she has always had breast expansion. I think there is a cap. I do not know how many will reach it.
The apple spawn rate was actually increased. It used to be 2-6 now it is 2-8.
She can carry 3 but for her to chase you after eating 2, you have to have no items on you and she has to have no items in her.
It is that item you saw that one day before you got caught.
