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.

While working the graveyard shift, Squidward tells SpongeBob a scary story about the Hash Slinging Slasher; Mr. Krabs is smitten with Ms. Puff.

The long-lost episode of "Mermaid Man" is finally showing on TV, but SpongeBob may not make it home in time to watch; Karen gets a computer virus, and it's up to SpongeBob to get it out of her.

Patrick discovers that the rock he lives under is actually a sea turtle that overslept; old Man Jenkins disrupts business as usual at the Krusty Krab, but Mr. Krabs can't find a way to kick him out.

SpongeBob thinks Mr. Krabs is a robot; SpongeBob and Patrick care for an abandoned baby clam.
