The Popeye fish is a tough fish who makes several cameo appearances throughout the series, starting with the episode "No Weenies Allowed."
He is a large, muscular, light grayish brown fish who wears navy blue underpants and a gray sailor's hat. He has yellow eyes, a scar above his left eye, and stubble on his chin. He has very short legs in contrast to the rest of his body.
Plankton asks him and a group of other fish to be his henchmen to steal the Krabby Patty secret formula. He and the other group of fish end up stepping on Plankton, causing him to return to the Chum Bucket in a wheelchair with a cast and bandages.
