Once upon a time, there was a regular hippo named Happy. Happy lived in a big pond with his friends. They liked to play and splash in the water all day.
One day, Happy saw a big tree with a swing. He wanted to hang on the swing with his friends. So, he called his friend, Tiny the turtle, and said, "Let's hang on the swing together!"
Tiny smiled and said, "Yes, let's do it!" They took turns hanging on the swing, laughing and having fun. All the other animals saw them and wanted to join too.
Soon, all the animals were hanging on the swing, one by one. They were so happy to play together. And from that day on, the regular hippo, Happy, and his friends had even more fun in their big pond with the swing.
