Helmasaur King

The Helmasaur King guards the First Crystal in the first dungeon of the Dark World in A Link to the Past. He is a large quadrupped creature with a large shield on his head. Before he can be damaged this shield must be destroyed with the Hammer or the Bombs. Under it appears a large green jewel on his forehead which can be hit with the arrows. When he is defeated he leaves a Heart Container and the First Crystal in which one of the seven maidens is prisoned.
