Argorok

Boss of City In The Sky, Twilight Princess's seventh dungeon, Argorok is an armored, fire-breathing dragon. To defeat Argorok you have to use your Double Clawshots to climb up onto a wall and dodge the fire that Argorok attacks you with. After he uses his attack he will be too tired to defend him self. It's at this point that you have to attach yourself to it's tail to and attach your Iron Boots to bring him down and smash some of his armor off. After a few times he will remove all of his armor and fly even higher then normal. Once you reach the top of one of the walls with your Double Clawshot you have to attach yourself to a Peahat. Target the Peahat next to you and just before he attacks you with fire again, move to the next Peahat in line and keep doing this, going around in a circle until you reach his back and attach to his back and hit him as many times with your sword. He will eventually fall and repeat the process again. Occasionally he will switch up his direction and you'll have to go the other way. But eventually he will be defeated giving you the final piece of the Twilight Mirror.
