It is a species of frog in the World of Reptiles that is mostly green...and if he looks out from his exhibit he might see a reticulated python, anaconda and Burmese python.
Good guesses. Here is one last hint: it is a frog, in the beginning of the World of Reptiles in the Asian Amphibian habitat. And if this frog had a taste for human food he would have easy access to Pho!
wow bigfoot410 that was really good and never would have thought of that! I have to say though, i am not so good with amphibians anyway... so cloudedelopard it's now your turn
