Stone Watcher Island
So tell me, small fry, have you heard about
The water is
Stone Watcher is a small island located two blocks to the West of the Private Oasis in The Wind Waker. At first glance, this island seems to be useless; small with little foliage and only a Stone Head in the middle. Once Link obtains the Power Bracelet, however, he is able to lift up the Stone Head and reveal a hidden cave full of monsters. If Link defeats all the monsters, a treasure chest will appear that contains the necessary Triforce Chart #7. There is also a Piece of Heart on a platform east of the island, but Link can only get it after he defeats the Bokoblin and the cannons on the wall guarding it and the island.
The Blue ChuChu can be found behind the large boulder.
