query: What are the names of Donald Duck's three nephews?
passage: Huey, Dewey, and Louie
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 bills and feet. They typically wear shirts and colorful baseball caps, which are sometimes used to differentiate each character. Huey, Dewey and Louie have made several animated appearances in both films and television, but comics remain their primary medium. The trio are collectively the 11th most published comic book characters in the world, and outside of the superhero genre, second only to Donald.[1]
