Is it by any chance the brow antlered deer they're fairly large in number more so than the tree shrew
If you think harder, and perhaps check the map of the zoo, you may see the way ahead.Go the way of the smallest animals, to the tsavo aviary or to the butterflies, both contain species large in numbers and smaller than the elephants for sure.
Water Dragon wins by a short head from Charlie S who was heading in the right direction (and I was doing my recycling).If you look for us at the zoo, you don't need to go on a journey, just look near the elephants (but we're much smaller than they are).
