Shunks are 2'-3' long, low-slung creatures with sleek builds, shiny blue fur, and prominent dorsal "fins" made of bone.  Their jaws are filled with rows of serrated teeth.

Upon encountering prey or predators too large to handle itself, a shunk lifts its tail and discharges a cone of bloody mist 15' long and 5' wide at the end (which requires an Ability Check Versus DEX to avoid).  It then trundles off into the brush...

...but in 1d4 turns, every shunk in a 1 mile radius descends en masse in a ravenous frenzy on those coated with the spray.  Such slunk "schools" move at 135' (45'), contain 4d12 members, and have a Morale of 12.

Even if a sprayed victim immediately bathes and washes their gear, 2d12 shunks will still arrive, thanks to their hypersensitive olfactory senses.  Only extracts from select citrus-based Mutant Plants neutralize the scent completely.

The musk's effects last 4d6 hours, meaning further travel beyond the initial radius is a risky proposition....
