According to a bartender at Red Lobster, they use a mix called "mango passion" ( just a tropical blend of mango and berries) with a shot of Captain Morgan and blend with ice. A strawberry syrup or grenadine is plashed around the inside of the glass. Pour in ice mix then top with Myers Dark Rum. Garnish with an orange slice + cherry.
