Remove cake balls from freezer. For each pop, dip tip of 1 lollipop stick halfway into melted candy and insert stick halfway into 1 cake ball. Place on lined cookie sheet until all sticks are attached. Dip balls in red or white melted candy until well coated; tap off any excess. Decorate with sprinkles, red sugar or opposite color of coating, as desired. Poke ends of sticks into foam block. Let stand until set. Store at room temperature.
