The episode begins with Peter Rabbit feeling tickled after discovering that Little Joe Otter made a queer trail in the snow. He forgets to look down in the Laughing Brook to see where Little Joe went. Peter waits on the snow-covered bank, hoping Little Joe will return to slide down the bank again. He decides Little Joe has gone home and is about to leave when he hears a splash from the Laughing Brook. Looking upstream, Peter sees four swimmers: Little Joe Otter, Mrs. Otter, and their two nearly grown children. They are having fun rolling over in the water, diving, swimming underwater, and moving swiftly with just their heads showing. When they reach the place where Peter first saw Little Joe climb out, Little Joe makes straight for shore. The bank is low there, and Little Joe scrambles out first. Mrs. Otter scrambles out behind him, followed by one young otter, and then the other young otter. They follow the trail Little Joe made in the snow, coming straight up along the bank of the Laughing Brook. They move toward where Peter is sitting. The episode is a chapter from Thornton W. Burgess's book "Little Joe Otter," narrated by Jude Summers. It focuses on outdoor exploration and family interactions in a natural setting. The format is a narrative story with descriptive elements. Key moments include Peter's discovery, the wait, the splash, and the otters' coordinated exit. Recurring themes include curiosity, wildlife behavior, and adventure in nature. The episode ends with the otters approaching Peter, leaving the outcome open.
