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.
Plankton creates a clone of himself and Mr. Krabs, but neither restaurant is safe from the newcomer; Squidward gleefully switches jobs with a bus driver for an easy ride, until SpongeBob and Patrick climb aboard.
Patrick befriends a sea monster; SpongeBob and Squidward search for answers when things begin to disappear from Bikini Bottom; Madame Hagfish puts a hex on the Krusty Krab; SpongeBob and Patrick search for a legendary drain on the ocean floor.
Not knowing the contents of Pat's secret box drives SpongeBob crazy; Squidward lies to an old rival about having a band.
Plankton and Karen take dance lessons; equipped with a magical spell book, SpongeBob cooks up chaos in the Krusty Krab kitchen.
