One day, a little girl named Lily went to the beach with her mom and dad. She wore her fancy pink dress and her big sun hat. She loved to play in the sand and feel it between her toes. 
Lily wanted to search for pretty shells in the sand. She looked under her feet and found a big, shiny shell. She was so happy and showed it to her mom and dad. They smiled and clapped their hands.
But then, something unexpected happened. The shiny shell started to wiggle! Lily put it down on the sand and it opened up. Inside was a little crab! The crab waved its claws and danced around. Lily and her family laughed and had so much fun with their new crab friend.
