Combine the vodka, gin, Barceló Blanco, Blue Curacao syrup, lemon juice, grenadine, pineapple juice, and Red Bull in a shaker with a handful of crushed ice.

Shake vigorously until the ice has melted, taking care due to the carbonation pressure.

Pour the cocktail into a highball glass, then top with additional ice.

Add the brown cane sugar and garnish with a slice of starfruit. Enjoy!
