Stone Watcher

Stone Heads are enormous boulders found in The Wind Waker. They are five times Link's size and impossible for him to lift unaided and the Stone Heads cannot be destroyed by Bombs, like regular rocks can. The Power Bracelet, the treasure of Fire Mountain, gives Link enough strength to lift these gargantuan rocks, similar to the power of the Silver Gauntlets in Ocarina of Time. There are only four Stone Heads located on the Great Sea: one on the aforementioned Fire Mountain (blocking a shortcut to the exit), one on Stone Watcher Island, one on Outset Island blocking the entrance to the Savage Labyrinth, and the last one at Headstone Island blocking the entrance to the Earth Temple.

Trivia

 * The face portrayed on the boulders mildly resembles that of Ganondorf; it is possible that he created the boulders in his likeness.
 * Head Statues that appear in Phantom Hourglass and Spirit Tracks resemble the Stone Heads.
 * These rocks also appear in several test rooms which can be only accessed with action replay.
