A long time ago there was a sparrow lived with her husband on a tree. She had built a nice nest and laid her eggs in the nest. One morning, a wild elephant with spring fever feeling came to the tree in search of branches for his food and in a rage broke the branch of the tree on which the nest was residing. Unfortunately all the sparrow eggs were lost though both parents were saved. The she-sparrow was deep in sorrow and crying a lot. Seeing her sorrow, the woodpecker bird, a friend of hers offered her consolation that she would think of a way of killing the elephant. Then she went to her friend the black fly, who is turn went to the counselor frog for advice. The frog then decided a scheme for killing the elephant.
He asked the black fly to buzz in the ears of the elephant, so that the elephant would be thrilled to listen to the music of the black fly and close its eyes. Then she asked the woodpecker to pluck his eyes. She herself would be on the edge of a pit and would croak misleading the elephant to think that it is a pond. The next day at noon the three carried out the plan and the elephant was killed when he fell flat into a pit after being blinded by the woodpecker when he closed his eyes in response to the black fly. So the revenge was taken with collective wit of all three animals.
Moral of the story: Intelligence wins over might.
