Huey, Dewey, and Louie Duck are triplet cartoon characters created in 1937 by writer Ted Osborne and cartoonist Al Taliaferro, and are owned by The Walt Disney Company. Huey, Dewey, and Louie are the nephews of Donald Duck and the grandnephews of Scrooge McDuck. Like their uncles, the boys are anthropomorphic white ducks with yellow-orange beaks and feet. They typically wear shirts and colorful baseball caps, which are sometimes used to differentiate each character.
