Wolfenboss is one of the bosses found in Wario Land 3. He is a wolf-like ghost that can be fought in The Pool of Rain.
Wolfenboss's main attack is to shoot energy balls at Wario. If he is hit, he restarts. To hit this floating wolf, Wario has to wait until he throws a spike ball and wait until a red little monster comes out of it. Then, Wario chooses the right place to hit him so he can bounce off the wall Wario is facing and hit Wolfenboss.
After Wolfenboss is hit two times, his spiked ball attack is harder to avoid, as it bounces around. When hit three times, he falls and causes the cover blocking the way to the green chest to be removed.
