Dream Boxing is a dream event in Mario & Sonic at the Olympic Games and exclusive to the DS version. This event pits two characters in a 4-competitor tournament. Opponents attack each other with a series of punches to reduce the other stamina resulting in a knock-out. If the opponent does not stand up before the referee counts to ten, the victor wins by a K.O. (Knock out). Special Punches make the opponent lose a lot of stamina and in some cases, a K.O. Sometimes, the player can block the Special Punch and lose little stamina.
