UPDATE! Found the "recipe" for Alaskan Water and Hawaiian Water drinks! With video!

I posted about this a couple weeks ago, and someone from BookFace sent me this video.

The exact measurements aren't included, but, beyond the Blue Curacao and Midori Melon, the creamy/fruity base is identical, as is the use of ube/purple sweet potato juice.

Hoping my next Alchemy/Amari bartender has this off-menu forbidden knowledge!
