Frost cupcakes with remaining frosting. Press 1 coated cookie onto each cupcake so cookie extends over edge of cupcake to look like snout of moose. Poke 1 pretzel half into each cupcake, behind cookie, for antlers. Use white decorating icing to pipe on nostrils. Use red decorating icing to pipe on mouths. Attach blue candies for eyes and brown candies for ears.
