The mane six are summoned to Manehatten by order of Princess Celestia, in order to investigate reports of unusual paranormal activity occurring within the city. But when Fluttershy becomes targeted by a demonic entity, will the power of friendship be enough to save her? Or will more drastic measures be needed? ((Loosely based on the first Ghostbusters film, with scenes added and arranged to be more 'pony-friendly'.))
