Attack 1: The boss will hit his hand down twice allowing you to get 2 hits on his arm each time he hits them down
Attack 2: the boss will detach both "hands" and send them at you and they both start going around the battle arena in a certain direction. when they do this use your boost and catch up with the furthest one and hit it from behind and you will get the yellow drill wisp
Attack 3: the boss will sit down on the charge icon and start spinning VERY fast around the arena. its almost impossible to dodge this above ground. this is where you use the wisp and dig under the battle ground and hit the 2 round mine looking things when they are yellow DONT hit them when they are blue or you will get hurt.
once you hit both yellow mines the boss will fall over and you simply hit his head and finish him
