Coo is a large owl-like creature and one of Kirby's six Animal Friends, making his first appearance in Kirby's Dream Land 2. He is distinguished by his frilly purple and white plumage, his piercing eyes, and his sharp talons, which he uses to keep a grip on Kirby as they travel together. Pairing up Coo with Kirby allows for a number of different methods of attack based on what Copy Ability the pink puffball has, though these vary heavily in effectiveness. Coo makes his most prominent appearances in Kirby's Dream Land 2, Kirby's Dream Land 3, and Kirby Star Allies, where he is a playable character (though always paired up with either Kirby, Gooey, or another Animal Friend). He has appeared in a large number of other games as well, though he rarely makes more than a cameo appearance, and is seldom seen in isolation from Rick and Kine. Coo also has a supporting role in the anime series Kirby: Right Back at Ya!, where he has the ability to speak in full sentences and is seen as the wisest of Dream Land's intelligent animals.
