This Giant Ape may seem like a puzzle when you first come into the fight but is quite simple. Simply use the flamarangs and hit all of the fire on its body to burn it to end phase 1. Phase 2 you need to use the pilot lights around the map to turn the flamarangs into small missiles. Simply aim at the gass and throw the rang at fluffy a few times to end phase 2. Phase 3 is simple as well. Equip the ice rangs and go around the back of its head where the fire is. Hit the fire a couple of times and the fight ends.
