Yeah like others have said, Luffy has been shown to remain rubber even with his body submerged in water. This was sort of explained with the idea that his DF permanently altered his body, and the sea water while it makes him weak and unable to control his body apparently doesn't remove the actual property of his body.

Actually, talking about this makes me think about Moriah's ability. Yes I know onion head's ability is full of plotholes, but the idea that splashing sea water purifies the zombies makes me wonder why wouldn't splashing sea water on a toy turn it back? Moriah didn't actively 'maintain' his zombies either. Sure he could control them if he wanted, but the hundreds of zombies were pretty much doing their own stuff.

In any case, if we consider Sugar's toys to be as intrinsic as abilities that alter a person's body, I suppose there would be no issues with Sugar sleeping.

Now I do have yet another thought that just popped up though. Luffy being in seawater does not alter his rubber form. Similarly, Brook doesn't die when he falls in the sea. He becomes weak and immobile like any other DF users despite how the entire reason he's alive is that he is sustained by his DF powers. Now as mentioned by Awai, BB negated Luffy's rubber body entirely with his powers 'sucking' the DF out of him. What would happen then if BB used that ability on Brook? Will Brook *GASP* actually die? Or perhaps his soul will just be separated once again and float out of his body, and once BB stops using his power, Brook can fly back in and repossess the body?
