A square yellow sponge named SpongeBob SquarePants lives in a pineapple with his pet snail, Gary, in the city of Bikini Bottom on the floor of the Pacific Ocean. He works as a fry cook at the Krusty Krab. During his time off, SpongeBob has a knack for attracting trouble with his starfish best friend, Patrick. Arrogant octopus Squidward Tentacles, SpongeBob's neighbor, dislikes SpongeBob because of his childlike behavior.

The friends become unstoppable after Sandy teaches them karate; before long, the entire town learns the martial art and joins the action.

Patrick becomes a superhero and plans to clean up Bikini Bottom; SpongeBob must take drastic measures when Gary becomes obsessed with his new red ball.

When Squidward sets out to prove that anyone can write a comic book, his work garners an obsessed fan base; an actor shadows SpongeBob in preparation for his next big movie, but his dedication to the role becomes a headache for SpongeBob.

SpongeBob visits the dreams of others; SpongeBob comes down with the sniffles.
