From publisher blurb:
Beavers, wombats, wolverines, rat kings, 100-foot-long rabbits, capybara . . . pests and pelts of all stripes to fill out your OSR bestiary. Is Rat, Giant really sufficient for your delve into the sewers?
Contains 73 specific animals, a table for quickly estimating furry pest 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.
