Guru-Guru

Ocarina of Time
Guru Guru is the hyper, and easily angered Windmill man of Ocarina of Time. He stands in the windmill playing his phonograph, trying to make the windmill rotate at the right speed. A look of concentration can be seen on his face. He hates it when Link plays the Song of Storms on his Ocarina and when he plays it as an adult he gets even more annoyed. He is slightly similar to the Happy Mask Salesman, as both are constantly smiling and have brief moments of surreal rage. During the credits, he is seen being held upside-down by a few kokiri.

Majora's Mask
In Majora's Mask, Guru Guru can be seen in the Laundry Pool area of Clock Town playing his phonograph again. He is a very happy person but is full of guilt as he stole a mask by the name of the Bremen Mask from a dog, who could get any animal to follow his command. He gives you this mask as a reward for listening to his story and to get rid of his guilt. His theme song is the Song of Storms. If you listen carefully to his words, they match up with the notes he plays. He also appears in the Stock Pot Inn in the room at the end of the hall. This room is occupied by the Gorman Troupe. In the daytime, it is occupied by Guru-Guru and Marilla Rose of the Rosa Sisters.

Oracle of Seasons
He also appears in Oracle of Seasons where he stands by his windmill playing his theme song, although sounding a little different from the two games before. His only use is later in the trading sequence when you give him engine grease and he gives you his phonograph which is used to play for the Deku Scrub in the Tarm Ruins. This is not necessary, if the player remembers how to get the Noble Sword.
