Template:Minigame-infobox Shy Guy Showdown is a Duel mini-game found in the game Mario Party 5.
The object of this mini-game is to be the first to shoot the ink ball at the opponent. A Shy Guy in the middle of the arena raises a sign, and the player must press the button shown on the sign before his or her opponent to win. Sometimes the Shy Guy raises a fake sign (i.e. ! sign or M sign). The player shouldn't do anything in this case or else the ink ball explodes inside the gun, staining the player and making him or her lose. If the player presses the wrong button on a legitimate sign, the same result happens.
The setting in this mini-game is commonly used for simple Duel mini-games. It takes place on a western-themed town. The characters (and the Shy Guy) are standing on an arena, which is surrounded by small houses or buildings.
