Once, a lion was resting under a tree in a jungle. A mouse, who lived nearby jumped over the lion. The lion was very angry. He caught the mouse under his paw and wanted to kill him. The mouse requested the lion to spare his life and promised that one day would be of some use to him.
One day, the lion was caught in hunters net. He tried his best to set himself free but in vain. He started roaring. The mouse heard his roar. He started cutting the ropes of the net with his sharp teeth. The lion was set free. He thanked the mouse for his help.
