In advance: Prepare candy shells in baking cups. Attach nougat candy feet to bottom with melted candy. Let set. Also: Mold reindeer heads using painting or piping method and Christmas Character Lollipop Mold without lollipop sticks. Fill cup with Chocolate Mousse; use spatula to smooth and round top.
Attach reindeer head to edge of candy shell with melted candy; refrigerate until firm. Attach large chocolate chip in back for tail.
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.
