Unicorns aren't real, but Unicorn Frappuccinos are thanks to the good folks at Starbucks! 

The odd concoction isn't on a secret menu or only available out of the country, it is actually a real thing you can order at your hometown Starbucks. 

It's made with pink powder that's blended into a crème Frapp with mango syrup, it's layered with a sour blue powder topping.

That's just the tip of the unicorn horn, though... The Unicorn Frappuccino starts as a purple beverage with swirls of blue and a fruity and sweet taste, but once you stir it, it turns pink, and the flavor evolves to tangy and tart.

The magic drink will only be available from April 19 to April 23 while supplies last.
