Duck Hunt (WarioWare: D.I.Y. Showcase)
From the Super Mario Wiki, the Mario encyclopedia
Just like the real game, the objective is to shoot the ducks, but only three are needed. The player must point the at a duck and press to shoot. If the player does not shoot all the ducks, they will lose. In WarioWare Gold, the game is normal-length.
