Shoot Yer Mouth Off

From the Super Mario Wiki

Shoot Yer Mouth Off is a mic mini game in Mario Party 6. The player with the microphone says a number from one to nine into the microphone to make Shy Guys shoot Bullet Bills or Bob-ombs into a square arena where the other three players must dodge them. If a player is touched by a Bullet Bill or if a Bob-omb explodes on them, they are out of the game. Also, if the player says zero into the mic, a group of three Thwomps will fall in a random location.
