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.

Halloween party; Squidward takes care of SpongeBob's pet snail.

SpongeBob must protect the town from a ferocious biker gang; Mr. Krabs and Plankton work together to infiltrate a new smoothie shop.

Plankton wins the cutest baby contest and becomes the face of a baby food brand; when Squidward's one-off portrait of SpongeBob takes the art world by storm, he has no choice but to produce more.

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