The Blue and Green Milks that you can purchase at the Milk Stand at Star Wars: Galaxy’s Edge are both frozen an have unique flavors. A lot of people have discovered that they like them mixed. If that is how you want to try them, you’ll have to order one of each and ask for an extra cup. At this time, the Villagers will not mix them for you. Personally, I still prefer the blue alone, but mixed was good too.
