The Hot Coal Rhynoc is an enemy located in Frozen Altars in Spyro: Year of the Dragon. He is unique because of his coal piles, which he uses as his weapon by throwing them at Spyro. He also provides a form of comic relief; if you destroy his coal pile, and not him, he will be harmless, and will bend over and 'moon' you. This would be a possible reference to the first game, which also had a 'mooning' opponent.
Like many Frozen Altars enemies, he can be frozen and used as a stepping-stone.
