The Tongue of Rashvalley

In Rashvalley, there is a gigantic hole, which is filled with unnatural darkness. Inside is the last remaining creature of the frohworms, a subtype of the primitive worms. The frohworms have long tongues that they use to ensare their prey. This creature has fallen into one of the valleys of Rashvalley, which are unnaturally deep. Since then, the creature has made it its home and constantly sneaks its tongue out to terrorize the nearby villages.
