I would def call this just a mellow cocktail if you want to just enjoy a nice drink. It's dynamic looking, it has a lot of interesting flavors. I could see this being made into a serious fish bowl.
1 oz. Spiced Rum
2 oz. Blue Curacao
4 oz. Pineapple Juice
Splash Ginger Beer
Garnish: Pineapple Leaves/Cherry
