He has the same design as SpongeBob, but wears long pants that have the same design as his regular pants.
SpongeBob still works at the Krusty Krab until he realizes how messy the customers eat their food. So SpongeBob quits his job. Later, he hangs with fancy fish and they have a formal party and watch The Table. He then says he wants to see The Mermaid Man and Barnacle Boy Movie and admits he works at the Krusty Krab, causing the fancy fish to leave SpongeBob.
After not being allowed to enter the movie due to having long pants, SpongeBob starts crying. Mr. Krabs appears and removes the pants using his claws.
