Orin J. Ruffy, also known as The Butler, is a fish who works in a train. In the episode The Great Patty Caper, Ruffy was a suspect in the theft of the key to the Krabby Patty recipe vault. He frequently states that he is not a butler. When the key went missing, he was then searched by a tough cop. Nothing suspicious was found, but it was revealed that he is a criminal who stole $75,000 worth of ham sandwiches. He is voiced by Dee Bradley Baker.
Orin J. Ruffy is a tall fish. He wears a suit resembling a butler's (though he insists that he isn't really one). The suit itself is blue with purple lines going down his pants. He wears a white undershirt with a purple tie. He also wears a blue hat and black shoes. In his true appearance, he has black hair and wrinkles.
Orin J. Ruffy is a pun of Orange Roughy, a type of fish.
His being suspected of stealing the key is based on the gag "the butler did it". However, even though he's not a butler, and he didn't steal the key, he was still a criminal on the run (for stealing $75,000 worth of ham sandwiches).
