The Spirit of Creation had finished the work and came to see what had been done. There were mountains, rivers, rice fields and beautiful valleys. The trees danced in the wind and beautiful flowers all over.
The Spirit of Creation was very happy.
The Evil One suddenly appeared before the Spirit of Creation. “You do not have to be so happy.” The Evil One sneered. “There are many things that you have created that are neither useful nor beautiful. This thistle is ugly. The bramble is not useful either.” The Evil One studied the Spirit of Creation. “If I had created things, I would have done it much better.”
The Spirit of Creation became very angry on hearing this. From the anger of the Spirit of Creation, a rat was created.
The rat looked huge and fierce.
As soon as the rat had been created, the rat jumped into the mouth of the Evil One and bit off the tongue of the Evil One.
The Evil One screamed in pain. But then the Evil One realized it. If the rats are here, they can torment all of earth.
So the Evil One increased the number of rats until the rats overran the Land of Ainu.
After this the people were very unhappy. The rats carried off their grains and gnawed the huts that people made and also frightened little children.
So the people went to the Spirit of Creation. “Please take these pests away.”
