Why TOAD!? He is just a mushroom with limbs! I think Waluigi should have his own game (Or 1 that has him as either the main villian or 1 of the main villians, DDR: Mario Mix or the Mario sports games don't count, respectively.). There is so much about him that is still a mystery, such as whether or not he is Wario's brother. Stuff like that could be cleared up in a game that were to star him.
