I tried to find a thread like this [no luck].

 

What if Sora has to go to the bathroom also all the characters.What about sleeping and resting like the battle with Master Xehanort.What about taking a shower and eating (i guess maybe a potion).What about sleeping(too bad Sora donald and Goofy only got it).Last of all,what about washing their clothes?

i dont know i mean in the manga they ate and washed up but in the game i guess they didnt want the gamer to see them wash their hands and eat in the middle of a random boss battle.

i guess it is kinda like gears of war, they have books for it, the game covers all the fighting but the books cover the inner depth that the game doesnt show, (my brother bought the books for like $30 bucks, i never read them though)

Well I believe they can sleep in the Gummi Ship, while someone else drives. The potions count as food, and for washing clothes....who knows?

the gummi ship seems so small though o.o.(But not in the manga)

LOL, they do a one year adventure in seemingly one day. That's weird. The bathroom part...I never really knew about that. I was also thinking where do they park the Gummi Ships? I saw the part in Disney Castle where they had a hanger, but in the rest of the worlds, they are beamed down to the face of it.

that is weird a one day journey i wonder why sora isnt so sleepy in game either

LOL yeah indeed It's liek they never get a break They go on and on and on and what should take weeks , it's like done in a day Though , in kh2 , Sora's clothes are magical so maybe they clean themselves x) . Though yeah I rly wanna know when they go to bathroom I can understand food and stuff ... more or less , but bathroom is something that can't be avoided And rly , also in kh2 , Sora has in his inv that seasalt ice cream , does it never melt ? o-o

I dunno. Somehow they magically are never sleepy, never need to eat, and clothes amazingly change when there's no way they could've from game to game.
