What could be freakier than hundreds of these rabid little blood suckers swarming your Halloween scene? Room roll with gloomy greenish-blue background and black flying bats measures 48 inches wide by 50 feet long. Create your own custom haunted house with ease by stacking two different room rolls wherever you dare. Then add on a few final torturous touches with the larger Scene Setter decorations (like the Graveyard Raiders Scene Setter, Item #1006114).
