Blue		 As it grows, the stone portions of its body harden to become similar to a diamond, but colored black.
Yellow Burrows at high speed in search of food. The tunnels it leaves are used as homes by DIGLETTs.
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.
