McDuck Mashup is a short animated webcast promoting DuckTales 2017, featuring the series' versions of Huey, Dewey and Louie Duck, Donald Duck, Scrooge McDuck, Flintheart Glomgold, Webby Vanderquack, Bentina Beakley and Launchpad McQuack.
- Scrooge McDuck is seen riding a Chinese Dragon, like in Woo-oo! (2017) and DuckTales - Watch It On HULU Live (2017), although unlike those instances, the dragon is not Pixiu but a different, green-colored one.
- The shots of Scrooge diving into his money are identical to those which opened The Treasure of the Golden Suns (1987), the feature-length pilot of the original DuckTales series, down to Scrooge wearing the same striped bathing suit. The shot is particularly iconic due to having been used in the original series' opening credits.
