Once upon a time, there was a popular fish named Fin. Fin had a big smile and a shiny scale. All the little fish liked to play with Fin.
One day, Fin and his friends played in the sea. They swam and laughed all day. The sun went down, and it was time for the fish to go home. But, Fin's shiny scale was gone!
Fin was sad and worried. He looked and looked for his shiny scale. Then, something unexpected happened. A little crab walked up to Fin and gave him a big hug. The crab said, "I found your shiny scale!" Fin was so happy, he smiled a big smile. The little crab was a new friend, and they all played together.
