Gaugau

Windowpains are a type of enemy that appears in Wario Land II. They are chunky in appearance and bear resemblance to bulldogs. Since they are always leaning out of windows, their whole body is never revealed and it is not clear what they really are supposed to be. They have striped bandannas tied around their heads, so it can be assumed that they are members of the Black Sugar Pirates, lead by Captain Syrup. When Wario gets to close to their windows, they will start throwing an infinite amount of bottles. One hit of these bottles will cause Wario to lose coins and be tossed backwards. Windowpains are usually present in places where the player has to climb narrow platforms, so the thrown bottles act as a great hindrance.
