DuckTales
When Donald Duck decides to join the US Navy, he enlists his uncle Scrooge McDuck to look after his nephews, Huey, Dewey, and Louie. Although reluctant to do so due to their hyperactivity, along with his continual pursuit of increasing his wealth and maintaining harsh business ethics, he eventually warms to them upon seeing how smart and resourceful they are, and takes them into his manor as well as a number of adventures. In addition to them, the show features frequent appearances by Gyro Gearloose, an established comic book character, as well as guest appearances by Donald in the first season – this was either a full appearance, or in a cameo scene when Scrooge and his nephews read letters he sends to them, and a few minor appearances by Scrooge's old flame, Glittering Goldie, whose character was adapted from the comic books. The show introduced new characters to the Duck universe; while some were minor including: the nanny Mrs. Beakley, whom Scrooge hires to babysit the nephews; Mrs. Beakley's granddaughter Webby; Scrooge's pilot Launchpad McQuack; Doofus Drake, an admirer of Launchpad and a close friend of the nephews; and the McDuck Manor butler, Duckworth. The second season later introduced three new additional characters as part of the show's stories: "caveduck" Bubba Duck and his pet triceratops Tootsie; and Fenton Crackshell, Scrooge's personal accountant who secretly works as a superhero named Gizmoduck.
Donald Duck universe
Duckburg is home to Yarvard University (a play on the universities of Harvard and Yale), an institution more notable for its athletic teams than for its academic achievements. It also has had international students, like the bey of El Dagga from Egypt, who is mentioned in Yarvard's first appearance; "The Mummy's Ring" by Carl Barks from 1943. One of the things the bey learned at the university was that mummies do not eat. Duckburg is also the home of the Billionaires Club of some of which Scrooge McDuck, John D. Rockerduck and, according to some stories, Flintheart Glomgold are influential members. Duckburg also has a Ritz Hotel, first mentioned in Carl Barks' story "Turkey with All the Schemings" (Walt Disney's Comics and Stories #148, 1953) at which Scrooge McDuck had a business meeting with Donald Duck; who was disguised as the Duke of Baloni, the World's Second-Richest Duck at that time. In the same story Scrooge later buys the Ritz Hotel and he still owns it in Don Rosa's story "Attaaaaaack!" (2000).
