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 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.
When a storm sweeps the Krusty Krab away, the crew and customers must rely on a crazed Krabs to lead them back home; Patrick's last baby tooth needs to come out, but he fears letting it go.
