Once upon a time, there was a fish named Fin. Fin loved to swim all day. One day, Fin felt very sleepy. He yawned and said, "I need a nap."
Fin swam to his favorite spot under a big rock. He looked left and right to make sure it was safe. Fin was happy when he saw no big fish around. He knew it was a good place to sleep.
Fin closed his eyes and started to sleep. He dreamed of swimming fast in the water with his fish friends. When Fin woke up, he felt good and ready to swim again. He swam all day, happy and full of energy.
