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 suspects Patrick of stealing his jellyfishing net; SpongeBob builds a ventriloquist dummy modeled after Squidward.

Plankton travels two thousand years into the future and finds a few unfamiliar faces; SpongeBob, Patrick and Sandy find themselves in the middle of a long-standing feud between the Narwhals and the Planktons.

SpongeBob and Squidward take a delivery to a dreaded town where the laws of logic no longer apply; SpongeBob can't stop biting his nails, but he also can't figure out why.

SpongeBob wants to catch an ultra-rare jellyfish and enlists the help of former jellyfishing champion, Kevin; on a trip to the museum, SpongeBob and Patrick teach Sandy all about Bikini Bottom's fascinating, yet questionable, history.
