Zora's Shop

From Zelda Wiki.org

Zora's Shop is located in Zora's Domain in Ocarina of Time. As a child, Link can get inside simply by getting the Bombs from the second dungeon, Dodongo's Cavern, and going up Zora's River to get to Zora's Domain. As an adult, it's a little more difficult to get inside the shop because Zora's Domain is frozen and the entrance to the shop in encased in Red Ice. To get inside he must go to the Ice Cavern and put Blue Fire inside an Empty Bottle. Then he must go back to the shop and release the flame right outside the entrance. In the shop you can, among other things, buy a Zora Tunic which is useful if a Like Like has eaten your previous tunic.
