Once upon a time, there was a big lion. The lion was troubled because he lost his metal toy. He looked for it everywhere. He was very sad.
One day, the lion heard a noise. It was a little mouse. The mouse found the metal toy. The lion was very happy. He said "thank you" to the mouse.
The lion and the mouse played with the metal toy. The lion roared with joy. They became good friends. They played together every day. And they were never troubled again.
