1. Put 1 maraschino cherry in each section of an ice-cube tray, then fill with cran-raspberry juice. Add 2 drops red food coloring to each section, and freeze.
2. Mix 2 parts orange juice and 1 part ginger ale in a pitcher, and set aside. To create blood, add red food coloring to some corn syrup.
3. When ready to serve, dip the rim of each glass into the syrup, and allow it to drip down the sides. Fill with punch mixture and add 2 maraschino ice cubes.
