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.
Nobody's Business (comic)
Uncle Scrooge catches sight of his two loafer nephews, Donald Duck and Gladstone Gander, from his Money Bin. Although he feels his fortune is secure in the hands of his chosen heirs, Huey, Dewey, and Louie, he feels he should do something for his other nephews, and decides to put them through a test to see what kind of business they would be good at. He calls Donald and Gladstone to his room, passes five thousand dollars to both, and tells them to return in twenty-four hours to report how they've invested it.
