He is a green fish with blue fins and a red and white sports suit, red shorts, and red and white shoes. He has a red headband, has a jersey on with the number 7, and has red pants. He is a frequent runner and was preparing to be in the Bikini Bottom Marathon.
He first appeared in the episode when he was in his room in the Bikini Bottom Hospital, saying he broke his legs and asking is he could run in the marathon next week. SpongeBob fixed his legs by stuffing a fish skeleton into his body. However, he broke his legs again when SpongeBob ran him over with Mrs. Puff's out of control iron lung.
