Della Duck (sometimes named Dumbella Duck) is a fictional character created in 1937 by Al Taliaferro and Ted Osborne. She is a core member of the Disney Duck family, as the niece of Scrooge McDuck, the younger twin sister of Donald Duck and the mother of his nephews Huey, Dewey, and Louie Duck. Della is an anthropomorphic white duck with a yellow-orange bill, legs, and feet. In the DuckTales reboot, she typically wears an aviator hat, bomber jacket with a light blue scarf, brown pants, and as an adult, a robot leg. Della is famous for her less temperamental personality compared to Donald and adventurous spirit, and, as a female adventurer and an amputee in the reboot, for being a positive role model to young girls and to children with disabilities.
