The young Een rabbit Paipo Plumpuddle was the great-niece of Luka Long-Ears. During the time when Burdock Brown ruled Een as Emperor, Paipo was an important member of the underground resistance movement known as the Knights of Winter. She served on many missions during her time with the resistance, helping rescue countless animals from Burdock's prisons, including Oji and Opi Openheart.

Paipo also participated in the great battle against the monster tribes. Though young and small, she was known for her courage and never-failing desire to do the right thing, no matter how hard the task.
