Din's Fire, Farore's Wind & Nayru's Love
Din's Fire: In Hyrule Castle as a Kid, from the Market, past the gate is a rock in the far corner - blow it up with a Bomb and crawl in the hole to get to the Great Fairy's Fountain; now play Zelda's Lullaby on the symbol and the Great Fairy will appear to give you Din's Fire.
Farore's Wind: In Zora's Fountain as a Kid, from Zora's Domain, go to the right of Jabu Jabu, through the water and over to the shore at the other side; in the lower right hand corner of the map, Bomb the wall to reveal the Great Fairy's Fountain - go inside and play Zelda's Lullaby to get Farore's Wind.
Nayru's Love: In Desert Collosus as an Adult, from Haunted Wasteland, there's a crack in the wall between some trees along the right side; Bomb it to reveal another Fairy Fountain, play Zelda's Lullaby as usual and you'll get Nayru's Love.
