Everyone is acting like this a mouse, a duck and a dog, all human-sized, walking and talking and workng as Ghostbusters or whatver. Again, each "borough" of Zootopia corresponds to an ecosystem where the appropriate animals live (e.g. polar bears in Tundra Town). The animals maintain a lot of their natural characteristics--the mouse is tiny, the rabbits have dozens of kids, the sloth is slow. SPOILER, but the whole plot of the movie relies on the underlying tension between former predators and prey. While I'd rather TLK, to me this is a far better fit to a broad theme of "animals" than watching a drum circle from Planet Cultural Appropriation.
