Great Fairy's Mask
Attracting Stray Fairies
The Great Fairy's Mask is one of the 24 Masks in Majora's Mask.
The Great Fairy's Mask can be acquired at any point after Link learns the Song of Healing and receives the Deku Mask.
The Great Fairy of Magic in the Fountain in North Clock Town bestows the Great Fairy's Mask to Link when he returns the single Stray Fairy from Clock Town to the Fountain while he is in Hylian form. The Stray Fairy is located in the Laundry Pool in South Clock Town during the day, or floating near the pole in the center of East Clock Town during the night.
When in dungeons, the Great Fairy's Mask shimmers when Link is in a room that contains Stray Fairies. If the Fairy is floating freely (not contained in a chest, jar, or bubble), the Great Fairy's Mask makes a small chime and attracts the Stray Fairy to Link automatically.
In Majora's Mask 3D, it also attracts Fairy Fish in the Ocean Fishing Hole.
