Link from the X-Cult hack forum, has found some unused characters in the code of Mario & Sonic at the Olympic Games for the Wii: Birdo, Donkey Kong, Jet & Silver. Other “hidden” characters like Shy Guy, Goomba or the Monkey, are normally used only in the background of the game, but thanks to the WiiRD they became playable and some of them have even animations for the various olympic games.
