Mix thawed punch mix, sherbet, and soda together. Set aside.

In a small bowl add sugar. Add a few drops of green food coloring, stirring until evenly combined.

When your sugar is satisfyingly green, dip the rim of a glass into water. You just want to get the rim wet. Dip the rim of the cup immediately into the bowl of sugar. Remove and set sugar-coated cup right side up. Repeat for the number of cups you're using.

Add desired amount of punch to each cup, and if using add 1 maraschino cherry to each glass for the Grinch's heart that was 3x too small.
