Robobird

Robo Birds (ロボバード, Robo Bādo), known in English as Drill Bat, are enemies in the game Wario Land 4. As its name implies, it is a robotic bird. It only appears in the Hard and Super Hard modes of the game. Robo Bird is blue-gray and has a drill for a nose. Robo Bird flies in a straight line (and even through walls) with its jet pack. Robo Bird can only be defeated by a stomp to the head by Wario. Robo Birds appear in the Ruby Passage.
