@Stalkerman I think it's technically just parasitic, with being a full parasite being them doing something similar their whole life cycle, or most of it.
Side note: I only saw this message at a glance at first and read pirates, so that was an interesting chain of thought to go down for a moment.
Wait... If a tomato grows a tomato+ sized little devil... What would a pumpkin do? Or a humanoid?
Would it become huge? But if it becomes huge, would it become more featured or will it stay doll-shaped?
Would the body change to be more like girls or guys?
Million culture question: Would boobs grow?
I honestly had the thought on the panel where she told the little devil that she would make an adult out of him. Did not actually expect her to actually make a baby
