Lurk what’s waiting for the Monster High™ ghouls when they bring their killer fashion to the howlways of the spooktacular Haunted High! When the ghouls of Monster High ™ follow Spectra Vondergeist™ one day, they discover a creeperiffic Ghost World with an all-spirit school. But their scary-cute student bodies are hardly welcome with the very strict Principal Revenant, and she punishes Spectra with frightful detention chains that prevent her from re-joining Monster High ™. Now, it’s up to the imperfectly perfect friends to take on ghostly forms in order to save one of their own from disappearing forever!
