What are all the places I can find the rare milk fruits?
I'm unsure, but I know one can be found in the desert oasis after solving the gem puzzle, one in the druid town in the fertility forest, and one at the end of the cowgirl milk dungeon, mabey one more somewhere after the witches academy but I cannot say for sure, use one of them at the cowgirl farm to unlock the ability to buy them from the shop in the area.
