Once upon a time, there was a loyal dog named Max. Max lived in a big lab with his friend, a kind man who wore a white coat. They played and worked together every day.
One day, Max and the kind man were playing with a big red ball in the lab. Max was very happy. But then, the kind man had to go away for a while. He told Max, "Stay here, Max. I will be back soon." Max sat down and the kind man shut the door.
Max waited and waited. He heard a strange noise outside the lab. Max was scared, but he wanted to see what it was. He pushed the door with his nose and it opened! Max saw a big, green frog. The frog said, "Hello, Max! You found me! I can talk!" Max was very surprised. The kind man came back and saw Max with the talking frog. They all became good friends and had more fun in the big lab together.
