Start by pouring the 1/2 oz. of gin into your glass. Then, add the Jagermeister. Fill the rest of the glass up with standard Blueberry Cocktail mix (as a side note: the Blueberry Cocktail mix is non-alcoholic, so it can be found at your local grocery store if your place of liquor purchasing does not have any in stock). Watch as the drink turns an odd green! Toss in a cherry to simulate the 'red planet'. Serve.
