Unicorns have been very "in" in beauty, clothes, food and tech. Starbucks is trend hopping with their limited-time-only unicorn frappuccino. The blended creme drink is made with pink powder, mango syrup, sour blue drizzle and vanilla whipped cream. The drink starts off purple, sweet and fruity but stir and it's pink, tangy and tart. The beverage is available from Wednesday, April 19, through Sunday, April 23, while supplies last.
