Goron Bracelet

The Goron Bracelet is an item obtainable in Ocarina of Time as Young Link. After arriving at Goron City, Link must play Saria's Song for Darunia to lift him out of his depression. After doing so, Darunia will give Link the Goron Bracelet, allowing him to lift up Bomb Flowers, which he can then use to blow up the giant rock blocking the entrance to Dodongo's Cavern.
