One Piece Devil Fruit User Suggestion
During the Fishman Island saga, it is shown that devil fruit users can survive underwater if they use a bubbly coral to produce an air bubble around themselves. So why wouldn't they all carry these if they fall in the water instead of drowning? Franky should be able to engineer a device that would automatically depress the tip of the coral at a certain depth using a mechanical depth gauge. This way it wouldn't be triggered if it just got wet by a wave/rain or if it was somewhere they could just stand up. Finally, the coral or breath dial could also inflate a tube so they could still limitedly function at the surface when the air bubble pops. Even though it creates suspense when they need to be saved from the water, the coral could run out of air or get popped instead.

Funimation doesn't make the anime. Nor do they control the story, they Just dub it.
