Every Trick or Treat Street needs a house at the end of the block with all the lights on. This one shows up as an air-filled mylar balloon, a purple haunted house with glowing windows and a bat or two circling the roof.
Prop it by the door, float it into a photo backdrop, or cluster it with the rest of your Halloween balloons for a whole spooky skyline. Air-fill only, so it stays standing from the first guest to the last.
