Wash watermelon under cool running water and pat dry. On cutting board, place watermelon on its side and use kitchen knife to cut off 1/4- to 1/2-inch from bottom (end opposite stem), being careful not to cut too deep into white part of rind.
Cut 1/2- to 3/4-inch from stem end to create an opening large enough to fit a small bowl.
Using the dry erase marker, draw eyes, nose and mouth, along with wavy slits around carving to let more light flow through. Use paring knife to cut out design, being sure to cut through to red fruit. Use fluted or regular melon-baller to hollow out inside of watermelon. Use scoop to remove excess watermelon.
Peel green rind off outside of watermelon. (Tip: Different peelers work well for different parts of the watermelon, depending on how flat or round the melon is.)
Wrap thin strips of cheesecloth around mummy carving and secure with straight pin, if needed. Put battery-operated candle or light into carving. Fit small bowl into top of carving and trim away excess rind to make bowl fit securely.
Fill bowl with melon balls and attach candy or blueberries to make eyes.
