Act 1:
This is the boss for Marble Garden act 1. This drill machine here is no easy guy. When it drops, whack it but be careful of the drill.
Soon, the drill would turn upside down up start to go up to drill the celing. You can now continue whacking it again. But this time, it is safer as the drill is pointing upwards.
The drill then disappears at the top of the screen. However, you know it is still drilling because of the sound it makes and the vibration of the screen. Rock start falling but only the spike in the picture ( left of Sonic ) can hurt you. A few would drop so avoid them.
The drill then falls again and you can start hitting him again........
