Where is volcano island on Zelda wind waker?

First off, there are a couple fairy Islands in wind waker. They are all shaped like hearts, and you need to do different things to get inside them. One of the islands that I can remember right now is just north of Tingle's Island, and it gives you a rupee sack upgrade, allowing you to hold 1,000 rupees instead of just 200. not sure what you need to do to get into this island, though. Another rupee sack upgrade is on your hometown island, but you need bombs to get into it. I hope this helps you, recommend me if it did. (posted by Darke, member of WikiAnswers since 4/29/08)
