From publisher blurb:
Goats, sheep, horses, rhinoceroses, elk, centaurs, triceratops, hippocamps . . . herd animals and ungulates of all stripes to fill out your OSR bestiary. Is Animal, Herd really sufficient for your trek across the savannah?
Contains 86 specific animals, a table for quickly estimating ungulate statistics based on animal weight, and a small selection of rules and conversion notes for using the book.
About a Wretched Menagerie: Written in a compact (some would say cramped) style with minimal fuss and no art, each manuscript in this series covers a narrow niche of creatures. Tools for estimating statistics based on size and ferocity, rationalized statistics for a wide variety of real world (and fantastical) creatures within the niche, and a small selection of extra rules will be standard for each.
