During a sweet summer in Ponyville, something terrible happens. A hurricane ravages the land, stealing ponies with it. Of course - no other pony sees anything too odd about this. As the weather becomes increasingly weird, Vinyl Itch and her coltfriend Tranquil Sky take a walk, only to find themselves with the other ponies, as a new enemy, and an old foe returns, with new tricks up his sleeve. Will these ponies be able to surpass all expectations?
