Makenzee (Sorry I don't know how to spell Makenzee right)
Megaton Hammer his nose, then use the Sword on his head
Use the Lens of Truth to see his heart, and Bow n Arrow his heart.
When the boulders fall down on you, use the Golden Gauntlet on the boulders, and when he comes down throw the boulders at him.
Rip his head open with the Biggoron Sword 20 times
Use a Silver Gauntlet to magnet his head, and then to control him, and smash his head up and down on the ground like heck!!
