The Boo Breaker Halloween Decoration ($35) is available through Oriental Trading's website. By attaching the ghost's front half to the outside of your window and the back half to the inside of your window, you'll create the cute illusion of a friendly ghost passing through your home. Made of polyester, the Boo Breaker is able to handle outdoor conditions, and its suction cups make it easy to install and remove at the end of the season.
