Once upon a time, there was a big fish named Bob. Bob was swimming in the pond, when he saw a net. Bob was a careless fish and didn't see the net. He swam right into it and got stuck.
A little boy named Tim saw Bob in the net. Tim said, "Oh no! Fish is stuck in the net. I will help you." Tim wanted to remove the net from Bob. He pulled and pulled, but the net was very strong.
Finally, Tim's mom came and helped him. "Be careful, Tim," she said. Together, they removed the net and set Bob free. Bob was so happy and thanked Tim and his mom. From that day on, Bob was never careless again.
