Helena, Lumiose City’s local Hex Maniac, is selling bottles of her special Moomoo Milk for P500 a bottle. At that price it’s quite a steal so buy a lot. Unfortunately she seems to have ran out of her delicious drink before you can get any. Though it will take a little bit of time to collect, she can get you a bottle, but it’ll be a lot faster if you help her. That all depends on if you can keep how she acquires such a delicious beverage a secret. (Some reason the Ai couldn't make her look anything like in legends Z-A so gallery will be a little bare. Let me know if anyone finds a way so I can add more images.)
