This story follows the kind rabbit Uncle Wiggily, who encounters a boy notorious for throwing things at animals. Despite being hurt by the boy's snowball, Uncle Wiggily later overhears the boy suffering from an earache and needing cotton for relief. Demonstrating forgiveness and resourcefulness, Uncle Wiggily gathers cotton-like fluff from horse-chestnut buds and secretly leaves it on the boy's doorstep. When the boy realizes the rabbit he harmed likely helped him, he feels remorseful and vows to change his ways, providing a gentle lesson on the power of kindness and empathy to inspire positive behaviour change.
