Once upon a time, there was a light frog named Tim. Tim lived near a river. He loved to jump and play in the water.
One day, Tim met a fish named Sam. Sam was sad. Tim asked, "Why are you sad, Sam?" Sam said, "I want to quit swimming. I want to jump and play like you, Tim."
Tim thought for a moment. He had an idea. "Let's play together, Sam!" said Tim. They played all day, jumping and swimming in the river. Sam was happy again. They became best friends and never quit playing together.
