The Unnamed Sailor is a fish who only appears in the episode "Sandy, SpongeBob, and the Worm." He makes only a minor appearance in the episode.
He is a light brown fish who wears a yellow raincoat. He also has a hook on one hand, meaning that he at one point lost the hand.
He appears when the citizens of Bikini Bottom are debating what to do about the town being destroyed by the Alaskan Bull Worm. The sailor appears when he makes a loud screeching noise with his hool, but only asks for where the bathroom in the Krusty Krab is.
