Frostydale is a debatably-habitable frozen ball of rock nearly four times as far away from Sunnydale as Earth is from the Sun. She’s significantly larger than Earth, but has a much thinner atmosphere at sea level. Those seas are frozen solid over the vast majority of the planetary surface, though the balmy tropics of the equatorial zones at least keep them in a liquid state most of the time. Now I’ve swum in Minnesota lakes in spring, right after the ice melts, and I may have even done a Polar Bear Plunge a time or two in my life, so I find those equatorial seashores to be rather refreshing. I bit like coming home, you might say. But my conscience requires that I warn anybody from warmer States like California or Florida against enjoying them. You will not enjoy them, and you will probably freeze off various body parts that you dearly do not want to lose.
