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, Patrick and Squidward are locked in a time capsule; SpongeBob and Patrick build a dream world for Squidward.
Squidward finds SpongeBob's diary, and starts reading it out loud in the Krusty Krab; SpongeBob fails his driving test, forcing Mrs Puff to think outside the box and off the road.
Mr. Krabs convinces SpongeBob and Patrick to join him on a treasure hunt; SpongeBob gets on the wrong bus.
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.
