A family of yukkuri is crawling on the forest floor, carefully avoiding wet patches left by the just finished rain.
Reimu and Marisa are born at late spring and they grow to juvenile before the rain season begin. As soon as they left their parents' nest and meet each others, both decided to take it easy together. They're blessed with six baby yukkuri.
All the time, life has been nice to them. They live in a part of the forest that has a lot of food. In this place, many young yukkuri gathered and a young Patchouli declared the place as an easy place for them.
Other yukkuri, and even human that came to the forest to pick up vegetables had warned them, they better not stay there. Of course, they just think that the other yukkuri and human are just jealous of them.
If rain had fall, they would have understood. But luck is not with them, because until rainy season arrived, there has been no rain at all.
That's why, when finally the big rain falls, the whole clan as well as Reimu and Marisa's four children are all drowned.
With their food stock washed away and insects still in hiding, there's not much both yukkuri can do for their two surviving babies.
Baby yukkuri that lived an easy life with siblings and friends now have to live this hardship. The only thing their paste brain can think of is just to fill their stomach until they're satisfied.
But eating wet plants could cause diarrhea to baby yukkuri. Moreover, plants that grow early after the rain are bitter and hard, difficult for the babies to eat.
In this case, the only way left is to go and rob the farm.
Their clan has warned Reimu and Marisa to not go against human.
Yukkuri are simple and pleasure seeking creature. As long as they got what they want, they're generally a peaceful creature. But when they meet difficulties beyond the threshold of their paste brain, rather than starting again from the bottom, they'd rather bet everything on something risky but with quick return.
Things got worse if they have babies. Baby yukkuri doesn't know the meaning of self-restraint. Faced to this meaningless pressure, parent yukkuri would be more likely to choose the dangerous bet.
Marisa is confident she can chase away human. Same with her baby Maricha. In her heart, Reimu also think she can charm the human with her cuteness.
Yukkuri are easy to throw away their family, after all, they can make a big bet that might cost their life. Moreover, they are weak and that's about the only way they can try to stay alive.
Now, this couple is not really scum beyond salvage.
Marisa can hunt, and Reimu is a good wife. They're from the better group of yukkuri.
A regretable thing from them is their lack of understanding about danger, and their all too average intelect in that paste brain.
After getting out of the forest, they saw the farmland, with vegetables as far as they can see. The family is ready to go down and demand food to eat, until they smell something.
"Sweets sweets", that's what's in their mind. Yukkuri are sensitive to smell, after all, their whole skin are used to sense smell. Naturally, yukkuri will shake their body and pull in air into their mouth cavity to sense that smell better. But in city, stray yukkuri starts to mimic human or animal, smelling with their non-existant nose.
The sweets sweets plant looks very easy. Reimu go to look for Mister Dish, which are broad leaves used to serve their food. Not so far away she found them, as well as small insects yukkuri call the sweet bugs. These bugs tasted sweet and for wild yukkuri, they're the source of easyness. Smart yukkuri usually crush the bug and spread it like sauce to their food.
Reimu hold herself from eating the leaves, she still have to bring the dish to her family.
It's a very easy lunch after time of hardship. Maricha and Reimyu eat until they're full. After that, both lay down and sleep under the warm sunlight.
Marisa joined them and relaxed, while Reimu look at the babies curiously. She asked her children if they're really full. Normally, koyukkuri would need three to five times the amount they just ate to be satisfied.
Despite both saying they're full already, Reimu is still worried if they're not healthy. Both children's body only expand a little, while normally baby yukkuri would eat until their body bloated to eggplant shape.
The key to this is like in human or animal. By emotional cause, human could consume far more calories than they need. Yukkuri are no different. By eating, yukkuri will feel "happyness". Until they have enough of this easyness, they will keep on eating. This is why bad yukkuri will keep on eating and eating, because they just can't have enough.
Thinking of the stress they had, Reimu believed they should have ate more. Besides, there's a lot to eat here. Eat a lot, and let the poo poo out; it's a natural thing for baby yukkuri.
Marisa answered right though. This is an easy place, so even with just a little munch munch, they already feel easy.
Baby yukkuri can only do these. Play, eat, sleep.
In large family, the babies can get happyness by playing with their sibling. Thanks to this, they will consume less food, just enough to sustain their life.
As a result, the food consumed by family with two and six babies are not that different.
House is readily available. There are holes to the hill, enough for yukkuri family. The roof are made of stone, so it wont collapse and bury them alive like what happened to their children in the previous dirt house.
Probably the previous clan living here has give it away to Marisa's family.
Yes, this must be yu-heaven. Nobody is here because the heaven is just for the special yukkuri like them.
Yukkuri, especially Marisa, likes to think of themselves are special. It's said that this stems from their lack of confidence for being so frail. They also usually the father of the family, so acting strong made them feel easy.
Marisa's family decorate the house with soft sweets sweets grass. They have their dinner and then fell asleep after letting out poo poo to the gutter outside. It's a very easy place with lots of food and filled with easy smell.
When food is enough, yukkuri starts breeding. In return of the four babies they lost during the flood, Reimu is now bearing eight babies on the stalk growing from her forehead.
Maricha woke up one night when her parents are refreshing, and she rolls outside their nest to take an adventure. There, she found many bugs that she bring back home in the morning.
Reimu is mad because Maricha go out of the nest in the night. But Marisa in the other hand, feel proud because her baby can already hunt on her own.
Finally, the babies are born. All eight healthy babies landed on a sweets sweets grass cushion made especially for today. They all do greetings to each others and the two elder children are enthusiastic about their newborn sisters.
Reimu and KoReimu chewed the stalk and gave them to the newborn babies. After that, Marisa helped Reimu to prepare a large leaf for diaper.
After eating, the babies feel weird. They know something need to happen, but they don't know what. That's when Reimu and her daughter help by licking their anyaru, relaxing it.
Marisa only wait from the side. She told KoMarisa that one day she too will be a father and standing watch is also a duty. She encouraged the babies, telling them to stretch and finally, the runny brown paste that's baby yukkuri's poo poo flowed out.
The happyness is broken in an instant when the babies cried from the smell. One baby vomitted paste and die, while another two died in chain reaction from the death stench.
Marisa quickly told her two elder daughters to throw the diaper out and she herself carry the dead babies outside. Reimu cleaned the rest of the poo poo.
To calm down the babies, they gave them food, the very easy sweets sweets. Unfortunately, the babies can't eat it, claiming unhappyness and gross, even poisonous.
The parents and KoMarisa have to offer their stockpile of food to the babies to calm them down.
These babies eat a lot until they turned to eggplant shape. Reimu remembered again, back then, babies sure eat a lot. All this time, with easy smell around them, the family doesn't need to eat much to achieve easyness. They almost forgot how much yukkuri can eat.
When about to do poo poo again, a baby Marisa recalled the trauma of poo poo = death. She vomitted her paste and died.
Reimu and Marisa acts fast and cleaned the poo poo quickly this time. If they clean the poo poo quick, the baby will survive.
That night, the family finally calmed down and went to sleep.
Like human and animals, yukkuri also have incontinence. One of the baby can't hold back and leaked poo poo during sleep. Just a little, but yukkuri's skin are their smelling organ. When morning came, all four babies are dead.
This place is not natural. It's built by a yukkuri breeder, helped by Noukarin, to create new product.
His project is to make use of yukkuri in farm. How is it possible ? Yukkuri think that vegetables just grow on their own, they can't be useful.
It's well known that pet yukkuri likes to be in toilet. Cases of stray hiding in public toilet are not uncommon either. Apparently, yukkuri think of mint as sweets sweets.
That's the secret of this plot. The sweets sweets vegetable are mint. With the smell, they can make the yukkuri consume less to achieve easyness.
The dish leave are beefsteak plant. Yukkuri help pruning the plant so it doesn't grow too much and became hard. Moreover, the yukkuri mainly eat the leaves with plant lice, which is a good thing for farmer because those bugs are pest. A win-win situation for both farmer and yukkuri.
Cutworms' larvae hide in the grown during the day and came out at night to eat the plants. But they can easily be lured with sugar from yukkuri's poo poo, which runs in the ditch. At night, they're also hunted down by the yukkuri for food.
Unfortunately, the experiment is only successful with mint and beefsteak plant that's hardy and grow quickly. That's not yet enough for commercial scale.
In another place, the breeder also tried using Aquatic Marisa to control the population of water hyachinth and water cabbage.
At first, they don't want to eat water cabbage, but without given any other food, those yukkuri starts eating the weeds even if they cried doing it.
In the other hand, mini Aquatic Marisa works well with water hyacinth. He had thought of making it a product. Mini aquatic Marisa can eat the fast growing weed, while their poo poo will become nutrition for the plants.
But this man's main project is to use yukkuri for agriculture. If he can find a way to use yukkuri to clean up parasites in commercial scale, he will surely reap profit.
The key to get money in this business is to innovate and develop your product as soon as possible. You can't go straight against the giant Factories because there's no way you can match their scale. The only way is to find an opening where they still hasn't set their feet yet.
Even the Factory still hasn't managed to control yukkuri to eat only the weeds and parasites. They could treat the yukkuri like slave, but the next generation will lose that trainin and induced another cost.
Smell seems to work well. Yukkuri's appetite is controlled by their need for easyness. With the mint frangrance, yukkuri appetite can be kept under control and even if there's idiot, risk of scum can also be reduced.
About the reason why the baby yukkuri dies, that's because of the stalk pregnancy. This family decided to get a lot of babies in one go, so they choose the stalk pregnancy which is not perfect.
Its said that if a yukkuri love her children, she will have mammalian pregnancy. In the other hand, family that need both parents moving actively to hunt will lay egg. House yukkuri lay egg for this reason.
So why choose stalk pregnancy ? It's a selfish reason, really. Yukkuri feel easy from seeing their baby grow. they also feel easy from knowing they're taking care of their babies.
The positive side of stalk pregnancy is that, by being exposed to the environment, they adapt better to the environment. Although, it also means they adapt too well, so most babies born from stalk in winter wouldn't survive summer.
In this case, living in house filled with smell of mint made the babies lost their resistance towards bad smell. They doesn't even know how bean paste smell and this resulted in babies that died from just the smell of poo poo.
If Reimu and Marisa choose to have mammalian pregnancy, this tragedy wouldn't happen.
They choose to get back a lot of babies at once though, the choice that cost them up to 50 baby yu before the breeder finally decided to wash away this family.
With just a switch, water from the reservoir can be directed through the nest holes, washing out all the yukkuri and use them as fertilizers.
Rainy season is close, and a yukkuri clan surviving flood will soon came to rob the farm. This easy place will be a trap to stop them again.
