Long, long ago, there lived four cows in a jungle. They were fast friends. They always grazed together and saved each other when some wild animal attacked them. This was the reason why even tigers, and lions couldn't gather the courage to kill them and eat them.

A lion had, indeed, an eye upon these cows. But he could never find the right opportunity to make them his prey.

One day, the cows fell out. Each one grazed separately her own way. This was the right opportunity for the lion to attack them. So, the lion hid himself behind the bushes and when a lonely cow would come closer to the bushes, he would pounce upon her and kill her for his meals. In this way, all the four cows were killed one by one by the lion.
