That's So Raven (season 2)

On Halloween, Victor accidentally switches Raven and Chelsea's burgers at the Chill Grill, Chelsea wears a badge that has a cow on it after being ashamed that she enjoyed the bite of Raven's hamburger that she ate. They then conjure up a wishing spell from Viv's book and use it to go to Alana's, Raven's arch-nemesis, Halloween party that they weren't invited to. However, Chelsea's badge falls into the cauldron they were using, and this causes Raven and Chelsea to both slowly turn into cows. They go to the party in an attempt to stop the spell as their body and behavior continue to change into that of two cows. Meanwhile, Cory chooses to go trick-or-treating with his friend rather than his parents, upsetting Victor and giving Tanya the idea that the two of them should go trick-or-treating without their children.

Raven sees a vision of a TV cart running into Alana in the school hallway, so when the TV cart comes, Raven pushes Alana out of the way and accidentally into blue paint. When Alana goes to the hair salon, Raven goes there to apologize, but Raven overhears Alana saying she will get revenge on her. Raven pretends to be a hairdresser, and when she's fixing one of Alana's hairs, her gum gets stuck to it. Loca and Muffy point out that Raven has damaged Alana's hair, and Raven runs out of the hair salon silently. Raven tells Chelsea about fixing Alana's hair. That night, Cory and his friend William (who have chicken pox) agree to help Raven the next day with technology, which helps her avoid Alana at school.

Note: Even though Devon and Alana were formally introduced in this episode, Devon and Alana appeared in "Out of Control" and "Don't Have a Cow" respectively. This is due to the episodes airing in a mixed production order. Also when Cory and his friend itch each other backs, it was shown in Hannah Montana with Miley and Lilly.

When Principal Lawler introduces a new school uniform, Raven decides to protest, and ends up being the only one. But was supported by Alana and her posse. When she has a vision of the group seeking revenge, Raven attempts to stop their scheme, which involves a large wheel of smelly cheese being put into a hot air vent, and framing Eddie and Chelsea. To prevent them from getting in trouble, Raven enters the air vents only to find herself stuck, realizing the only way left to get rid of it is to eat it. Meanwhile, Cory's pet gets a credit card in the mail, which Cory and William use to buy expensive stuff, until Victor tells them that someone will eventually have to pay for it.

When Eddie hosts a radio show at school, with Raven as a guest/co-host, Raven and Eddie clash over hosting duties. Things go terribly wrong when Raven makes Eddie mad, and he quits. Raven embarrasses herself on the radio show, and does not know how to operate the machines. In the end, Eddie forgives Raven, and she gives Eddie back his hosting duties.

Cory has to go to the dentist. He is terrified, so Raven goes with him to calm his fears. When they get there, Raven sits in the dentist's chair to show Cory that there is nothing to be scared of - until the dentist (Tom Virtue) tells her that she has a cavity. Suddenly scared, the two of them try to run, ending up with Raven posing as "Dr. Thinkenfast" ("Thinking fast"), and Cory as "Dr. Doasisay" ("Do as I say"). Meanwhile, Victor; Chelsea; and Eddie are working on a Chill Grill advertisement video, but struggle over creative control.

Raven and Chelsea get waitress jobs at The Chill Grill to raise money to go on a ski trip. They chat with customers, and ignore their duties, so Victor fires them. They persuade him to give them another chance, and try to plan a big party for the restaurant that night. Unfortunately, they both plan a separate party, along with one already booked, leading to three bashes on the same night.

Raven tries to make peace with Alana to avoid suspension from school, by inviting her to what turns out to be her first sleepover. However, things get ugly when Raven has a vision that there'll be an earthquake. Meanwhile, Eddie turns to Victor for driving lessons, though they are not quite what he expects.
