Woodfall

In Majora's Mask, Woodfall is the area within the water-filled crater of an extinct volcano, and is home to the submerged Woodfall Temple, which Deku Link can enter by playing the Sonata of Awakening on the Deku Shrine platform. It also contains numerous enemies, several treasure chests (of which one holds a Piece of Heart), and a Great Fairy Fountain which grants Link the improved Spin Attack.

When Link first enters Woodfall, it is completely covered with poisonous water. The only way to get around the swamp is to stay on the planks, although they are being protected by Hiploops that could potentially knock Link down into the water. Moreover, to get from plank to plank, the Mad Scrubs at the end of the platform must be defeated in order for Link to be able to use the Deku Flower, allowing him access to the next set of planks to finally reach the Deku Shrine.

Once at the Deku Shrine, Tatl makes a note of the Deku Scrub mark inscribed upon it and wonders whether they used that area to worship.

After Odolwa has been defeated, the waters of Woodfall and the rest of Southern Swamp are cleansed, allowing access to a hidden chamber within Woodfall that houses the imprisoned Deku Princess.
