One day, a young fish named Bob wanted to swim with his friends. They went to the big pond to play. They were having a lot of fun swimming and jumping in the water.
Then, a police frog named Fred came to the pond. He said, "Hey, kids! You need to be careful when you swim! There are big fish in the pond that can hurt you."
The young fish and the police frog became friends. They played a game of hide and seek. While they were playing, a big fish came near them. The big fish wanted to eat the young fish.
But the police frog jumped high and scared the big fish away. All the young fish were safe and happy. They thanked the police frog and kept swimming, but now they knew to be more careful.
