Shy Guy is a badass dude who wears a mask because his face's too awesome to be seen in public. The only people who have seen his face and lived are Luigi and Elmo (who later died). Shy Guy's favorite sport is Tennis because he's good at it and his least favorite sport is baseball because he's too slow! He also seems to dislike Yoshi for some reason.
