Cave Worms

The Cave Worm of Mars is truly a disgusting creature.

Description
This absolutely featureless worm waits in the dark mines of Mars, giving off a light glow to attract prey. Once it spots a target, it shoots off spikes or tries to grab the victim with its tentacles to melt it with acid. However, these worms are easy to deal with if the adventurer is careful enough and kills them from afar with projectile weapons.

Cave worms are usually found within dark caves on Mars.
