Something is drinking the blood of ponies in the dark of night. A shape that Twilight had thought long cured has been seen, is she the culprit?
This is something I'd came up with as a Flutterbat followup episode after her first appearance. The Star Wars reference in the title is irrelevant, I just liked the sound of it.
Just some advanced warning, there's a hint of Flutterdash towards the end, couldn't help myself.
