Although the body plans varied wildly in their details, the creatures I was seeing did tend to fall into familiar patterns. Insect analogues were, so far, six-legged and exoskeletal, and seemed to hit a maximum size of slightly larger than a mouse. I found a small, furry mammal analogue that had six legs as well, except for one variant that had four legs and wings. I decided to name this particular animal a hippogriff, harkening back to my D&D days. This particular little beastie seemed to have limited ability to change color, to match its background. I watched with amazement as it blended into the tree branch and waited for prey to pass by.
