In a blender container, combine all ingredients except ice cubes and mint and blend on high speed until frothy. Pour into four tall glasses filled with ice cubes. Garnish with mint sprigs if desired. Note: For a thicker drink, freeze pineapple juice in an ice cube tray. Blend these pineapple cubes with all other ingredients except mint. Omit regular ice cubes. Serve in a chilled glass.
