Cookin is yellowish, spherical being. He has a chef's hat, red, Kirby-like feet and has a wide underbite. In his white glove-like hand, he holds a red frying pan with a silver interior.
Cookins make their first appearance in Rainbow Route. Cookin throws his frying pan like a frisbee as an attack. If the pan hits Kirby, it will catch him and bring him back to Cookin, who will then cook, toss, and flip him. This attack resembles Chef Kawasaki's cooking pan move. Cookins usually stay in their spot, but a Droppy that steals the Cook ability can move.
Whenever Cookin appears, other enemies are generally also around to make sure that the Cook ability can be used effectively. Once Cookin is defeated, he will not appear again until the stage is completed and replayed, as with UFO.
