You can probably tell I altered it a little structurally, for my ease of drawing and structure-function sense: - Metal helm and plates are over bone; outer teeth - Inner teeth stem from actual skeleton - Rock-like scales, not actual rock - Head more dragon-like (snout) - Tongue is orange because sure, why not If it was made only of metal, that had better be some strong stuff because lava is really really hot. And rocks just break easily and would probably melt in lava.
