Majora's Mask

Majora's Mask: This is the evil mask that causes all the trouble around Termina. When the impish thing called Skull Kid (from Ocarina of Time) steals the Mask of Majora, he becomes an evil person. The mask has powers beyond belief. It is making the moon fall. After freeing all the giants, the mask comes to life and you must fight it. Beating it will result in you beating Legend of Zelda: Majora's Mask.
