Make pudding as directed with the ¾ cup of milk. Combine pudding and creme de menthe in a bowl. Mix until combined. If you don't think it is green enough put a small amount of food coloring in.
Pour into individual servings, such as paper cups or condiment containers. Let set up in the fridge
Put cool whip on top before taking if you desire.
