Donald Duck universe
Donald Duck and his maternal uncle Scrooge McDuck received nearly equal exposure in comics. Other primary characters include Donald's three young nephews Huey, Dewey, and Louie, and girlfriend Daisy Duck.
Huey, Dewey, and Louie
Huey, Dewey, and Louie are the sons of Donald's sister Della Duck; in "Donald's Nephews", their mother is instead named Dumbella. In the original theatrical shorts, they were originally sent to visit Donald for only one day; in the comics, the three were sent to stay with Donald on a temporary basis, until their father came back from the hospital (the boys ended up sending him there after a practical joke of putting firecrackers under his chair). In both the comics and animated shorts, the boys' parents were never heard from or mentioned again after these instances, with the boys ending up permanently living with Donald. All four of them live in the fictional city of Duckburg, in the fictional state of Calisota.
