Woodfall is a region of Termina in The Legend of Zelda: Majora's Mask. The region contains the Southern Swamp, the Woods of Mystery, the Deku Palace, and Woodfall. As its name may suggest, the area is abundant in swamplands; however, all the swamp water in the area had been contaminated and rendered poisonous by the Skull Kid before Link arrived. These swamps can usually be crossed by Deku Scrubs by utilizing the Lily Pads found there; indeed, before the swamp water is cleansed after the defeat of Odolwa, it is the only way to safely cross the swamps, apart from by boat.
This region is ruled by a monarchy of Deku Scrubs. Other species have come to live here as well, which is strange due to how territorial the native Deku Scrubs are. The Deku Scrubs rule from the Deku Palace, and refuse to allow anyone except other Deku Scrubs entry. The swamp is also populated by monkeys, but it is unknown where they live.
