Della Duck , also variously known as Dumbella Duck and Thelma Duck, is a female anthropomorphic duck.
Della is Donald Duck's blond-haired twin sister. Born like her brother in 1920, Della married an anonymous Mr Duck and had triplets with him, Huey, Dewey and Louie Duck, who were born somewhere around 1935.
In 1937, the still very mischiveious and disobedient Huey, Dewey and Louie had caused a firecracker to go off underneath their father's armchair, landing him in a hospital. Della was a talented air pilot, which did not leave her enough time to take care of her children on her own without her husband's help; she sent them off to live with her brother Donald for a few weeks. Later that year, she also sent them to Donald for a shorter while. Both times, the kids behaved like absolute pests, and it was only begrudgingly that Donald agreed to take them on again in 1938. while Della set on an experimental space flight. Della was not heard of again and eventually presumed dead, Huey, Dewey and Louie staying to live with Donald.
In fact, Della was quite alright; as her spaceship passed near the Earth many years later, it was possible for Donald, Huey, Dewey and Louie to contact her from Earth. It turned out, because of the laws of time relativity, Della's vehicle's great speed was such that she had only felt a few weeks pass. Seeing Huey, Dewey and Louie on the screen, she mused that she had left "three boys" at home, whom she hoped would turn out like them; knowing Della would only return to Earth many years later from their perspective, the Ducks did not have the heart to reveal her the truth before the communication was cut off.
Behind the scenesEdit
Della was first mentioned in 1937 in Donald's Nephews.
The letter from her in the Donald's Nephews comic strip is signed "Cousin Della", oddly enough, rather than "Sister Della". Meanwhile in the 1937 cartoon of the same name, she signs another letter to Donald "your sister Dumbella". In Carl Barks's first Duck Family Tree, she is "Thelma Duck", a name also used in Mark Worden's version. After the printing of Worden's tree, fans wrote to Disney asking why she was "Dumbella" in the cartoon and "Thelma" in the tree; the official answer was that Dumbella had probably changed her name to Thelma by the time the tree was made, due to the embarassment of her previous name. In Don Rosa's Duck Family Tree, her real name is instead given as "Della"; "Thelma" is completely ignored, and "Dumbella" is explained as a childhood nickname of Della that was courtesy of Donald.
