Mister's garden is not so big, but inside he has two circle red and blue made from jumping ropes. The two circles is separated at 5 metres.
20 baby yukkuri bring stone from one circle to the other without rest.
After five stones, they're given water. After 20 stones, they're given 30 minutes rest and food pellets. After they moved all the stones, they will have to move it back.
One day, a Chen protested about why they have to do such meaningless job. They want to take it easy.
To explain, Mister gathered all of them.
"Do you want to take it easy ?"
"Want to take it easy!"
"Alice, why do you want to take it easy ?"
"...yu? Because taking it easy is easy."
"What's so good of being easy ?"
"...yu, yuuu ? To take it easy is city sect and happy...?"
"So if you're easy, then you're happy ? But why are you happy if you take it easy ? What's the reason ?"
This hit the limit of the baby yukkuri's logic, they can't answer.
"It's the same. Why do you work ? There's no reason, you just do."
The babies are still not sure they understand. Mister also understand that he wouldn't be able to make out better words, he also hit his limit on talking skill. So he choose a physical example.
First, he called a stray Marisa who happens to pass by. This Marisa looks terrible even for a stray, totally uneasy. Marisa is already afraid of Mister, but he told Marisa he doesn't mean to do any harm.
Marisa first wanted to ask to be taken as pet, but she know that's impossible.
Instead, Mister offered, if Marisa bow down and beg, he will give her food. Marisa quickly do, and Mister throw down a manju, step on it and mix the manju with dirts. Even so, Marisa still eat it silently.
Mister then explained, that's the yukkuri who never learned to work hard. They will not get anything without hard work.
Three months later, the babies keep on moving stones and they've grown into adults. They never complained anymore.
Seeing them growing up, he then moved them all to the forest when they're sleeping. He also left the two rope circles and stone.
Right now, they must be moving stone everyday, hoping someone will give them food for it.
