He can be avoided by going up a rope nearby, and upon a successful dodge he will face plant into the ground. If he comes into contact on his charge he can be a rough fight for this spot in the game, but if the player dodges him they can engage in battle with him still fallen over, making the battle a lot easier.
Climbing up the rope then descending onto him while he passes under you causes his sprite to bug out for a split second and begin the battle with crush's standing form. Upon defeating him, he'll keep running until he crashes. At that point, walking into crush will initiate another fight with his fallen form.
