Do humans and anthro animals live on the islands where the classic games take place? I mainly think it's humans on Little Planet, South Island, and West Side Island, due to the amount of urban and industrial areas. Plus, Tailstube says that the animals live on the small islands, Little Planet, is, well, a planet, not an island. There are also distinctly human environments on the classic islands too (Spring Yard, Chemical Plant, and Metropolis to name a few). I can take criticism. I also say this cuz it looks like the anthro animals do not care about industrialization/urbanization to begin with, rather, relying on imports and exports from human nations
This is just my goofy ahh opinion. Feel free to explain it to me on this post.
