Role in episode
SpongeBob dresses up as Fry Boy to stop brainwashed Mermaid Man and Barnacle Boy from going to the Chum Bucket. He is unsuccessful, however, due to their ancient bodies being unable to digest the Krabby Patties he feeds them, and is trampled on by Mermaid Man and Barnacle Boy as he tries to stop them.
