Mr. Sea Chicken is a sea chicken that only appears in the episode "The Masterpiece." He is the owner and mascot of the Sea Chicken Shack, a restaurant in Bikini Bottom. Although they have never physically met, he and Mr. Krabs are enemies, due to the competition between the Sea Chicken Shack and the Krusty Krab, who both claim they have the "best restaurant in the sea."
Mr. Sea Chicken is an anthropomorphic white, feathery chicken who walks on two legs and has a small, orange beak. He occasionally sheds feathers, especially when moving around. He does not really wear any clothes, but because he has feathers, he does not need any. Mr. Sea Chicken has a screechy voice, and when he talks he sometimes clucks.
Advertising and marketing
Sea Chicken Shack Commercial
In order to bring customers, Mr. Sea Chicken made a commercial for his Sea Chicken Shack. The commercial used him as the star, telling kids to bring their families to the restaurant. He also showed kids playing on him, a reference to the large statue of him (Picture in infobox for reference).
Right next to the Shack is a huge, realistic, unsafe statue of Mr. Sea Chicken for kids (and SpongeBob) to play on. It looks like it is made of concrete. The statue shows a lot of detail, as individual feathers, eyes, and a beak are easily seen on it.
Mr. Sea Chicken lives underwater without an air helmet to breathe. This is probably because he is a Sea Chicken (which is fictional and not an actual chicken species in the real world).
In the commercial, he lets kids play on him while he strikes a pose. This is a reference to his statue on the restaurant.
