Once upon a time, there was a big rock. This rock had a special mineral inside. Everyone in the town wanted the mineral. They said it could make them happy. One day, a boy named Tim went to the rock. He wanted the mineral too.
Tim tried to pull the mineral out of the rock. He pulled and pulled, but it did not come out. He felt terrible. He thought he was not strong enough. Then, a big man came to help Tim. The big man pulled and pulled, but the mineral did not come out.
Then, something unexpected happened. The rock started to shake. It was mad because people were trying to take its mineral. The rock grew bigger and bigger. It chased Tim, the big man, and everyone in the town. The rock caught them all and put them inside it. Now, no one could have the mineral, and they all felt terrible.
