This is apparently something popping up in the non-Amazon Underground version of the Gameloft My Little Pony Game. A Nightmare Night update is on the way, though not much information outside of the image above has been released for it. I'm expecting costumes. I don't think it would be too far-fetched to assume costumes are going to be a thing.
Also Trixie.
Thanks to Weijianong for the heads up.
