Duck Hunt (WarioWare: D.I.Y. Showcase)
From the Super Mario Wiki
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 and there is one duck on Level 1 and two on levels 2 and 3.
