"Anti-yukkuritis
A disease that's triggered when a yukkuri receives a mental shock from a stress level more than it can handle.
For yukkuri, the act of vomiting its own filling is dangerous and could be fatal.
After pushing their filling back into their mouth, feed them with orange juice, and let them release their stress by praising and encouraging them while doing rub rub in an environment where they can feel easy. Also give them good quality sweet-sweets.
But if you do it too much, they could turn into scum, so be careful.
"No thanks. Orange juice and sweet-sweets should be enough."
I don't want to trouble myself that much for that little shit.
"Nwo... nwo mwore...
Goin' home... yugu... mwommy..."
It creeps while speaking nonsense.
"Where's your home? Besides, you don't have any mother."
I picked it up for further medical experiments.
