Onix

Gold
It twists and squirms through the ground. The thunderous roar of its tunneling echoes a long way.
Silver
It rapidly bores through the ground at 50 mph by squirming and twisting its massive, rugged body.
Crystal
As it digs through the ground, it absorbs many hard objects. This is what makes its body so solid.
