In a cocktail shaker filled with ice, add the vodka, orange liqueur, gin, white rum, blue curaçao, raspberry liqueur, and sweet-and-sour mix. Shake well.
Strain into a chilled highball glass filled with ice.
Slowly drizzle a little extra raspberry liqueur over the top to create a layered effect. Garnish with a lemon wedge and a maraschino cherry. Serve immediately and enjoy your cocktail.
