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.

Squidward's prankster dad visits and brings all sorts of gags with him, much to Squidward's annoyance; Plankton tries to get a taste of the secret formula by attaching himself to SpongeBob's tongue.

Patrick gets his license and wins a car; a document reveals that Patrick is next in line to become a king.

When the Krusty Krab runs out of mustard, Mr. Krabs sends SpongeBob, Patrick and Squidward to dig up some more; SpongeBob and Sandy have to collect Krabby Patty ingredients, but Plankton follows their every step.

Patrick's big sister Samantha comes for a visit.
