The new espresso drink, sprinkled with pink and blue "fairy powder", clocks in at 410 calories and 59 grams of sugar in the 16-ounce "grande" size.
Another barista shared an image of 56 Unicorn Frappuccinos that constituted one order, and others gave thanks to customers with simple orders like a black coffee.
Starbucks said in a statement to Boston.com that the company is listening to feedback from both customers and baristas about the drink. By swirling the drink, yu can "reveal a color-changing spectacle of purple and pink".
One Twitter user wrote: "Really hope the Unicorn Frappuccino comes to the United Kingdom because it looks like all of my dreams coming true in a coffee cup". On Reddit, one user recounts their particularly jarring experience with the Unicorn Frappuccino. "I have never been so stressed out in my entire life".
Burson later said he didn't think his rant would get this much publicity and he didn't intend to "downgrade" the drink.
According to reports from TMZ, Burson is NOT getting fired over the video, in which he said: "For the love of God and everything that is good, don't get the Unicorn Frappachino".More news: Bill Murray to release debut album, New Worlds, this August

Braden Burson: 'I have unicorn crap all in my hair and on my nose'.
The Unicorn Frappuccino itself won't be returning, however.
The Unicorn Frappuccino will end its run on Sunday, April 23, 2017. "The world is complicated, and we know that now more than ever it takes more to make you smile".
Personally, I always pictured unicorn blood as the silver Elixir of Life liquid described in "Harry Potter", but I guess this Lisa Frank rendition makes sense, too.
The drink has also caused baristas to freak out, too.
