A chadoo is a small, tree-dwelling creature native to the Hork-Bajir homeworld. It has four short, stubby legs and two enlongated arms that end in claws which are connected by skin flaps and is covered in feathers. It's very quick and agile, capable of moving, jumping, and using its skin flaps to glide from tree to tree to eat sap. It probably does not have many inborn instincts, because those who have morphed a chadoo never commented on it.
