This is a yukkuri ant aquarium craft.
The usual ant aquarium kit is filled with gel edible by the ants. Then as the ants eat and dig their nest, we can see them through the transparent gel.
Yukkuri version is similar. First, get a yukkuri and burn its feet. After that, inject them with a special liquid. This will make their paste turns semi-transparent. Then peel off all the skin except its face. For beginner, it's highly recommended to use sedative because if they struggle, the paste could crumble and they would die.
After peeling, just put the yukkuri in an aquarium. It would fell asleep after wearing itself off from the pain. Ants come after this.
The ants will starts going to the yukkuri and dig hole to its face to eat their innards. The injected solution made them more inviting to the ants.
Yukkuri will die if they lose critical amount of paste or have their paste core damaged. Of course, the ant aquarium yukkuri wont die easily. As long as they're alive, yukkuri have the magical property of keeping itself from rotting.
Probably because of the alien pain, they don't simply vomitted their paste. Ants also wont be able to eat as much as the critical amount of paste to kill yukkuri.
For unknown reason, ants also ignore paste core. There are theories like the ants know to leave that part alone or that the paste core release components the ants don't like.
To feed yukkuri, it's recommended to just put food out of the yukkuri's reach, such as cake. The ants will came out and bring the food into the yukkuri, forcing it through all holes they've made. Then amazingly, the ants throw the food into yukkuri's throat, their digestive organ.
They're living in food, so there's actually no need to take the food outside. But this is to keep their nest alive and replenish the paste.
The man is asked for help by his friend to clean a yukkuri ant aquarium. As the boom is over, he neglected his yukkuri and the yukkuri has rotten. Of course, the ants are all dead too.
Anon is asked because his friend is too disgusted to touch. Well, he would have to put a price on this service.
While cleaning, he felt something moving inside the crumbled paste. He asked what his friend is feeding before it dies.
A raper Alice who attacked the neighbour's pet. He hit the Alice and feed the remains to the yukkuri. Apparently, the ants accidentally throw some sperm custard and missed the digestive organ, going straight to the reproductive organ.
The little Alice born in rotten paste is black and inside her is a colony of ants.
