The Legend of Zelda: Majora's Mask

Final Battle

Gradually, Link learns from the Four Giants that the Skull Kid was once their friend, whom they had to leave behind when they left Termina to guard the land from their sleep. Using the "Oath to Order", Link summons the Four Giants on the eve of the Carnival of Time; they are indeed able to stop the Moon from falling, and the Skull Kid is rendered unconscious. As a reunited Tatl and Tael celebrate their victory, however, the mask reveals itself to be capable of acting on its own power; it travels into the Moon and is able to bring it down with more force, preventing even the Four Giants from stopping it from consuming everything. Though Tatl initally pleads with Link to restore time to the First Day, he realizes that they must destroy the spirit within the mask to free the land. Link bravely ventures after the mask.

Inside, or on, the Moon, Link finds himself on a pastoral, green field populated by strange children wearing the Boss Remains, as well as one wearing Majora's Mask. If Link trades all of the masks he has accumulated and solves the trials set forth by the children, the one wearing Majora's Mask will challenge him to a fight; to make the battle more fair, he presents him with the Fierce Deity's Mask. After Link defeats the three forms of Majora, the mask is rendered powerless, and a new day dawns. The Four Giants, though they must depart once more, make friends with the Skull Kid, and the Happy Mask Salesman has his mask. Though hesitant, Link leaves Termina behind to continue the search for his missing friend, as the happy inhabitants of Termina celebrate the Carnival of Time.
