In this adventure, the kindly rabbit Uncle Wiggily overhears a group of boys and discovers one intends to cruelly tie a tin can to a small dog's tail, while another boy bravely refuses to help. When the cruel boy threatens the kind one, Uncle Wiggily, hidden nearby, cleverly uses his digging paws to shower the bully with sand and dirt, driving him away in discomfort and allowing the kind boy to comfort the frightened dog. The story highlights themes of kindness to animals, the courage to stand up against wrongdoing, and uses Uncle Wiggily's gentle intervention to show that cruelty can be stopped and perhaps even teach the wrongdoer a lesson.
