Head Waiter

Head Waiter is a duel mini-game found in Mario Party 5.

Gameplay
Players take turns tossing a bomb in the likeness of Bowser's head back and forth amongst themselves. The timer on the bomb starts at nine; players may count down either one or two numbers in an effort to avoid being the one to decrease the counter to zero. The player who does so causes the bomb to explode in his/her character's hands, resulting in a loss.

Once the timer reaches below five, the numbers displayed change to question marks, making it impossible to tell whether the player's opponent has docked one or two numbers off the time.

Controls
A button – Lower number by one B button – Lower number by two
