Unicorn Frappuccino on menu at Starbucks through Sunday

Starbucks is adding a magical drink to their menu starting Wednesday. The Unicorn Frappuccino changes flavors from sweet and fruity to tangy and tart - like the opposite of Sour Patch Kids. The drink has a dusting of pink powder blended into a crème Frappuccino with mango syrup and a sour blue powder topping.
