There are 2 phases to defeating Argorok (it looks like a dragon). (phase 1) Go to the side of the platform then put on your iron boots. Clawshot back and forth (gradually going upward) between both of the poles on the side of the platform. Once you get to the top of one of them, Clawshot Argorok's tail. (Make sure your iron boots are on). Do this twice until all of its armour is off. (phase 2) Grapple back and forth between the poles going upward again. then clawshot one of the plants that are flying. Hold the L button and keep clawshotting to the next plant. Argorok will spit fire at you but just keep going. Once Argorok is done spitting fire keep clawshotting the plants. Then once you're behind it, clawshot its back and attack it with your sword. Do this 3 times and it will die. The third time you do this it will spit fire at you twice. The second time right after the first time it spits fire at you, switch directions (cause it will try to burn you by spitting fire at the plant ahead of you.
