Stray Fairy

The Stray Fairy is a symbolic representation of a portion of a shattered Great Fairy, with appearances in Majora's Mask and Oracle of Ages. In a region where a Great Fairy lay at the mercy of her Stray Fairies, they will appear individually and often at hard-to-reach heights or inside treasure chests; the collection of all the Stray Fairies in a region will facilitate the resurrection of said Great Fairy, upon returning them to their respective Fairy Fountain.

Majora's Mask
In Majora's Mask, the five Great Fairies have been split into pieces by Skull Kid (wearing Majora's Mask). Link must gather them up and take them to the shrine to "repair" the Great Fairy, who will aid him in his quest to save Termina.

The first Great Fairy in Termina is found in North Clock Town, and only one Stray Fairy is missing. It is found in the Laundry Pool in the daytime and in East Clock Town at night. When healed, she either gives Link the Great Fairy's Mask or a magic meter, depending whether he is Deku Link or his normal self.

The other Great Fairy Fountains are in the four cardinal directions, where each Great Fairy is missing fifteen Stray Fairies, which can be found in that area's dungeon. Each time a Great Fairy is healed for the first time, she rewards Link with a helpful item.

Oracle of Ages
In Oracle of Ages, three stray fairies must be located in the Fairy Woods in a hide-and-seek game. When Link is successful, the fairies straighten out the Woods, allowing Link to reach the Wing Dungeon.
