Pizza Creepers

I made this for a friend who works as a delivery boy at a pizza franchise, Pizza Capers. My idea is that instead of hiring delivery boys, the pizzas could be taped to creepers. As night falls the creepers will be drawn naturally towards people in their houses. It is a cost effective albeit broad range system.
Just imagine. There's someone at your door and you smell delicious pizza ... but it turns out to be a creeper! BAM! NEVER TRUST THE PIZZA BOY.
