Riri, Fifi et Loulou
In Disney comic writer Don Rosa's continuity, Huey, Dewey, and Louie Duck were born around 1940 in Duckburg. True to his jocular style, Rosa occasionally makes subtle references to the untold mystery of the three boys' life: What became of their parents? In his epic comic series, "Life and Times of Scrooge McDuck", Rosa pictures how Scrooge first met Donald and his nephews, saying: "I'm not used to relatives, either! The few I had seem to have... disappeared!" Huey, Dewey, and Louie answer: "We know how "that" feels, Unca Scrooge!"
