One of the first robots you save is Cosmo Bot, a Russian robot whom Botley says he didn't get along with until recently. Of course it makes sense, considering the Soviet Union broke up five years before the game was made.
Botley mentions that the mountain is entirely self-sufficient. So why does Polly go to a school with other people instead of just being homeschooled? Two reasons - first off, it's to give her some socialisation with other kids her age. And the other (and probably main) reason? Because she screws with all the robots.
Although given the real-world events between America and Russia since The New '10s, what would the relationship between Botley and Cosmo Bot be like today?
