Every so often, a storm comes along that even the Pegasi can't control. Best they can do is warn everypony to bunker down and ride it out. Equestria hasn't seen a blizzard this bad in over half a century. AJ and Big Mac were out when the first winds hit, so Applebloom's stuck with Granny Smith in the farmhouse.

But ol' Granny remembers, she tells Applebloom. She remembers the last blizzard, and what came with it. Can't help but wonder if they'll stop by again.
