The Australian green tree frog has big eyes, a friendly demeanor, and a bit of a pot belly, all of which bring to mind certain traits of Muppet star Kermit the Frog. Both are popular human companions, too, the former as a pet, the latter as a familiar character of television shows and movies. And so, I began to wonder what else the puppet and his Australian cousin might, or might not, have in common.
