A monster that resembles the head of a sandworm, it attaches itself to cave walls and waits for unsuspecting prey to pass by. It then expands its neck from the place its attached to and swallows its prey whole. Instead of digesting their flesh, however, its digestive enzymes target anything made of metal, so it will digest your currently equipped armor and weapons over a long period of time before spitting you out and leaving you completely unarmed. Afterwards, it seems to just leave you alone.
