Don't transport these pigs in a blanket warm with a covering. The heat of the food will create condensation with a covering and make the dough wet and soggy. I recommend transporting unbaked so you can bake them when you arrive to a destination (they don't take long to bake) or transporting with a cloth over top of the serving dish. The cloth will soak up some of the condensation so the dough doesn't get too wet.
