Once there were a lion and a mouse, who lived in a jungle. The lion was sleeping and the mouse came into his place. The mouse climbed on his nose and woke him up!

The lion captured the mouse in his hands and he wanted the mouse to be his lunch. Then, he let the mouse escape because he was too tiny to eat him and his belly would be still hungry. Some time after, hunters set a trap and the lion was going for a walk. Suddenly, the trap caught him. He called for help and the mouse showed up to help him. It nibbled the net. Then, the lion was saved.

The lion thanked the mouse. Finally, the mouse and the lion became best friends forever. From this story we learn that one good turn deserves another. This means it's good to help someone who has helped you.
