The Legend of Zelda: Majora's Mask

Skull Kid

While traveling deep inside the Lost Woods, Link is ambushed and knocked off his horse by the Skull Kid, a strange imp wearing a peculiar mask, and his two friends, the fairies Tatl and Tael. The Skull Kid initially seems to recognize Link somehow, but quickly dismisses it, taking his Ocarina of Time. While the Skull Kid attempts to play the ocarina, Link comes to, and approaches the Skull Kid; he tries to lunge at the Skull Kid to reclaim his ocarina, but the imp quickly mounts Epona and takes off deep into the woods. Link is able to hold onto Epona for a little while before being thrown off, attempting to give chase on foot instead. Given no option, Link follows them into an entryway leading into a large, hollow tree. Once inside, Link finds himself on the edge of a great hole, and is too late to save himself from falling into it.

At the bottom of the hole, Link is confronted by the gloating Skull Kid, who claims he "got rid of" Link's horse. Using the evil powers of the mask, the Skull Kid then turns Link into a Deku Scrub. As the Skull Kid makes his exit, Tatl is separated from her brother, Tael, and has no choice but to ask Link's help in reuniting her with her companions. After navigating a complex of subterranean caves, Link meets the mysterious Happy Mask Salesman, who has the power to change him back into his true shape, though he is first required to retrieve his Ocarina of Time in order to do so. In exchange, he asks Link to retrieve Majora's Mask from the Skull Kid.
