An accident-prone yellow sea sponge, who works in a fast-food restaurant, has adventures with his friends in the underwater city of Bikini Bottom.
Mr. Krabs and Plankton have been rivals for longer than anyone can remember - but it wasn't always like that. Mr. Krabs tells the tale of how a great friendship turned sour.
Mr Krabs is determined to uncover Plankton's next devious plot in 'Spy Buddies', we learn advanced boating techniques in 'Boat Smarts', and Mr Krabs holds a competition in 'Good Old Whatshisname'.
SpongeBob moves into the Krusty Krab (so that he'll never be late again) in 'New Digs', and then in 'Krabs A La Mode', Plankton has an idea to cause some chilly trouble for Mr Krabs.
A scary roller coaster opens at Bikini Bottom's amusement park in 'Roller Cowards', then in 'Bucket Sweet Bucket', Plankton tricks SpongeBob, Patrick and Squidward into fixing up the Chum Bucket.
It's a battle of the restaurants in '20,000 Patties Under The Sea', and then in 'The Battle Of Bikini Bottom', Patrick and SpongeBob discover that they have very different views about cleanliness.
SpongeBob accidentally messes up Squidward's face in 'The Two Faces Of Squidward', and then in 'Spongehenge', SpongeBob's sponge brings all the jellyfish to the city.
SpongeBob's singing means no more Krabby Patties in 'Banned In Bikini Bottom'. Then in 'Stanley S. SquarePants', SpongeBob's cousin comes to visit, and quickly turns his life upside down.
SpongeBob gets a bump on the bonce and can't remember who he is. His friends back in Bikini Bottom, who once told him to get lost, soon find they're missing him.
