Duck Hunt (also known as the Duck Hunt Duo) is a playable character in the Super Smash Bros. series. They are from the video game of the same name, Duck Hunt.
Duck Hunt made their first appearance of the game of the same name. In the video game, the player using the NES Zapper must shoot down the ducks that fly around on the screen. If the player successfully shoots a duck or ducks, the Dog will pick up the duck(s) and a cheerful jingle will play. However, if the player misses all of the ducks on the screen, the Dog will point and laugh at the player at their failure. This will continue until the player runs out of lives.
The duo made a cameo in the microgame in WarioWare: D.I.Y..
