The Legend of Zelda: The Wind Waker -
Pieces of Heart help you to gain more life, therefore making your quest easier and more manageable. You will need four of these pieces to receive another heart in your life meter. Once you get the Piece of Heart, head down the hallway towards the Moblins and get caught by them. Getting caught is easier than making our way back to where we need to go, so if you fall down or get lost, get yourself caught and continue from where you were.
