The Popeye Fish is a tough fish that has made minor appearances in the show.
He is a large, muscular, light grayish brown fish that 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.
His largest appearance is in the episode "No Weenies Allowed," where he is seen trying to enter The Salty Spitoon. His other large appearance is in "The Cent of Money," where Mr. Krabs and Gary steal his change. When SpongeBob comes looking for them, he tells SpongeBob that they had stolen his change, and referred to them as "Criminals." A brief appearance of him is shown in "Plankton's Army " when Plankton asks him and a group of other fish to be his henchmen to steal the Secret Formula. He and the other group of fish end up stepping on Plankton causing him to return to the Chum Bucket in a wheel chair with a cast and bandages.
