Once upon a time, there was a famous cat named Tom. He loved to play with a copper ball. One day, Tom met a dog named Max. Max said, "Hi Tom, can I play with your copper ball too?"
Tom said, "Yes, Max, let's split the time and play together!" They played and played all day long. They were very happy.
But then, something unexpected happened. The copper ball fell into a big hole! Tom and Max were sad. They tried to get the ball out of the hole, but it was too deep.
A little bird saw them and said, "Don't worry, I can help you!" The bird flew into the hole and brought the ball back to them. Tom and Max were so happy and thanked the bird.
From that day on, Tom, Max, and the little bird became best friends. They played together every day and had lots of fun.
