Ballad of the Wind Fish (Majora's Mask)

The "Ballad of the Wind Fish" is a song from The Legend of Zelda: Majora's Mask. Unlike most other songs in the game, this song's information is not stored on the Quest Status Subscreen, and cannot be played regularly. It plays a part in one of the game's sidequests.

Story
During the opening hours of the Milk Bar on the First and Second Days, Toto, manager of The Indigo-Gos is testing the performance stage. Upon seeing Link, he asks him if he wants to help him out and play the instrumental parts of the song. Link uses his transformation masks to play the different instrumental tracks of the song with their different instruments. Link plays it in his Deku, Goron, and Zora masks as well as his normal Hylian form. When the different tracks are being performed, Gorman, leader of the Gorman Troupe complains about how bad it sounds. After the performance is successful, however, Gorman is moved by the song, which he had heard once in his childhood and inspired him to join show business. As thanks, he gives Link his Circus Leader's Mask, a mask bearing his likeness.

Super Smash Bros. Brawl
The song was supposed to appear in Super Smash Bros. Brawl, but was taken out of the final version of the game for unknown reasons.
