One day, a chubby cat named Tim was walking in a room. He saw a desk and thought it was a big toy. Tim was very happy and wanted to play with the desk. He jumped on it and started to bite the desk. Tim thought it was very fun. But, when Tim bit the desk, something unexpected happened. The desk started to shake and make a loud noise. Tim was scared and jumped off the desk. He hid under a chair and watched the desk closely. Then, the desk turned into a big, friendly dog! The dog wagged its tail and looked at Tim. Tim was surprised, but he was not scared anymore. He came out from under the chair and played with the dog. They became best friends and played together every day.
