Stage Monsters are enemies that appear in Studios. They come in three variants although there is no any difference between them.
These creatures appear to be cardboard cutouts resembling various movie monsters, the exception being they are covered in blood and veins, with an actuall heart located on their back, being their weak spot. They move relatively slowly, so attacking them from their back shouldn't be a problem, they are, however, noticeably more resistant to frontal attacks then other enemies. They attack by falling at the player. As they are mostly made of cardboard, they often gib after death.
The texture used for the Vapire Stage Monster depicts Count Orlok from the 1922 horror movie "Nosferatu, eine Symphonie des Grauens".
