Prepare the strawberries. Wash and dry the strawberries thoroughly and allow them to come to room temperature.
Melt the candy melts. In separate microwave-safe bowls, melt the orange, black, and white candy melts according to the package directions. Do not overheat, or they will become hard and clumpy.
Dip the strawberries. Hold a strawberry by the green top or use a skewer to dip it into the melted orange candy melts. You can either coat it fully or leave red "shoulders." Repeat with black and white candy melts as needed for variety.
Decorate. Using a toothpick, draw a face on the dipped strawberries for jack-o'-lanterns. For ghosts, dip in white candy melts and add candy eyes while the coating is still wet. Use the black candy melts for additional decorative details, such as mummy stripes or other spooky designs.
Cool and set. Place the decorated strawberries on parchment paper and let them cool until the candy hardens.
