They were super excited. That afternoon we went to Target and got goodies for our own treat bags and they came up with a list of people to hobgoblin. We bought vampire teeth, pumpkin erasers, Halloween tattoos and a bag of candy, and put together the bags. Since Little Man's friends are not in our neighborhood, I sent an email to the parents of his friends letting them know that the identity of the "Hobgoblin" is supposed to be a secret, but I wanted at least them know who the mystery candy came so they'd feel comfortable letting their kids have it.
We drove from house to house dropping the treat bags in mailboxes or on the front steps with the kids name on them. Sometimes they would ring the doorbell but mostly they just made the drop and then got back in the car as quick as possible in a fit of nervous giggles. We were only caught once. Little Hugger was dropping off at a friend's house when her friend's brother opened the front door and told her Little Hugger was there. Little Hugger froze in the driveway - unsure of what to do. I told her friend we were trying to surprise her, so close her eyes. She went inside, Little Hugger dropped the bag on the steps and we drove away.
It's a fun little tradition, doesn't cost much , so if you think your kids would like it I encourage you to give it a try (you could always plant the first bag on your own doorstep to get it started). Our sign is a little blurry after being recopied so many times so I encourage you to make your own, but feel free to use our words. I would love to start an adult version with seasonal beers/wines other treats
