Maybe a bat? If humans are to mammals, as storks are to reptiles (stork=bird=reptile). Then you would have to do the converse and have a mammal deliver the little chameleon babies, hence, a bat (the only mammal capable of flying). I keep imagining a tiny little bat carrying around a minuscule cham wrapped in a small white cloth. Kinda satisfying.What would the cham equivalent of the stork be?
