- Despite only running for 13 episodes so far, this show manages to really dive into Disney Ducks lore , as well as Disney in general.
- As in the original film, the story starts on Donald's Birthday of Friday the 13th, though the usual bad luck of Donald Duck really kicks into full gear here.
- The music of Donald's frantic taxi ride over to New Quackmore is a little reminiscent of music from the film's train scene.
- Donald's mugshot from the intro of his classic shorts appears while the lawyer explains Clinton Coot's will to the Caballeros.
- The Atlas functions as a more elaborate take on the book from the film that Donald and José use to go to Bahia.
- The Caballeros's first adventure in the Labyrinth of Crete ends with a bullfight against the minotaur, much like the bullfight that ends the original film.
- The characters are able to inflate heads and other body parts in their ghost forms in the underworld, similar to Donald's botched attempt to return to normal size after shrinking in the original film.
- Several to Disney Ducks Comic Universe. Clinton Coot is from the Duck family tree, and the portrait shown of him in the series looks exactly like Don Rosa's drawing of him.
- A portrait of Donald's parents, Quackmore Duck and Hortense McDuck is seen in his burning house, making the same faces they did in Don Rosa's family tree.
- Scrooge McDuck's Money Bin can be seen in a panoramic scene of Duckburg, in the first episode. It later gets a laser blast in episode 12, where Scrooge laments his money pouring out of the resulting hole.
- Panchito's full name comes from the House of Mouse episode "Not So Goofy".
- Clinton Coot has some Scrooge McDuck figurines in the cabana, which Panchito definitely did not break to make room for a pizza box.
- The two homeless kittens that show up at the cabana door bear a strong resemblance to Figaro in Pinocchio and to the orange kitten in Lend a Paw.
- Humphrey the Bear, who starred opposite Donald in multiple Disney shorts, appears in the show starting in Episode 7, as an inanimate bear rug that comes alive when Donald throws a magical "Spark of Life" into his mouth. This is likely a reference to Rugged Bear where he disguises himself as a rug in Donald's house. In the same episode, Spike the Bee, also from Donald's shorts, makes an appearance as well as Donald's doppelgänger from Donald's Double Trouble, now given the name of Dapper Duck.
- In "Shangrila-Di-Da", Donald addresses a voice during his therapy session as "Mr. Spirit", as he often did in Donald in Mathmagic Land.
- Merlin's tower in "Thanks a Camelot!" is the same decrepit wreck it was in The Sword in the Stone.
- Merlin himself bears a resemblance to Professor Owl from the Adventures in Music duology shorts and the Disney Sing-Along Songs video cassettes.
- King Arthur bears a strong resemblance to King Richard from Robin Hood.
- The tiny goblin in Stonehenge Your Bets resembles Creeper from The Black Cauldron, whereas a big cat in the same episode wears the same face as Lucifer from Cinderella.
- In episode 8, José offers to show Mono his watercolor collection, likely referencing the painted portrait of Brazil he had showed Donald in the original Saludos Amigos film.
- In episode 10, the ability to inflate body parts is a reference to the "black magic" scene from the original Saludos Amigos film.
- In episode 12, Donald's anger taking the shape of a hulking giant has been done before in the Mickey Mouse (2013) short "Split Decisions".
