It's a bat attack! Well, actually, it is only a ceiliing decoration. The Bat Attack ceiliing decoration covers about a 12' long x 1' wide swath of your ceiling with a translucent plastic purple forest (as you would see it looking up), and descending down (between 15" and 20") are a multitude of plastic foil bats. Two plastic bars with strings attached are at either end of the decoration to help you hang and straighten it... or roll it up a little bit to fit smaller rooms.
