The fruit is actually OP if you think about it. Ive been reading the Wikia, and apparently it allows them to swim through any solid object. Not only that but it makes the object turn into a liquid like state whilst retaining the properties. This nibba would be able to swim through diamond and shit. His DF would go through any durability like Law's fruit. If he can swim through humans as well.....(since that should logically happen to). Then Sanji would be fucking hax.
I feel like the only reason you do not like the fruit is because it belongs to a fodder character.
