As night fell, heavy raindrops drummed on the wooden roof above them. The sky grew dark and the wind whistled through the cracks. Thunder rumbled in the distance, low and serious. From somewhere far in the muddy field came the soft, frightened cry of a baby duckling. The five friends froze, then huddled together, their hearts pounding like the rain itself. Pip pressed close to Wooly for warmth. They knew the storm was loud and dark. They also knew the duckling was small, wet, and alone. Their promise rang in each of their hearts. The friends were brave, and they could not stay still while another little one was crying.
