1 oz of Pineapple Juice
1 dash of grenadine syrup
1 oz of Midori melon liqueur (or watermelon liqueur)
1 oz of Malibu coconut rum (or Coconut Rum)
Pour the Midori melon liqueur, Malibu coconut rum and pineapple juice into a collins glass. Top with grenadine, little enough not to be able to taste it distinctly. Stir slightly.
