Once there was a little boy named Joe. He was 3 years old and he loved to explore. 
One day, Joe was in the garden, being very careful, when he saw something funny. It was a big box and it looked like there was a mystery inside. Joe couldn't help but be curious.
"What's inside the box?" Joe asked his mom.
"I don't know, let's open it and find out," she said.
So Joe's mom opened the box and after a few moments of searching, she found something special. It was a puppy! 
Joe was so happy that he couldn't help but cry. His mom picked up the puppy and said, "Let's take him home." 
So Joe and his mom took the puppy home and Joe named him Mystery. He was very careful with Mystery, and they played together all the time. 
Joe never forgot the mystery in the box, and his happy tears when he got Mystery as a present.
