Take the very large marshmallows. Cut the corners off the bottom to make them look like diapers. Cut an opening in the top of the diaper. Use a decorating bag with a small tip, or use a sandwich bag with the corner snipped, to fill the diaper with melted caramels or caramel sauce. You can serve lemonade with them to have a *matched set*. You can say they are Monster Pee-Pee and Dracula’s Dirty Diapers.
