A mouse left its home and encountered a large lion who wanted to eat it. The mouse pleaded for its life, saying it may be able to help the lion someday. Though skeptical, the lion spared the mouse. Later, the lion got trapped in a net and cried for help. The mouse heard the cries and found the trapped lion. Though small, the mouse began gnawing at the rope and freed the lion. From then on, they were friends forever.
