Minnie Mouse Created Duffy for Mickey Mouse as he was packing for a long voyage at sea.
Duffy was previously known as "The Disney Bear", Mickey brought his favorite bear to Magic Kingdom Park. Mickey sat in front of the castle wishing that he had a friend with him to share the excitement and magic of the park. Tinker Bell appears and sprinkles pixie dust on Mickey's bear, bringing it to life.
Shellie May is Duffy's best friend.
