Once upon a time, there was a cheerful little bird named Bob. Bob liked to fly and sing all day long. He lived in a small tree house that he built with his friends.
One day, Bob found a hammer on the ground. He thought, "I can use this hammer to make my house better!" So, he picked up the hammer and started to hit the wood. As he hit the wood, his house became stronger and nicer.
Bob wanted to make sure his friends could fit in his house too. So, he worked hard with the hammer to make more room. Soon, all his friends came to visit. They all fit in the house and were very happy. Bob was glad that he found the hammer and could make his house better for everyone.
