One day, a little girl named Lily found a mysterious box in her room. She did not know where it came from. It was a mystery. She wanted to know what was inside the box. She tried to open it, but it was shut very tight.
Lily asked her mom, "Mom, can you help me open this box?" Her mom said, "Let's try together." They tried to open the box, but it was still shut. They tried and tried, but it would not open.
Then, Lily had an idea. She said, "Let's ask dad for help." So they went to dad and showed him the mysterious box. Dad looked at the box and smiled. He said, "I know how to open it." He pushed a secret button on the box, and it opened!
Inside the box, there were lots of fun toys and treats for Lily. She was so happy and surprised. The mystery of the box was solved, and Lily had a great day playing with her new toys.
