Fill pan molds less than half full. Bake and cool cakes. Tint melted white candy blue and red using candy colors. Mold scarecrows using "painting" method. Refrigerate until firm; unmold.
Cover cake with tip 18 stripes, piping from bottom to top. Position marshmallow on top of cake. Cover marshmallow with tip 18 pull-out stars. Attach scarecrow and icing decorations using dots of icing.
Adding color details to candies makes them more realistic and much more fun! For large areas of color, it's best to paint the melted candy right in the mold before the whole candy is molded using a decorator brush. Or, for very small details like vines, mouths and messages, melted candy should be piped onto molded candies using a parchment bag with a small hole cut in the tip.
