The Shroom Lord is a larger version of the Fungus Guy. His cap doesn't quite block his vision and his large daunting face can easily be seen. His cap is formed in three parts and unlike his smaller brethren, will perish without it.
His form of attack is a sneeze which fires mushroom caps in your direction. His booming voice will cause rocks to tremble from above. He also has a a large stick that he will swing in your direction. To defeat this monster, three well aimed fireballs toward him will send his cap flying and end his reign.
