Well worms, the bane of farmers, are a form of giant roundworm that can infest any type of still water. With a soft yet exceedingly slimy body up to two feet in length, ending in a nasty tripartite jaw ringed with grasping feelers, and the ability to launch themselves up to three feet out of the water, removing even one from a body of water is a daunting task, and they are frequently found in significant numbers (2d20 worms). Being generalists in diet, they can thrive in a number of harsh habitats, even underground, and can slowly creep across land to find new waters. Having evolved to live in the foulest of water, they are immune to poison.

It is rumored that the slime of the well worm is desired by wizards for use as an ingredient in certain magical oils that render one immune to capture by grasping and entangling attacks.
