Waddlewings are enemies that debut in the Wii U game New Super Mario Bros. U. They are orange flying squirrel-like creatures with brown hands and feet, beady eyes, a red nose and a mouth with two teeth coming out. They also have orange membranes attached to their hands and feet and a cream-colored hindhead, ears and belly.
Waddlewings are rather common enemies, mainly found in Acorn Plains and sky levels. Most of the time, Waddlewings glide from side to side. When they land, they will walk slowly and try to walk off a ledge to glide in that direction. If they bump into a wall while gliding, they will cling to it for a second and then glide the opposite direction. Waddlewings can also carry Super Acorns and drop them if they are defeated. They behave like the Super Koopas from Super Mario World, but instead of obtaining equilibrium in flight, they will always glide diagonally.
