Once upon a time, there was a big cat named Tom. Tom loved to joke and play with his friends. One day, Tom found a ball of yarn. It was red and soft. He was very happy.
Tom played with the yarn all day. He rolled it and jumped on it. He made a big mess. His friends came to see what he was doing. They saw the yarn and wanted to play too. They all laughed and joked together.
But then, something unexpected happened. The yarn began to move! It rolled away from them. Tom and his friends chased after it. They were surprised to find a little mouse playing a joke on them. The mouse had been pulling the yarn the whole time! They all laughed and played together, happy to have a new friend.
