One Piece Prompt 41
The straw hats rescue you from your island where you had been trapped in a colosseum when you are post battle in your skinny form. You stay in your skinny form for a week before Luffy complains about how lethargic you are and tells you to eat more. You are worried because of how much you eat, but Zoro, noticing your nerves, challenges you to an eating competition since you were docking soon to restock anyway. When you keep eating, even after Luffy, they all stare in amazement. That is until they notice how quickly the fat is returning to your body. You end up in your half-gum form, a bit more plus sized then normal so they ask about it. You admit you ate a devil fruit that lets you turn calories into energy, so the fatter you are the stronger you are. Sanji makes it his personal mission to fatten you up as often as possible.
