In practical terms, they would have to live either underwater or underground for the real estate. Underwater, it would either be some variety of octopus, which we would make an enemy of almost immediately, or a cetacean, which would be poached to extinction within a few years. Leave the octopus alone, approach the mammal and advise them to swim the fuck away. Quickly. I’m not sure what might be stewing underground and I’m not sure I’d want to know.
