Croo is a character from The Legend of Zelda: Skyward Sword. A resident of Skyloft, he is an elderly man that often sits in the Bazaar's cafe, spending his nights at the Lumpy Pumpkin. Croo is extremely proud of his grandson, a Rescue Knight who saves people that fall off of Skyloft. He also replaces Sparrot, the Fortune Teller, when his crystal ball goes missing.
As many residents of Skyloft seem to be named after birds, it is possible that Croo is named after the crow.
