Two little Marisa is stuffed inside a egg pack. Their feet is burned with number 1 and 2 sign. Both are still asleep and most likely they're packed as soon as they're born as compost yukkuri.
Although a little troublesome, as long as you breed them according to the manual, they will last long in their job. The little baby yukkuri can be trained quickly into compost yukkuri, but they're also popular among the yukkuri lovers.
The burn mark on their feet served two purposes. First is of course to make it easier to differ between both of them. The other purpose is to limit their movements.
By the way, although Marisa types are known to be arrogant and delusional, these compost types are breeded with even stronger traits.
First, put them in a container and leave them under the sun for a while. Most peoples would use sound-proof transparent box to keep their noisy voice from disturbing.
The heat will wake them up from their suspended state and they will awake from the sleep normally. Those who are not so patient will either stab them with toothpick or hit them. The man tried stabbing number 2.
Number 2 awakened by the pain while number 1 is awakened by the noise. Angered because her glorious birth is disturbed, number 1 puffed to the crying and peeing number 2.
The package included food for three days. These food are black, dry, hard and smelly, all made to train the yukkuri for compost processing.
At first, the two yukkuri screamed and demanded their slave human to clean it up, but he just close the lid and leave them in a room.
These two yukkuri are very active, so they will soon lost to their hunger and eat the food.
Both tried eating the food, but they quickly spit it out because of the bitter taste. After seeing the human doesn't care about them, they tried again. Their body excreted a lot of saliva to make the food taste better, but the dry food just absorb the moisture and became even bigger.
Even so, they forced themself to eat while crying about their sad life, one even compared herself to Cinderella.
Apparently, the Factory played CD about Cinderella everyday to the seedbed, planting an illusion that one day, a sorcerer will came and bring them a happy life. Such idea is also inherited to their children, the products.
It's yukkuri's nature to expect help from others. With this idea, compost yukkuri are psychologically supported by the delusion that if they survive, one day a miracle will happen. This way compost yukkuri can live to the end of their lifespan despite their environment.
After eating, both starts making poo poo like shit converter engine they are and then screamed from having their poo poo near them. Well, even the ultra-narcisstic creature like yukkuri won't like their own shit.
For breeding, usually human will prepare something to clean the shit. The yukkuri will think that the poo poo will just disappear on its own, just like vegetables will grow on its own.
Pet yukkuri in the other hand is trained to do it in specified place. Poo poo is something uneasy and those who handle it are looked down by yukkuri. This is why there's many case of yukkuri turning into scum and call their owner as slave.
Such yukkuri need to be trained to clean their own mess and to be grateful to their owner.
As for compost yukkuri, there's no need to clean it. Yukkuri will get noisy, but those paste pose no harm to human. In days without any trash, the yukkuri can also eat their own shit to survive.
Don't think of making perpetual machine with this though. Yukkuri also convert the food into energy and for growth, so in the end they will stop shitting and starve to death.
After three days, despite still complaining about the taste, Marisa 1 is already used to eating the bitter food. Actually, the food also contain anti decomposing agents that's good for the yukkuri's health.
Marisa 2 is not in good shape though. She's broken mentally and starts talking incoherently while eating poo poo.
The man then picked up Marisa 2 and crush it in front of Marisa 1, then leave them there for another half a day until Marisa 1 is so hungry she begs for even the Mister Bitter Smelly food.
After there's no more poo poo left, Marisa is still hungry. She then forced herself to eat the corpse of Marisa 2 while crying.
Actually, the compost yukkuri is Marisa 1. Marisa 2 is just a regular yukkuri. Their body is weaker against mold and without mental support from illusion of being a cinderella, they won't survive. Even if they managed to eat the trash, usually they will be broken in half year at longest.
With this, the compost yukkuri will experience the vanity and fragility of yukkuri. They will also be trained to eat poo poo and other yukkuri's corpse. Since yukkuri basically only learn from what they experienced, this is better than trying to teach them anything.
After finishing this, he bring the box to his yard. There is his compost box. Inside is a big Marisa with childlike tongue, probably because of the environment or because there's nobody to talk to. But light of hope never disappear from its eyes.
He has used this compost yukkuri for a year and recently the processing power has dropped, so he want to change to a new yukkuri.
The man tore that Marisa's hat and destroy its tongue. He then stuffed the leftover trashes into that Marisa's mouth and put in the new compost yukkuri inside.
He destroyed the tongue so the previous Marisa won't talk to the new Marisa.
With this, new generation of compost yukkuri is installed, living its "cinderella" life until Death came.
