An easy way to defeat this Boss is to use the spinner and go along the side of the sand pit he is in the middle of until you are directly behind him. Hit the "support bone" which is the spine. To hit the bone you must use the spinner's attack. Each time more skeletons will come up to block you from reaching the spine, but they do not regenerate. If you kill one, the next time you attack there will be a gap in the wall of skeletons which you can slip through and attack. After you have done this three or four times the sand drains and the head of the beast will still remain. Use the spinner to raise the platform. As you walk out, an intermission sequence of the head coming to life and knocking Link off the platform will play. You must use the spinner to climb the platform. After awhile the head will start shooting fireballs at you while you are climbing. The key here is to jump from the platform track to the track on the wall every time he tries to hit you with a fireball. The head will then get irritated and come in beside you, at which time you can jump and attack it with the spinner. When on the ground attack the sword that Zant puts in its head. Repeat this two more times to kill him and get a heart container.
