He has the same appearance as SpongeBob, except he wears round pants that have the same design as his regular pants.
Role in episode
SpongeBob behaves like he is a new employee at the Krusty Krab and asks for Squidward's help. Following Squidward, he starts copying the latter's actions, such as being rude to customers, throwing the trash out to the dumpster, sleeping in the bathroom or at the workstation, and even cooking Krabby Patties like Squidward (burning them). He is gullible, much like his original identity's character.
