Great Fairy (Oracle Games)
If Link has already saved the land of Holodrum, he can encounter a special Great Fairy located around the remains of the Wing Dungeon in the Fairies' Woods in the Present. She appears shortly after completing the Wing Dungeon in the Past, and gives Link a secret to take to Holodrum and tell to the Great Fairy behind the waterfall in the Temple of Seasons.
A special Great Fairy can be found in a Linked Game, located in a cave just east of Snake's Remains. This Great Fairy plays an essential role in the Tingle Secret, which leads to Link getting a Seed Satchel capacity upgrade.
