Duck Jump (named Duck Jump Duo in the PAL release) is Duck Hunt's up special move in Super Smash Bros. for Nintendo 3DS / Wii U. The duck starts to fly up into the air, carrying the dog with it. Players can control their horizontal movement while the duck flies.
This move also has two custom variants. The first is Duck Jump Snag, which involves the dog also biting to attack nearby fighters, but the duck cannot fly as high. The second is Super Duck Jump, which pushes the duo high into the air, creating a whirlwind that pushes away opponents, but the player cannot move as far horizontally.
