Captain Lutefish is a large, lime green fish. He has large, fuzzy hair, almost like an afro, and a frizzy goatee. He also wears a brown jacket and brown pants with no shirt. His black shoes are extremely similar to SpongeBob's.
Captain Lutefish is first seen walking out his office along with Mrs. Puff and SpongeBob, agreeing to sign SpongeBob up for the Derby. Lutefish then announces all of the competors including giving SpongeBob the nickname "The Squish."
Lutefish is then only seen calling the action and never appears again once Mrs. Puff joins the Derby by herself.
