Once upon a time, there was a little fish named Fin. Fin was a bit careless. He liked to swim very, very fast. One day, Fin swam so fast that he didn't recognize a big rock in front of him. He hit the rock with a loud "thud!"
Fin's friend, Bubbles, saw what happened. Bubbles was a smart crab. Bubbles knew that Fin hurt his lung, the part that helps him breathe. Bubbles wanted to help Fin feel better. So, Bubbles went to find help.
Bubbles found a kind turtle named Shelly. Shelly knew how to help Fin. Shelly told Fin to slow down and be more careful when he swims. Fin listened to Shelly and Bubbles. He learned to not be so careless. Fin, Bubbles, and Shelly swam together, happy and safe.
