Guru-Guru

Guru-Guru is a recurring character in the The Legend of Zelda seres. He is often seen playing a phonograph. While he is normally mild-mannered and is a cheerful man, when he becomes agitated, his face warps into a distorted view of his usual expression and the speed of his phonograph increases. He is associated with the "Song of Storms", the song that his instrument plays in all of his appearances.

Guru-Guru is found in the Windmill Hut in Kakariko Village playing the "Song of Storms" on his phonograph. When Link is a child, Guru-Guru is trying to come up with a theme inspiried by the Windmill, but when Link comes to the Windmill Hut as an adult, Guru-Guru is upset because of a child who came to the Windmill Hut and played a song that had messed up the windmill. After taking out the ocarina, Guru-Guru is reminded of the child who messed up the Windmill Hut and teaches Link the "Song of Storms". After successfully learning the song, the Windmill starts rapidly spinning, further upsetting Guru-Guru. If Link plays the "Song of Storms" to Guru-Guru as a child, the Windmill will cause the well to drain.
