The boss of level 8, the Ancient Tomb, Ramrock guards the Falling Star, an Essence of Time. He is a large statue-like stone head and hands, which float above the ground. He has several attacks. Defeat him by knocking his fists back at him with your sword, then, during his second form, drop a bomb between his hands when they are open. Finish the third form by ricocheting seeds off the wall to hit the back of his head. Finally, defeat the fourth form by pulling one hand back and letting it snap back to damage him.
