Huey, Dewey and Louie Duck are young white duck triplets who are the nephews of Donald Duck. Known for their mischievous natures and wisecracking personas, the trio have become some of the most iconic Disney characters of all time, making numerous appearances outside their comic debut, often paired with Donald, though they've been paired with Scrooge McDuck extremely often in both comics and animation as well, made mostly popular due to the success of the classic television series DuckTales.
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). According to the Duck Family Tree, their full names are Huebert, Deuteronomy and Louis. 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.
The three ducklings are noted for their identical appearances and personalities. A running joke involves the three sometimes even finishing each other's sentences.
In early comic books and shorts, the caps of Huey, Dewey, and Louie were colored randomly, depending on the whim of the colorist.
On few occasions until 1945 and most every cartoon short afterward, all three nephews wore identical outfits (most commonly red). It wasn't until the 1980s when it became established that Huey is dressed in red, Dewey in blue, and Louie in green. Disney's archivist Dave Smith, in "Disney A to Z," said, "Note that the brightest hue of the three is red (Huey), the color of water, dew, is blue (Dewey), and that leaves Louie, and leaves are green." A few random combinations appear in early Disney merchandise and books, such as yellow, and orange. Another combination that shows up from time to time is Huey in blue, Dewey in red, and Louie in green. In-story, this inconsistency is explained away as a result of the ducklings borrowing each other's clothes.
Huey, Dewey, and Louie also starred in the 1990s series Quack Pack, in which the three were portrayed as teenagers. In Quack Pack, the boys were given distinct personalities, with Huey serving as the group's leader, Dewey as a computer whiz, and Louie as enjoying sports. After Quack Pack, the boys were reverted to their original ages in future appearances, including 2000s series Mickey Mouse Works, and then re-aged in House of Mouse. On House of Mouse, they served as the house band in a variety of different styles (most commonly as 'The Quackstreet Boys').
