* Jimushi Juubei smokes a pipe. No one knows how he stuffs and lights it, given that he has no arms...
** Same way he travels while not crawling- he has subordinates doing it for him.
** No, he does it himself with his tongue. This is possible, in a movie I think called Misfits, (it was about a bunch of real life freaks), a man without limbs is able to set up his pipe himself.
** Considering that he managed to kill a man, steal a valuable scroll from a bunch of expert ninjas and outrun (well, outcrawl) them, I guess that he can light a pipe just fine.
* Not sure, but why Okoi did not retain her large lips in the anime?
** It's difficult to animate.
