How found: Take a right turn at the entrance of the Deku Palace and hop across the lilipads to a Magic Bean spot. Plant and water a bean there and ride it up to the upper level of the fortress. Cross the long sequence of Deku Flowers and you'll eventually reach the cage with the captured monkey. After failing to cut his ropes and learn the song as normal Link, he'll teach you the song as Deku Link.

    How used: Play the song to awaken sleeping objects or characters and open Woodfall Temple.
