A lizard that feeds exclusively on rocks. The more it devours, the harder its hide becomes, until no blade on earth can pierce it.
The rock-fed lizard's hardened fangs can bite through bedrock, granting it access to a wealth of nutritious minerals beneath. The more it devours, the more powerful it grows, and the greater the scope of its consumption. No force can impede its bottomless appetite.
