He is an elderly fish that is yellowish tan with yellow stripes on the side of his head and has a light green dorsal fin. He wears a light gray shirt and black pants.
He is a part of a running gag which involves Plankton getting run over by the elderly fish and his car. Plankton drives up to the drive thru and is about to order a Krabby Patty, when the Elderly Fish drives up, and, not seeing Plankton, drives right over him. The Fish keeps then drives away because no one is there to take his order. The Elderly Fish returns later in the episode and runs over Plankton again.
