When the festival celebrating Nightmare Night arrives at Ponyville everypony thought it would be the usual funscary time of the year they had come to love. Foals and adults running in the street and enjoying a night of good-natured fun. What could possibly be better? Surely, nothing could ever ruin such a night.
Unless, of course, an otherworldly unbidden guest made itself rudely present.
