Starbucks calls shifting-color drink a "Unicorn Frappuccino"

Advising drinkers to give the beverage a stir for a magical transformation, Starbucks revealed, "Its color changes to pink, and the flavor evolves to tangy and tart".

If you want to take a sip of this whimsical new item, you better hurry: The Unicorn Frappucino will only be available from April 19 to 23.

Before Starbucks confirmed the release of the drink, employees at stores in Washington, Iowa and California, among other locations, posted images of the drinks on social media.

What is a Unicorn Frappuccino?

But like the mystical creature, the drink is quite elusive - and will only be available in stores in the United States, Canada, and Mexico through the end of the weekend.

It starts out purple with a blue streak through it, but changes to pink when mixed up. "It is finished with vanilla whipped cream and a sprinkle of sweet pink and sour blue powder topping", the company said of the drink.

On social media, many seemed onboard with the new drink.

More than a drink, Starbucks is branding the Unicorn Frappucino as an experience.

So far, people are pretty hyped about Starbucks's new concoction.

The purple comes from the sweet powder that is added to a crème Frappuccino. After baristas reportedly tested out the recipe for about a week, the highly anticipated drink is getting an official spot on the menu.
