Once upon a time, there was a delicate cat named Luna. She loved to play in the backyard. One sunny day, she saw a big red ball there.
Luna said, "I want to play with the ball!" She ran to the ball and tried to push it. But the ball was very big, and Luna was very small. It did not move. Luna tried again and again, but the ball would not roll.
Then, Luna had an idea. She climbed a tree and jumped onto the ball. But, she did not know the ball was wet. Luna slipped and fell off the ball! She landed softly on the grass.
Just then, a kind dog named Max came to the backyard. He saw Luna and the big red ball. Max said, "Let's play together!" Max pushed the ball, and it rolled. Luna chased it and they both laughed. They played all day and became best friends.
