One day, a green bird named Polly went to the park. She saw a swing and wanted to play on it. But the swing was dirty. So, Polly decided to polish the swing to make it clean.
Polly said, "I will make you clean, swing!" She worked hard to polish the swing. Soon, the swing was shiny and clean. But then, a big dog named Max came to the park.
Max saw the swing and said, "I want to play on the swing too!" But Max was too big for the swing and it broke. Polly was sad because she worked hard to polish the swing.
Max said, "I'm sorry, Polly. I will help you fix the swing." So, Max and Polly worked together to fix the swing. When they were done, the swing was even better than before. Polly and Max became good friends and played on the swing together.
