1Heat oven to 350°F (325°F for dark or nonstick pans). Place paper baking cup in each of 24 regular-size muffin cups. Make and bake cake mix as directed on box for 24 cupcakes. Cool in pans 10 minutes; remove from pans to cooling rack. Cool completely, about 30 minutes.
2Frost cupcakes with vanilla frosting. Pipe designs on cupcakes with yellow and green icings. Decorate as desired with candy sprinkles.
3With toothpick, poke hole in side of each cupcake. Tie ribbon bow in center of each lollipop stick. Add gumdrop to one end of each stick. Insert other ends of sticks into sides of cupcakes, just below frosting, to form rattles. Store loosely covered.
