There's a new "mythical creature" Frappuccino on the Starbucks secret menu.
It's called a Mermaid Frappuccino and it's made with vanilla, frozen blueberries, and a green coconut matcha sauce. It's not an official item so be ready for the barista to not know what the hell you're asking for when you order it.
It honestly doesn't sound too bad. Like it might not have as much sugar as the Unicorn Frap. And it's got caffeine with the matcha so I might have to taste test this one, too.
