Once upon a time, there was a big, strong boy named Tim. Tim loved to play in his backyard. One sunny day, he found a jar under a big tree. He was very excited and wanted to see what was inside.
Tim tried to open the jar, but it was too tight. He pulled and pulled, but the jar did not open. He asked his mom to help him. His mom was also strong, but she could not open the jar. They both tried together, but still, the jar did not open.
Then, a little bird flew down from the tree. The bird landed on the jar and sang a beautiful song. As the bird sang, the jar began to open. Tim and his mom were very surprised. The jar revealed a shiny, gold key. They never thought a little bird could open the jar. They thanked the bird and went to find what the key could open.
