I just had to look this up. Apparently, snakes can brumate* in cold months, hidden in protected dens from harsh weather. They live on every continent except Antarctica. Not Ireland, of course, because St. Patrick. Who also chased them out of Iceland, Greenland and New Zealand. Basically, everywhere that ends in "-land". Well, not Finland, I guess. And patron saint of Engineers! Patrick, that is, not snakes.

*This is a real word! It's like hibernation, except different to people who really care about the difference. So I guess that's another superpower this cold-blooded nightmare fuel has.
