Yall, do people not use the bathroom in this universe

naw, like, where's the bathroom? Is the bathroom not an area, does foam block the bathroom? If so, where's the piss and shit bucket. Does Anya get a separate bucket? Does Curly poop, I know he hasn't eaten but after he ate his leg he must have to take a shit. Does Curly even pee? How? Does anyone take him to the bathroom? Does their food even have nutrients they cant digest? Do they have toilet paper? What do they use as toilet paper? If one of the members got flatulence or food poisoning, do they all have to live with that until it recovers or the ride just ends? So many unanswered questions
