One day, a boy named Tim went to the park to play. He saw a big tree and wanted to test how strong he was. He tried to push the tree, but it did not move. Tim felt sad, but then he heard an unknown voice say, "Try again!" Tim looked around but saw no one.
Tim decided to test his strength again. He pushed the tree with all his might. This time, the tree moved a little. Tim was very happy. The unknown voice said, "Good job!" Tim still did not know who was talking.
Then, a little squirrel came out from behind the tree. It was the squirrel who had been talking! The squirrel had a special power to talk like people. Tim and the squirrel became friends and played together in the park every day. The squirrel's voice was a nice surprise for Tim, and they had lots of fun together.
