This is Buzzar. He guards Mt. Rugged. Wow! That's one big bird! If you get caught in the clutches of his sharp claws, you'll lose 4 HP! Try to wriggle out of his grip. His special attack is flapping his wings to create wind. This attack damages your party members, too. But he was hatching eggs, wasn't he? Is it possible that he's really a she? I wonder...
