One day, a boy named Tim went to play in the park. He saw a big, open box. Inside the box, there was a shiny gem. Tim wanted the gem, so he tried to pull it out.
Tim pulled and pulled, but the gem did not move. He felt sad. Then, a little dog came to help Tim. The dog tried to pull the gem too. Together, they pulled very hard.
Suddenly, the gem started to shake. Tim and the dog did not expect this. The gem opened up like a door! Behind the gem, there was a secret room full of toys. Tim and the dog were so happy. They played with the toys all day long.
