The Unicorn frappucino was weird. It was good.. tasted like mango and cream but then they laced it was some super sour syrup and put some super sour bits on top of the whipped cream which honestly ruined the whole thing. Because they weren't delightfully sour like a sour tart or anything like that, no they were bitter and horrendous and almost painfully sour. It was gross. And because of that I would not get one again and have not tried any of their fancy promotion frapps since. I had no idea there was a Lucifer one though, that's hilarious. I might try that one if I ever see it. XD
