Should be easy, I mean do you have the Wii game?
If you do, take some screenshots. I have the game, but I don't have a video capture card..
Take some to use as the wing animations, and 9 to use as directions, then take the directions and distort the wing animation to match the direction. Thats the easiest way I would think- Or simply rip the sprites with a Wii modchip..
