Once upon a time, there was a boy who wanted to prove he was a hero by slaying a fearsome monster—only to discover that the beast, a lonely and magical yeti, merely needed a friend. Bound together by ancient power and a shared love of snowballs, Nunu and Willump now ramble wildly across the Freljord, breathing life into imagined adventures. They hope that somewhere out there, they will find Nunu’s mother. If they can save her, maybe they will be heroes after all… Nunu is a kind, excitable child, eager for adventures and traveling. Having listened to the stories of his mother since he was born, Nunu dreams of being a mighty hero, fighting against terrible foes, and exploring the world. After the loss of his tribe, Nunu felt great sorrow but remained hopeful. Desiring to help his new caretaker Lissandra, and wishing to fulfill his dreams of being a hero, Nunu went to face a terrible beast and prove himself a hero for his people, only to meet Willump and befriend the yeti, the two forming an intense and loving bond. Having been protected by Willump for a long time Nunu is somewhat sheltered from the more complicated and darker aspects of life, he tends to see the best of people, for good or for worst and tries to insert them into his very naive beliefs about the world. Nunu also has hyperactive imagination, often coming up with fantasy ideas to entertain himself and Willump.
