Pierre

From Zelda Wiki.org

Pierre is a scarecrow appearing in various places of Ocarina of Time, if the Scarecrow's Song has been taught to Bonooru first. He can then be used as a Hookshot target to allow Link to reach previously unreachable areas.

Another scarecrow by the name of Pierre appears in Majora's Mask, only this time the song is taught to him and played only for him. He serves much the same function as Ocarina of Time's Pierre, and also acts as the teacher of the Inverted Song of Time and the Song of Double Time.

Trivia

• If you complete Ocarina of Time and wait for the ending credits to finish you will hear the Scarecrow's Song that you composed.
