From publisher blurb:
You find an awesome creature you want to be your bosom buddy and companion on your adventures but lo and behold, you don't have the means or the information to actually use them. This is where this product line comes into play! We bring new animals or creatures (or previously published creatures without companion stat blocks) and create animal companion rules for them for use in the Pathfinder Roleplaying Game. These new companions will provide interesting, cute, and lovable companions for the travels of your characters or for nefarious use by a GM and their BBEGs. This book adds 10 new aberration companion stat blocks including the akata, bogwid, geomaw, and reefclaw for use with the Elder Voice feat(s) featured in Legendary Hunters and/or Legendary Companions by Legendary Games.
