Stray Fairy

Stray Fairies are representations of portions of a shattered Great Fairy. 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, the five Great Fairies have been split into pieces by the Skull Kid, who is under the influence of Majora's Mask. Link must gather them up and take them to the shrine to heal 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 Magic Meter or the Great Fairy Mask, 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 that 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 or an upgrade.

The color of the Stray Fairies depend on the Fountain they belong to:

Oracle of Ages
In, red, blue, and orange friendly but mischievous Fairies have the power to jumble up the topography of the Fairies' Woods as they see fit in Labrynna's present. Link must locate the three Fairies in a Hide-and-Seek game to be granted access to the Wing Dungeon. When Link is successful, the Fairies straighten out the Woods, allowing the young hero to reach the dungeon.

If the original file is linked to Oracle of Ages, after Link talks to the Stray Fairy in the rubble of the Wing Dungeon, the Heart Ring L-1 can be found in a secret room behind the waterfall of the Temple of Seasons.

Four Swords
In, in addition to Fairy Spirits, Stray Fairies appear in the Chambers of Insight at the beginning of the game, and provide the Links with their advice on how to progress.

Trivia

 * Symbols that appear on Switches in the Chambers of Insight from Four Swords and the Jabber Nuts from slightly resemble the head of Stray Fairies.
