One day, a little girl named Mia went to the beach with her mom and dad. It was a sunny day, and Mia was happy to play in the sand and water. She built a big sand castle and found pretty shells to put on top.
As Mia played, she saw something in the water. It seemed to be moving in a funny way. Mia looked closer and saw a mysterious dolphin. The dolphin was jumping in and out of the water, making big splashes. Mia thought the dolphin was playing a game with her.
Mia waved at the mysterious dolphin and it waved back with its tail. They played together all day, splashing in the water and having fun. When it was time to go home, Mia said goodbye to her new dolphin friend. She knew she would always remember the fun day she had at the beach with the mysterious dolphin.
