Creating a mega evolution every day until Pokemon legends z-a comes out – Day 20: Mega diggersby

Mega diggersby digs by rapidly spinning on the iron ball on the bottom, elevating itself in the air by pushing its tail forcefully on the ground, and flipping upside down midair, which proves to be efficient for fast digging. The iron content in the dirt that's on mega diggersby is duplicated after mega evolution, causing its ears to acquire sharpness and toughness.
