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.
When the key to the vault holding the Krabby Patty recipe is lost, SpongeBob must locate it before the recipe is lost forever.
While working the graveyard shift, Squidward tells SpongeBob a scary story about the Hash Slinging Slasher; Mr. Krabs is smitten with Ms. Puff.
SpongeBob accidentally gives himself a black eye; Plankton brainwashes Mermaid Man and Barnacle Boy to wreak havoc on the Krusty Krab.
SpongeBob and Patrick protest the construction of a highway that would destroy Jellyfish Fields.
