As it grows, the stone portions of its body harden to become similar to a diamond, but colored black.

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.
