SpongeBob SquarePants (season 1)

It's mass chaos at the Krusty Krab when Plankton, Mr. Krabs' physically tiny business rival (and a determined, unsuccessful one at that), tries to steal the Krabby Patty formula for his own restaurant, the Chum Bucket. But as usual, Mr. Krabs stops him. That night, Plankton tries to con SpongeBob into giving him the formula. Spongebob refuses. Plankton has to go to his last resort - controlling SpongeBob's mind. Plankton gets just inches away from getting the secret formula by trying to make him drop a Krabby Patty into a machine that traps any item put into it and tells him the exact ingredients. But SpongeBob, when he is about to drop the Krabby Patty into the machine, begins to cry, describe how delicious the burger is, and reveals the ingredients using his own words, Plankton becomes extremely tempted to eat the Krabby Patty. But Plankton ends up accidentally trapping himself into in his own machine before he can succeed in eating the Krabby Patty. SpongeBob then leaves the Chum Bucket, and Plankton yells in horror.

• First appearance: Sheldon J. Plankton, Karen the Computer Wife
• In this episode, Plankton is smaller than in the rest. 

SpongeBob has to go to boating school as he continues to fail his driving test. He shares this info with Patrick, and Patrick decides to secretly give SpongeBob instructions during the test via walkie-talkie. He wears a ten-gallon hat on his head to hide the walkie-talkie antenna protruding from his head (as Patrick shoved the walkie-talkie into there). SpongeBob almost passes, but, feeling guilty, ends up revealing that he is cheating. He distracts himself while he says this, and causes him to accidentally run the boat off the road, thus failing the test.

• First appearance: Mrs. Poppy Puff 

A customer asks for a pizza from the Krusty Krab, so Mr. Krabs takes a Krabby Patty turning it into a pizza. SpongeBob and Squidward then are sent to deliver it. Squidward tells SpongeBob to back up the delivery boat, but instead, he panics (as he never passed his driving test), and throws the boat into reverse, speeding backwards into the distance. Unfortunately, the boat runs out of gas and the two cannot find their way back to Bikini Bottom while on foot. The two go on a very tiresome journey, but after using SpongeBob's pioneering skills (where Squidward uses a reference to the television series, The Beverly Hillbillies calling SpongeBob; Jethro every time he refers to the pioneers), including nutty hitchhiking, moss to civilazation, and riding a rock, they finally reach the customer's house. But the customer is not pleased at all that he did not get the soda he insists he ordered with his pizza (to which he did order the soda, but at the time Mr. Krabs placed the phone down). He gets really unnecessarily mad with SpongeBob and he refuses to pay for the pizza, making the sponge cry. Feeling sorry for a heartbroken SpongeBob, Squidward slams the pizza in the customer's face and they both return to the Krusty Krab after the "successful" delivery. But, Squidward soon discovers that there was a shortcut from the Krusty Krab to the customer's house, and that the two had taken a different route (and an unnecessarily long one).

• This episode was voted to be the #1 SpongeBob episode of all time by fans in The Ultimate SpongeBob Sponge Bash. 

A horde of hungry Nematodes come to town and, after eating several indigestible objects, become thirsty and "drink" Spongebob's house. When this happens, SpongeBob plans to move back with his parents, though with a lot of reluctance because he'll miss his old house and friends dearly. Squidward is, unsurprisingly, excited about the idea of SpongeBob leaving, and even parties, but Patrick does everything he can to keep him from leaving whether it be building a new house or offering him to be a "rock mate". This proves to be short-lived, due to Patrick's loud snoring at night and dreaming about a fear of spiders (while sleepwaking, he beats Spongebob with his rock). The next day, SpongeBob's parents arrive to take him to their home. Squidward dances with joy on the spot where SpongeBob's house used to be. As a last memento, SpongeBob puts what he thinks is a pebble in the ground where the house used to be. SpongeBob cries and a tear drops from his nose completely drenching the seed. The seed grows into a new house for SpongeBob. The ground starts to shake, and his house grows back, with Squidward being stuck underneath of it. SpongeBob decides to live in his pineapple house again now that it's restored.

• First appearance: Harold SquarePants, Claire SquarePants 

SpongeBob and Patrick discover that their favorite actors/superheroes, Mermaid Man and Barnacle Boy, live in Shady Shoals, a retirement home on the other side of Bikini Bottom. They try to convince the crime-fighting duo to come out of retirement through several different tactics. As a last resort, SpongeBob pretends to be robbed by Patrick, and then paint their Invisible Boatmobile (which was literally invisible until it was painted). Enraged by the constant annoyance that the sponge-starfish duo create, the duo attack SpongeBob and Patrick with several superpowers, with the final one being the summoning of all the elderly people residing in the retirement home (who were once the "creatures of the deep" who assisted Mermaid Man and Barnacle Boy on a regular basis). They form an angry mob, pick up SpongeBob and Patrick, making the sponge and starfish wrongly assume that the mob considers them heroes, and throw them away. Ultimately, Mermaid Man and Barnacle Boy decide to come out of retirement, though they decide to still reside in the retirement home.

Bubble Bass, a picky overweight fish, comes to the Krusty Krab for a Krabby Patty. Bubble Bass says SpongeBob forgot the pickles, and SpongeBob, shocked by this, loses his confidence to the point where he becomes unable to perform even simple tasks anymore, and he takes a leave of absence, with Squidward as the substitute fry cook. However, Squidward proves to be a terrible chef, burning everything he touches, including milkshakes. Mr. Krabs goes to SpongeBob's house and gives him the ingredients to a Krabby Patty. After three days of frustration, he successfully makes a Krabby Patty. SpongeBob returns to the Krusty Krab when Bubble Bass orders another Patty and he claims that there are still no pickles. But SpongeBob discovers that Bubble Bass hid the pickles (all of the ones from both of the Krabby Patties that SpongeBob served him in this episode) under his tongue, apparently just to humiliate SpongeBob.

He tries to aid others, but only ends up causing terror and chaos in town. A paperboy randomly gives newspapers that state a maniac is destroying the town, and, after a failed attempt to catch the maniac and causing more chaos, SpongeBob discovers that he is the maniac that was mentioned in that newspaper story.

But thinking that they're on the moon, SpongeBob forgets about Sandy and says that she's going to hate them for stealing her rocket, they capture many of Bikini Bottom's inhabitants, thinking it will impress Sandy, because they wrongly assume that they are "aliens" disguised as the Bikini Bottomites, and that they can't trust them. After capturing a lot of them, SpongeBob and Patrick begin to believe each other to be "aliens", and Patrick, during an attempt to capture SpongeBob (who was about to capture Patrick), accidentally captures himself with a net, and SpongeBob puts him in the rocket. SpongeBob believes himself to be finished with his mission to capture as many "aliens" as possible, as there isn't any more room in the rocket to contain any more. SpongeBob travels into space (taking all of his hostages with him) and lands on the Moon, thinking he has returned to Bikini Bottom.

It is the real Squidward, who is wearing a turban and bathrobe and is in fact alive, but SpongeBob and Patrick think that it is his ghost. Squidward is angry at them for destroying his replica (by exclaiming "Look what you've done to me!") and the two are convinced that he really is dead, believing he will angrily haunt them.

SpongeBob tells Squidward it is "'Employee of the Month' Day", however Squidward tells SpongeBob that the award is a scam to make him work harder for no money (this is true), but SpongeBob denies this and says that Mr Krabs gives it to him because he works harder. Mr. Krabs tells SpongeBob (who had won the Employee of the Month award 26 months in a row) that Squidward may win the award. SpongeBob tries to work harder so he could win, but instead flings the patties in the fan, spraying meat at Squidward (Probably because his worrying of not becoming Employee of the month). Squidward tells SpongeBob that the award is a joke, and when SpongeBob boasts that he is better than Squidward, the latter angrily vows that he will be the new Employee of the Month. They both decide to wake up earlier than each other. SpongeBob tries to destroy Squidward's alarm clock so he won't wake up, but Squidward has 58 more in his closet. They set up traps on each other the next day, but give in and run to The Krusty Krab. They overwork excessively and make so many Krabby Patties that they fill and destroy the Krusty Krab. Numerous customers think that they are free, after the explosion but SpongeBob and Squidward are more concerned with who won the Employee of the Month award than stopping them.

"Scaredy Pants" is a Halloween special. SpongeBob is always scared on Halloween, and everyone takes advantage of this, calling him "Scaredy Pants". SpongeBob has had enough of the teasing, so with Patrick's help, he decides to dress like the Flying Dutchman (really a plain bedsheet). SpongeBob is square, so nobody is scared and are instead laughing. Patrick shaves down SpongeBob's body so that he has a rounded top. When SpongeBob gets to the Krusty Krab's Halloween party, he successfully scares everybody until Patrick is stung by a jellyfish, and runs around in pain, throwing SpongeBob around on the rope and revealing his identity. The real Flying Dutchman, offended by SpongeBob's portrayal of him, arrives to steal everyone's souls, but SpongeBob scares him and everyone else away by taking off his costume, showing his exposed brain.
