You should mix up your range between godawful candy like candy corn and black licorice and then throw in the occasional full size candy bar like a Snickers or Butterfinger like a total boss.
I don't think you can go wrong with the Twix/Snickers/PB Cup/Butterfinger combo bag thingy they sell. I tell you tho, I always loved Dots growing up so that would be cool with me. You could also go off the board and buy carmel apple pops.
Oh snap that is a great curveball on the treat front. I might have to spring for a few boxes of flamin hot Funyuns to giveaway this year. I freaking love those things.
