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.

After arriving one minute late for work, SpongeBob decides to move into the Krusty Krab so that he will never be late again; when Plankton secretly turns down the thermostat at the Krusty Krab the entire restaurant freezes over.

SpongeBob, Patrick and Squidward buy Mr. Krabs a new mattress; Plankton sues Mr. Krabs after falling at the Krusty Krab.

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 tries to convince a bouncer that he is tough enough for the Salty Spitoon; Squidward's archenemy returns.
