Cucco

Cuccos are a species of chickens and a recurring element found in the Legend of Zelda series. They appear as a new item in Super Smash Bros. for Nintendo 3DS / Wii U and as an enemy in the Smash Run game mode exclusive to the Nintendo 3DS version. During a fight, once they are spawned on the stage, they will walk around harmlessly until a player attacks one, a stage hazard disrupts it, or one is thrown at another player, regardless if the player is invincible or shields. Once this happens, a flock of Cuccos flies in and attack the player that triggered the flock, similar to their appearances in The Legend of Zelda. Any other player that comes in contact with the flock will also be damaged. If the Cucco was triggered without player involvement, it randomly targets players. Cuccos that attack from a downward motion have a weak meteor smash effect on players. While the Cucco items take their appearance from The Legend of Zelda: Twilight Princess, the Cucco enemies in Smash Run appear in their original sprite form from The Legend of Zelda: A Link to the Past.

Cuccos are set to reappear as items in Super Smash Bros. Ultimate.
