Once upon a time, there was a nice cat named Tom. Tom loved to play and jump all day. He had a big toy box with many fun toys. His favorite toy was a soft, bouncy mattress.
One sunny day, Tom decided to spring on the mattress. He jumped up and down, up and down, laughing and having fun. The mattress made a funny sound every time he jumped, and Tom thought it was the best game ever.
Tom's friends, a dog named Max and a bird named Lily, saw him playing. They wanted to join in the fun, too. So, Tom, Max, and Lily took turns springing on the mattress. They laughed and played together, and they all agreed it was a very nice day.
