The Spring Water Cave is a location from The Legend of Zelda: Majora's Mask. It is a cave situated at the top of Ikana Canyon in Ikana. When Link first enters the cave, he finds that it is dried up, and that the evil Composer Brother, Sharp, is residing inside. Sharp plays a strange song which he calls the "Melody of Darkness". It creates a purple miasma which slowly drains Link's health, and Link must seek out Sharp's brother Flat, if he hopes to defeat Sharp.
On the night of the First Day, Link ventures to Ikana Graveyard and dons the Captain's Hat. By doing so, he is able talk to the Stalchildren that patrol the graves. The Stalchildren open one of the graves, and Link proceeds below the earth, into a cavern-like area. After braving many dangers, including a battle against an Iron Knuckle, Link meets Flat, who teaches him the "Song of Storms." If Link plays the "Song of Storms" for Sharp in Springwater Cave, he comes to his senses and apologizes to Link. As a result, the river, whose source is in Spring Water Cave, begins flowing again, thus fixing the waterwheel on the Music Box House and scaring away all the Gibdos in the area.
