- Actor Allusion: In Thanks a Camelot, King Arthur is voiced by John O'Hurley, who has previously played King Arthur in Spamalot. O'Hurley has also voiced King Neptune on Spongebob Squarepants. In the same episode, Matt Danner voices Sir Galahad, a frog who sounds rather like Kermit the Frog as a baby. This likely refers to Danner's actual role as Baby Kermit in the concurrent 2018 version of Muppet Babies.
- Actor-Shared Background: We have Panchito, a Mexican, voiced by Jamie Camil, who's Mexican in real life.
- Cast the Expert: While Tony Anselmo has voiced Donald in virtually everything since the 1980s, Matt Danner said how he was a consultant for each episode in order to make sure he was portrayed as accurately as possible.
- Dueling Works: With DuckTales (2017), another animated action-comedy show based on the extended universe surrounding Donald Duck. It should be noted that the creative team behind DuckTales had little knowledge of this show's production, thus having no effect on anything they did — including José and Panchito's appearance in Season 2 of that show.
- Fake Nationality: Jose's Brazilian accent is done by Eric Bauza, an American-Canadian voice actor. The same also goes for his Scottish accent used for Uncle Scrooge (although, a Scottish accent can be considered to be somewhat of an Old World counterpart of a Canadian accent).
- Ink-Suit Actor: Xandra bears at least some resemblance to Grey Griffin, including her trademark black hair.
- Invisible Advertising: The series had almost no prior announcement, and was released on the DisneyLife app without much fanfare in June 2018, only in the Philippines.
- Meaningful Release Date: The show was released in the Philippines on June 9th, 2018... which was Donald Duck's 84th anniversary.
- The Other Darrin:
- Rather than Rob Paulsen, who had voiced him in House of Mouse, José is now voiced by Eric Bauza.
- Likewise, Jaime Camil takes over Panchito from Carlos Alazraqui, who also voiced him in House of Mouse and Mickey and the Roadster Racers.
- The Aracuan Bird is voiced by Dee Bradley Baker rather than Frank Welker.
- Uncle Scrooge, in his brief cameo, is voiced by Eric Bauza rather than John Kassir (who took over the role in the Mickey Mouse (2013) shorts after Alan Young passed away) or David Tennant (due to this series having started development before DuckTales (2017) did).
- Production Posse: This is the second project after Muppet Babies (2018) to have Dee Bradley Baker, Eric Bauza, Matt Danner, Jessica DiCicco, and Nikki Lytton.
- Relationship Voice Actor: Panchito, Xandra, and the Aracuan bird are Julio, Dr. Mendoza, and the Duendes.
- Role Reprise:
- Donald and Daisy are once again voiced by Tony Anselmo and Tress MacNeille. There's also Jim Cummings as both Pete and Humphrey the Bear.
- In the Japanese dub, Kōichi Yamadera, Ryusei Nakao and Toshio Furukawa reprise their roles as Donald, Jose and Panchito respectively from the dub of the original film and also from House of Mouse.
- Screwed by the Network: The show was postponed an entire year from its scheduled release and made available only in three countries via an app with no advertising, meaning that its intended demographic isn't even aware of it. Fortunately at least Disney+ will stream it, and it has been sporadically aired on Disney Channel in other countries.
- Short Run in Peru: It was released in the Philippines first before anywhere else in the world. It was also released on Disney Channel Asia on January 1, 2019, and eventually to Disney+ in America on November 12, 2019.
- Talking to Himself: Jessica DiCicco voices April, May, and June.
- What Could Have Been:
- The series was envisioned for Netflix, but was pushed back from release when Disney decided to create their own streaming service.
- Episode 4 would've featured Norse Gods instead of Roman Gods, but Marvel intervened and forbade the staff to use them.
- A minor example, but at 1:06:00 in this podcast, Matt Danner mentioned that Xandra's appearance in the first episode was meant to be at the end of the first act, but it was moved to end of the episode.
- Xandra herself was originally intended to be Atalanta before they chose to make her an original character instead.
