Moguramen

Moguramen (もぐらメン, meaning "mole face"), known in English as Drilling Moles, are enemies in Wario Land 4 that only appear in the underground areas of the level Wildflower Fields. They are moles wearing green and red masks with drills. The drill is the dangerous part of a Moguramen that will hurt Wario. Wario can attack any of the unprotected parts of their body. When stunned, even their drill is harmless, and they can also be grabbed and thrown. A defeated Moguramen will leave a Bronze Coin. Most Moguramen simply move back and forth on platforms, but some are found in places in the soil that Wario can't reach. Those Moguramen drill through the earth and cause spiked balls to jump up that will hurt Wario on contact. By doing a Ground Pound, Wario will cause the Moguramen to leave its place. Afterwards, it will become reachable for Wario and act like the more common members of its species.
