This koyukkuri might be the same one in post #2724 that stole the medicine for its sister. And would therefore be responsible for the reimu koyukkuri not being there to starve when they ate a week's worth of food in a day.
I checked the Chinese site and the new thread doesn't begin with those images which suggests we're missing a lot and there were no consequences of child marisa eating that pill, no death or punishment, but the child reimu died.
I remember reading someone's theory that yukkuri don't defecate in the wild because they don't get enough food. However, humans feed the yukkuris too much and thus there is a lot of waste that must come out. This strikes me as odd because why would nature give yukkuris an anus when they don't naturally poop but then again yukkuris aren't bound by natural laws or common sense so I like the theory. Also explains why they are so surprised by the poop here.
In that case, what if the yukkuris have lived in captivity for a long time and the human has always disposed of the poop or they had a special "toilet bowl." No, with the bigger tank with lots of dirt, the mother marisa has made them a home and there's no one to clean it up.
L to R 1) I'm doing poo poo! yuyu-!? 2) Reimu: aaaahhh! What are you doing!! Reimu: ma-marisa, don't! To do poo-poo inside the house... do it outside please! KoMarisa: But it's cold outside! Mommie and everyone ran away from it Marisa: Y...You're going to do poo-poo in this cramped space... 3) YHU-? It stinks! Yuyu-! It's a new record! See! Stinks!
IMO it is also a part of the built-in knowledge implanted in their bean paste when they are born, just like their innate fear of the Factory. Good thing they are stupid, have short memories (and probably can't smell very well) that you can "repackage" their shit and present it as food for the yukkuris.
Well I don't mean in that way; I sometimes like it when they remember and are forced to begrudgingly it by their tormentor. I meant in the way that first-time parents are disgusted when their child first poops/throws up but then they become used to it. Here the parent yukkuris are acting like it's their first time seeing it. But the new house/captivity/don't-poop-that-much-in-the-wild theories previously stated explain it.
I don't like it when artists adhere to a set canon all the time. That makes thing predictable and boring; artists should have liberty with the facts, like how much they can remember.
I think they wasn't surprised by a poop. They're surprised by their kid's thoughtless action(pooping inside a hole they have to live in to avoid a cold weather)
Reimu did say if child-marisa have to poop she should do it outside (above the hole)
>>thoughtless action >>yukkuri One should strive to eliminate redundancy in one's writing.
YU!?See! Stinks!It stinks! Y...You're going to do poo-poo in this cramped space... But it's cold outside! Mommie and everyone ran away from it ma-marisa, don't! To do poo-poo inside the house... do it outside please! aaaahhh! What are you doing!! Yuyu-! It's a new record! yuyu-!? I'm doing poo poo!
