How come Zoro hasn't had any mouth infections yet?
SET FAIL FOR ONE PIECE
Oh, I get it, because he holds a sword in his mouth.
they're miraculously healed after a very short period of time so they don't really get any mention
How come in one piece they havent fought against any ninjas? i mean they are the sworn enemies of pirates
Because the natural enemy of a ninja is a shark. You should know this by now.
Because bandages fix everything.
Hasn't Chopper taught you anything?
