Mr. Chicken is a big bird that may be an apprentice. Mr. Chicken's presence was merely for a gag. He was supposed to make you think he is Chowder until you see the real Chowder, who was right in front of him. Being rejected by Gazpacho, he mumbled in disappointment, "Oh. All right, later." This hints that Gazpacho must help him a lot, perhaps even the same amount as Chowder; yet Gazpacho prefers assisting Chowder even more, despite the fact Mr. Chicken and Chowder had the same problem.
