Well, they don't look that human--they just walk and talk like them. ... Although some don't look like the animals they're closest to. One of my friends is a pink hedgehog, for instance. And interesting in what way? Wait.. was he a hawk, by any chance?

Yes, I'll be helping them get there as soon as they're ready. It's the same with Amphibians, like frogs or geckos, or even fish. They're "cold-blooded" because their hearts work a bit differently than ours, among other things.
