Rock Worm

&nbsp Rock worms are creatures from Dungeons and Dragons.

Appearence and Other Related Stuff
They look like regular earthworms although they are exorbitantly larger and have an extremely tough hide composed from rock and calloused flesh, which covers them entirely. While not necessarily carnivorous predators, rock worms will hunt and consume other living beings on occasion. This is because rock worms need to sustain their bodies by eating carbon-based organisms as a supplement to what they ingest from burrowing. They can cause many problems when near civilization due to their tendency to burrow, which can destroy foundations, supports, mines, and even pipe-systems. When encountered (and subsequently eradicated), they tend to cause a great deal of damage to the natural and built environments. Sinkholes are highly characteristic of a rock worm infestation. A rock worm is about 40 feet long, 5 feet in diameter, and weighs about 50 tons.
