants and takes them away, being really, really angry that someone is wearing his pants. Without the lucky pants, the Delightful Reaper is defenseless and the Skeleton Samurai finishes it off, freeing the other kids inside it. Mandy is taken away by the KND, but eventually she escapes, vowing revenge, and everything goes back to the way it was, except for Numbuh 1, mistaken by Numbuh 3 and Billy's dad for Billy, who is dressed like Numbuh 1, which causes the KND to throw various items at him in response to prevent what happened that day.

Note: Ed, Edd n Eddy, Blossom, Bubbles and Buttercup from The Powerpuff Girls, Andy from Squirrel Boy, Adam from My Gym Partner's A Monkey, Dexter, Dee Dee and Mandark from Dexter's Laboratory, Bloo and Mac from Foster's Home For Imaginary Friends, and other Cartoon Network characters make brief cameos at the end of the Cartoon Network crossover episode.

Expanded Acronym: It's Now The Extra Really Very Interesting End Wrap-Up Story
Series Finale. In live-action interviews, Numbuhs 2-5 are re-commissioned as adults and tell what happened to Numbuh 1 on the final mission. In the story, every Kids Next Door operative and villain must go on a scavenger hunt for the Delightful Children's Cake. During the hunt, Sector V is dead last and are losing the Scavenger Hunt. During the interviews, some unexpected things, about Numbuh 2-4, are revealed (e. g. Numbuh 2 has lost most of his intelligence, while Numbuh 4 has gradutated from Harvard University, and that Numbuh 3 is now in charge of Rainbow Monkeys Inc. and has married Number 4. while Numbuh 2 and 5 married each other, although at first it seems like Numbuh 2 and 3 married each but the actual relations are revealed towards the end of the episode). Towards the end it is supposed that when the DCFDTL fell down in the toilet at the park, that most think they fell to their deaths. This means that Sector Z is gone forever too.Though this is highly unlikely as they have been through much,much worse in previous episodes. After getting Father's pipe, Numbuh 1 wins the Hunt and is assigned to help out the Galactic Kids Next Door. After saying goodbye to his parents (who were re-commissioned for this) and his sector, leaving Numbuh 5 in charge, Numbuh 1 leaves Earth for what seems like forever. After the interviews are done, we see Numbuh 5 saying that the re-commissioning is starting to wear off, but she hopes that they helped answer all the interviewer's questions. The man says, "Oh, you've helped me, all right." The camera turns around to show that the interviewer is really Father, who says, "Now I know where Numbuh 1 is!" The transmission is momentarily interrupted, and when it returns, we see Numbuh 5 talking on a 2x4 phone and we hear her say "Yeah,we told him everything he wanted to hear. We'll meet ya back on the moonbase ok? Oh and Numbuh 1, welcome back." which indicates that, at least Numbuhs 2-5 were never de-commissioned, and that the events concerning the GKND were either completely fictional, or Number 1 eventually returned.
