One day, a girl named Lily went to the museum with her mom. Lily liked the museum because it had many fun things to look at. She saw big animals, pretty rocks, and old things from long ago.
In one room, there was a noisy music box. Lily wanted to hear the music, so she turned the key. The music started to play, and Lily began to dance. She danced and danced, and she was very happy.
But then, something unexpected happened. The animals and rocks in the museum started to dance too! The big animals danced with Lily, and the pretty rocks spun around. Everyone was surprised and laughed. It was the most fun day at the museum ever.
