Fairy Fountain

There are two types of Fairy fountain, ones that give you new moves or items, and ones which contain Red Fairies which revive Link after he loses all of his hearts. In Ocarina of Time, Link learns three spells from the fairies, Din's Fire, Farore's Wind and Nayru's Love.

In Majora's Mask, Link must find the lost fairies in the dungeon, with the help of the Great Fairy Mask, to rebuild one of the fairies to give Link new items, eg. the Great Fairy Sword.

In Wind Waker, the fairies give Link larger containers for his weapons, like larger quivers and Bomb Bags.
