Add the blue curacao with 1/3 cup of crushed ice to a blender, and blend until slushy. Pour the creme de bananes, Malibu rum and pineapple juice into a cocktail shaker half-filled with ice cubes. Shake well, and pour into a hurricane glass. Pour the slushy blue curacao over the back of a spoon into the glass. Garnish with a pineapple wedge, add blue straws, and serve.
