For the glass, add a rim of frosting to the glass, and dip into the green sprinkles.

For the shake, add ice cream and milk to your blender and blend until smooth.

Add a generous amount of the gel food coloring and mix until combined.

If your shake is too thin, add more ice cream, or if it is too thick, add a splash of milk, and blend until you get your desired consistency.

Pour into your glass, and top with whipped cream, red sprinkles, and a maraschino cherry.
