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.

Sandy and SpongeBob compete doing underwater sports; SpongeBob and Patrick visit the zoo.

Squidward turns SpongeBob and Patrick against each other; boat-driving exam.

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.

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