When we were there last week they did not have blue milk at the milk stand outside either... They only had green and the Toydaria Swirl which is green milk with some other stuff (I enjoyed it, except for the jellies in the bottom but I just didn't eat those). I wonder if there's some kind of supplier or ingredient issue for the blue milk (I know the one in Oga's is chilled/slushie style but I think it's still the same base item)?
ETA: I see blue is available to mobile order today so IDK
I was there last Wednesday and they had both flavors at the milk stand.
The "Blue Bantha" in Oga's is totally different than the milk stand, BTW.
