What do you do when you have moved the head on outset island?

You have to get Power Braclets to move that rock. They're located at a Fire Mountain that is one square south of Dragon Roost Island. But before you can even get in the vocano you have to freeze the lava. That's a job for the ice arrows. They're located inside Mother and Child Isles by using the tornado (Ballad of Gales). To get this song for the Windwaker, you'll have to fight Cyclos with the arrows you have. You can find him in Northern Triangle Island, inside the large tornadoes. Just aim directly at him and it will hit him. Do this three times or you will lose and will be carried of into a different, random area.
