Btw, about Mama...
Its the comum sense to think she canibalized Carmel, and thats how she took the fruit
I do agree its one of the most acceptable thinks but, lets try the other, to think it was not:
The fruit could just had appeared next to her, and she ate..
Or this have something to do with Souls Fruit Powers and some kind of Carmel Abilities
Why I say that:
The thing is that, eat someone, wouldn't it be the same as Kill someone ?
The user would be killed in the process..
Than, the system would work like: The User got killed - The fruit migrates to the next
The fact that you eat the person, would only be plausible if the "soul of the fruit" just migrates to the canibal person body by acquiring the DNA, not the stomach..
Once you eat a devil fruit, the DNA from the devil fruit will form a new DNA with the user, like stated in the story
The fruit alone would be precessed as another food, so the stomach makes no sense, but the DNA
And during WCI and Wano we got to see more about the Linlin personality, so I don't trust 100% it was acquired by canibalizing Carmel
