The Legend of Zelda: Majora's Mask

Majora's Mask opens with Link leaving Hyrule on personal business. His trip is interrupted by the Skull Kid and his two fairy buddies, Tael (the purple one) and Tatl (the white one). Skull Kid, with his fairies' help, knocks Link off Epona and steals the Ocarina of Time. When Link awakes, the Skull Kid takes off and leads Link on wild chase.

The Legend of Zelda: Majora's mask is the sequel to the popular action role-playing game The Legend of Zelda: Ocarina of Time. You do not need to have played any previous Zelda games to enjoy Majora's Mask, but it helps! Many of the conventions pioneered in Ocarina of Time are present in Majora's Mask and you'll have an easier time getting into the flow of the game if you are familiar with the game engine, weapons, and other items unique to the Zelda universe.

The premise of Majora's Mask is simple; Link has to save the world in three days. With the Ocarina of Time, the insturment given to him by Princess Zelda of Hyrule in his last  adventure, Link can relive those three days as many times as needed to perform the tasks required to save Termina from destruction.

Of course, Link is the only character in the game effected by the Ocarina's time-traveling abilitys. All of Termina's other inhabitants go about their daily routines as if nothing has happened. When Link resets time, all of his interactions with the people of Termina are erased from their minds. Conversations never happened, rescues never occurred, and, on the plus side, treasure chests were never opened. Very few things excape the vortex of backwards time travel except the things that Link needs to complete his quest: such as weapons, equipment, and masks.
