1Heat oven to 350°F (325°F for dark or nonstick pans). Make and cool cake as directed on box for two 8- or 9-inch rounds. For easier handling, refrigerate or freeze cake 30 to 60 minutes. Cut one round as shown in diagram.
2Arrange pieces on tray as shown. Attach pieces with small amount of frosting. Frost with a thin layer of frosting to seal in crumbs. Refrigerate or freeze 30 to 60 minutes to set frosting. Frost entire cake. Sprinkle tie with colored sugars, and outline with shoestring licorice.
3Arrange cake balls on frosting for cheeks. Insert short strips of shoestring licorice into cheeks for whiskers. Outline eyes with shoestring licorice; add short strips for eyelashes. Use black gumdrops for pupils of eyes, pink licorice candy for nose, red gumdrop for mouth and gum for teeth. Cut striped gum into narrow pieces and place in centers of ears. Decorate with magician's hat and magic wand if desired. Store loosely covered.
