Let’s start with a simple, inexpensive game: Pin the Face on the Pumpkin.
First, it’s really taping the face on. No one’s trusted kids with actual pins for a few decades now.
Second, you can use a real or fake pumpkin for this -or even a giant picture of a pumpkin.
And for a final tip, think how easy it would be to jazz this up for that trying-to-show-off problem we all have. You could do lifelike body parts, fun accessories, or hair.
