Rasping Sandworm

Evolved from the Beach Thornworm in areas where plents had out competed the sand-growing algae the rasping sandworm burrows underneath resting plents and bores a hole in their base with its rough tongue-like mouth part. Lacking pain receptors, the Plent will be oblivious to this attack and simply allow itself to be eaten. The Elevated Plent is, of course, immune to such attacks. The sandworm reproduces by laying eggs produced within its body in the sand nearby the remains of dead Plents, to give its young a good start in life.

Note: The Burrowing Thornworm still exists in areas where Plents are not plentiful (a-ha)
