so it pooped out the food (or anon trash) and it felt refreshed after taking a dump but then it notices the smell of the smell (someone explain to me how do they smell again) and can't take it easy and probably asking anon to take it out. Need translation...
@Fart: Yukkuri senses vary a bit between authors, but it generally seems that they can sense things because they "believe" they should be able to. So, even though they crap out paste (which should be the same as their filling), they "believe" it smells bad through some mechanism.
Looking at various pictures, often yukkuri will willingly eat their own or other yukkuri's crap without noticing a "bad smell", so it isn't necessarily a "physical" phenomenon (not a real nose). So, the short answer is "magic + yukkuri ignorance".
Unnecessary crackpot theory about yukkuri smelling here. Yukkuris are born with basic knowledge like how to move, eat, talk, etcetera right? I'm guessing that includes the smell of everything. So, when a yukkuri senses something, the subconscious mind of the yukkuri will recognise it and send an impulse to the (bean paste) brain of the scent it would be giving off. But for yukkuri poo-poo, which is made of bean paste, the data will collide and the subconscience needs the yukkuri to sort it out. Hence, the yukkuri will smell what it thinks it smells. By default bean paste will smell like bean paste, but if the yukkuri is aware (or thinks) that it's poo-poo, the mind also processes it as such and recognise it as stinky.
Or it could work this way too. Yukkuris can smell alright but if it's poo-poo and the yukkuri knows it's poo-poo some sort of synesthesia (or whatever it's spelled) occurs and overides the actual smelling mechanism, leading to the brain thinking it smells.
Either way, I'm imagining that if I give perfectly normal bean paste to a yukkuri and call it shit, the yukkuri will think it smells bad.
Now that would be an interesting experiment Warui, i mean the whole getting normal bean paste and telling them it's yukkuri shit and see their reaction.
That reminds me. For some reason (shitheaded) yukkuris never trust a word from an anon and are like "what the fuck is stupid mister human saying" but they won't doubt the anon if they're told they ate their own shit and freak out, sometimes die.
I tend to think the stuff they excrete is ever-so-slightly different smelling than normal bean paste, in a way only yukkuri can really pick up on. the difference is faint, so dumber ones might not notice the difference after they forget it's there. or it's re-introduced some way(like in the other one where the parents moved their poop into a corner and the children didn't recognize it.)
Also, theorizing yukkuri are sensitive to smell because their whole body can sense smell which would possibly explain way they "see" so well in the dark of their nests.
