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.

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 turns in a litterbug to the police; SpongeBob and Patrick buy invisible spray from the local prank shop.

Plankton needs help stealing the formula, so he hires an intern who knows more about Mr. Krabs than anyone; Patrick goes into a destructive fit whenever he hears a bell, so his friends help him in their own ways.

The Krusty Krab employees must work around the clock; Mr. Krabs sheds his shell right before the reunion with his old seafaring buddies.
