The Legend of Zelda: The Wind Waker -
The first stop is one square region north of Outset Island, located at Five-Eye Reef. To the east of Five-Eye Reef, there is a Platform sticking out of the water. These platforms can be found throughout the Great Sea and they give a variety of rewards. Most of them usually have turrets along the outside, as does this one. Link can use his bomb canon to shoot down these turrets. Sometimes Link will get rewards for defeating all the turrets. For this particular platform, that is not the case. Link can just climb on board where he'll find a series of Bokoblins, which is a good place to snatch Joy Pendants. There is a small treasure chest, but it just contains a Golden Feather.
