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.

Mr. Krabs has an accident and leaves SpongeBob in charge of the Krusty Krab; Patrick takes a job at the Goofy Goober when he finds out the employees get free ice cream.

Squidward's new life is threatened; stuck in her dome, Sandy suspects Plankton's up to no good and gets Patrick to investigate.

SpongeBob and Patrick create their own zoo that is made entirely of bubbles; the Krusty Krab goes under emergency quarantine, but no one knows who is carrying the mysterious illness.

SpongeBob's new friend is a giant, fluffy hamster that no one else can see; Patrick wants to be a horse.
