Croak Hopper (クロークホッパー Croak Hopper?) is a big frog enemy, carrying a smaller one in its back, that appears in Wire Sponge's stage in Mega Man X2 and Mega Man Xtreme 2. It was originally created to be the mascot and guard of the Weather Control Center and are often found near Weather Crystals. Their behaviour is greatly affected by the current weather: Due to their defective cooling system, the Speed Burner automatically eradicates them, though Magnet Mine and Sonic Slicer are also very effective.
