Packrodent

The packrodent is a creature native to the polluted world of Vusstra.

Biology
Packrodents were muskrat-sized creatures with long, thick strands of gray-blue fur and callused black snouts, bucked teeth and webbed feet. They dwell near the mudpots and thermal hot springs, swimming through the mud where they make warren. In the mud they waddle-gallop quite fast and are attracted to bright shiny objects.
