Instructions:
Make the pina colada mix as normal with the rum then pour into large shotglass put maraschino cherry on top then take grenadine in a siringe and squirt a few times just on the inside of the shot glass. It wil bleed down and make the effect of a blood shot eyeball with the maraschino being the center pupil. Pretty cool drink for parties and stuff. I always make them on Halloween. Enjoy
