Many a predator in the Mutant Future is drawn to the frail, helpless grizelle as it limps along, alone and terrified and bleating for its herd.  These predators don't live very long.

Found in praries, scrublands, and barren wastes, grizelles appear as slight antelopes of garish coloration that stand in stark contrast to their surroundings.  They hobble about and cry forlornly, seemingly oblivious to danger.  But when other creatures approach and get within 10'...

...a grizelle's mass shifts and its skin ruptures, and a fanged, muscular, gore-drenched beast the size of an Ancient horse bursts forth from within (Surprising on a 1-5 on 1d6).  It attacks in a savage frenzy of teeth, horns, and claws, and its tail barbs inject a Class 1-6 (determined randomly) poison.

Once a grizelle has fed, it shrinks and regenerates its concealing skin, and begins the hunt anew.
