Once upon a time, there was a small fish named Fifi. Fifi lived in a big tank with many other fish. One day, Fifi was upset because she lost her favorite toy.
Fifi asked her friend, Bubbles, "Have you seen my toy?" Bubbles replied, "No, but let's look for it together." They swam all around the tank, looking behind rocks and plants.
Finally, they found the toy near a big shell. Fifi was so happy! She said, "Thank you, Bubbles!" Bubbles replied, "You're welcome, Fifi!" From that day on, they were the best of friends and always helped each other.
