Fairy Woods

From Zelda Wiki.org

The Fairy Woods are an area found in Oracle of Ages next to the sea. Similarly to the Lost Woods, they change according to what area you're in and which direction you decide to go. The Fairy Woods contain a Hide 'n' Seek game in which you have to look for three Stray Fairies, that are similar in appearance to those that appeared in Majora's Mask. When you beat the fairies at their game, they set the forest back in order so that you can make your way to the Wing Dungeon.

Later on in the game, one of the animals will become lost in the woods. Which one it is depends on if Link has a Strange Flute and which flute he has. Once Link finds the animal, it will become Link's companion and he will receive the corresponding flute.
