Fill a glass (preferably a rocks glass/short tumbler) full of ice.
Pour in the rum and Blue Curacao, then pour in the midori.
Top it off with pineapple juice.
Stir the top slightly, leaving the blue on the bottom of the glass (not required) – until the drink turns green. I just mixed mine all together. Enjoy!
