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.

SpongeBob discovers that Squidward has never actually tried a Krabby patty; a bully threatens SpongeBob.
Plankton creates a clone of himself and Mr. Krabs, but neither restaurant is safe from the newcomer; Squidward gleefully switches jobs with a bus driver for an easy ride, until SpongeBob and Patrick climb aboard.
