"Yeah, there's a bunch of - I forget the real biology word, I just think of them as factored-out. Cats, hawks, spiders - there's polar bears at the south pole, but they're different from bears like Bosco, I don't think there are any regular animals that have a plain-bear and a polar-bear kind, like there's polar bear dogs but no bear dogs and lynx bears but no polar lynx bears. But Bosco was a one-off as far as anybody can tell, and cats and hawks and spiders and polar bears are all real established species."
