On a perfectly normal day in Ponyville, a strange, mute, relentlessly obedient creature appears. Strange happenings ensue.

Twilight is enjoying a perfectly normal day in Ponyville. The sun is shining, birds are singing, and everything is perfectly fine.

That is, until a number of strange, mute creatures appear, who seem hell-bent on attacking each other for no reason whatsoever.
