Once upon a time, there was a big pool in a peaceful park. Many kids came to play and swim in the pool. One day, a boy named Tim and his mom went to the pool. They saw a man working near the pool. Tim asked the man, "What are you doing?"
The man smiled and said, "I am fixing the pool so it is safe for you to swim." Tim was happy and went to play with his toy boat. He put it on the water and watched it float. 
Suddenly, the pool started to bubble and shake. Tim and his mom were scared. The man who was working stopped and looked at the pool. A big, friendly fish popped out of the water! The fish said, "Thank you for fixing my home!" Tim, his mom, and the man all laughed. The pool was not just for kids, but for the big, friendly fish too!
