Desert Worm

A Desert Worm is a large carnivorous creature, with a round mouth ringed with several rows of sharp teeth. A desert worm has no eyes nor olfactory organs, but it can sense movement on the ground within 20 feet. It spends most of its life burrowing beneath the sands. A desert worm will eventually leave a potential victim alone if it no longer senses any movement within that area. On a natural 20 attack roll, a victim of up to dwarf size will be swallowed whole, suffering 1d6 points of damage per round thereafter. Only one such victim may be swallowed at a time. A swallowed creature can cut its way out by dealing 5 or more points of damage with a small edged weapon such as a dagger.
