Fill your glass with ice all the way to the top — the drink is built directly in the glass, and you'll get some dilution as you pour, so starting fully packed with ice keeps it from getting watery.
Pour in the Malibu coconut rum (3/4 oz).
Add the spiced rum (3/4 oz). Any spiced rum works — no need for a specific brand.
Add the Midori (3/4 oz). This is what gives the drink its signature electric green tint.
Pour in the sweet and sour mix (1 oz).
Add the pineapple juice (1 1/2 oz).
Top with the blue curaçao (3/4 oz) — this adds hints of orange flavor and turns the mix a funky blue-green.
Stir gently just to combine into a uniform color. Top off with a little extra ice if needed.
