Starbucks fans are already obsessed with the chain's latest — and perhaps strangest — creation: the Unicorn Frappuccino.

But what is this mysterious, color-changing beverage?

According to the coffee giant, it's a "flavor and color-changing creation" made with a dusting of pink powder blended into a mango creme Frappuccino and layered with a sour powder topping. When you stir the drink, the color transforms from purple to pink, and the flavor goes from sweet and fruity to tangy and tart.

The drink will be available for five days starting Wednesday.

Of course, more questions remain.

What does the drink actually look like?

The flavor and color changing Unicorn Frappuccino from Starbucks. Doesn't matter that it isn't coffee-based, I'm sure there's enough sugar in it to get me through the morning. #UnicornFrappuccino #Starbucks #NotCoffee #Sugar #Unicorn A post shared by Alex McNeilly (@xandarbarbarian) on Apr 18, 2017 at 7:32am PDT Apr 18, 2017 at 7:32am PDT



Starbucks has released an official image, but when it comes to mass-produced Starbucks drinks, the reality often diverges from the ideal, Instagram-ready image.

Fortunately, a few Starbucks sleuths have prematurely posted pictures on Instagram.

Judging from early photos, the change might not be as stark as Starbucks promises — but the drink certainly boasts some bold colors.

This isn't the first unicorn coffee drink on the market.

The End, a Brooklyn cafe that opened in late 2016, is known for its multicolored, creative lattés — including the Unicorn Latte, made with ginger, lemon, coconut milk, honey, and E3Live blue-green algae.

A HUGE thank you to everyone that came out to support. Last night had so much sparkle in both a metaphorical and literal sense (still trying to get the glitter off of everything 😂). The Pegasus is still on the menu. Come by and try one for yourself 😉🦄🤗 📸: @laurenmagenta. A post shared by DRINK NYC (@drinkaeo) on Mar 24, 2017 at 9:33am PDT Mar 24, 2017 at 9:33am PDT



Basically, all you need to know is that unicorn lattes are trendy and super colorful, and Starbucks didn't want to be left out.

How unhealthy is this drink going to be?

Adding a beverage that looks like a blenderized doughnut to the menu means many people will question the drink's nutritional value.

A Starbucks representative told Business Insider that a tall Unicorn Frappuccino made with whole milk and whipped cream would have 280 calories and 39 grams of sugar. Take away the whipped cream and make the Frappuccino with almond milk, and a tall has 170 calories and 34 grams of sugar.

The Food and Drug Administration recommends limiting your daily sugar consumption to 50 grams — so it's probably a good idea to stick with the tall.
