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.

Squidward closes the gap in SpongeBob's teeth, which causes a dramatic and unexpected change in his demeanor; the newly reformed Clean Bubble takes a dishwashing job at the Krusty Krab, where he is tempted by the grime.

SpongeBob and Patrick take Squidward jellyfishing; SpongeBob is a victim of Plankton's scheme.

When SpongeBob hides the secret Krabby Patty formula in his home, Gary must protect it from Plankton; Sandy must save the day when a freak accident causes everyone in town to become as stupid as Patrick.

SpongeBob uses a "bad" word; SpongeBob enrolls in an art class that Squidward is teaching.
