*** Justified with the first film due to it being OvershadowedByControversy, and the latter three because they weren't actually made at the Burbank studio. ''Roger Rabbit'' was mainly animated by Richard Williams' studio in England (the shorts WERE animated at WDAS), ''Nightmare'' was done by Skellington Productions and ''Enchanted'' was animated by James Baxter's animation studio in Pasadena.

** Many people thought that only the films from the canon would be represented, but then the film hits us with the penguins from ''Film/MaryPoppins'', ''Film/PetesDragon1977'', and ''Film/TheReluctantDragon''!

* JustHereForGodzilla: Fans of certain Disney films that are rarely acknowledged by the company such as ''WesternAnimation/TheBlackCauldron'', ''WesternAnimation/AtlantisTheLostEmpire'', and ''WesternAnimation/TreasurePlanet'' are seeing this short since those characters are making their reappearance in years. This was deliberately done by the [[https://www.laughingplace.com/w/articles/2023/06/17/interview-once-upon-a-studio-directors-trent-correy-and-dan-abraham-geek-out-over-disney-animation-history/ filmmakers]] given how they said that some people love those characters.

* SugarWiki/HeartwarmingMoments:
** WesternAnimation/{{Moana}} getting [[WesternAnimation/TheSwordInTheStone Merlin]] to find some water to put [[Franchise/TheLittleMermaid Flounder]] into, which he does by filling [[WesternAnimation/AliceInWonderland the Mad Hatter]]'s hat with water.
** Combined with TearJerker; the scene where Mickey pauses to look longingly at a portrait of his creator, Creator/WaltDisney. For added feels, the scene is accompanied by brief piano rendition of his favorite song, [[Film/MaryPoppins "Feed the Birds"]], and played by none other than [[Music/TheShermanBrothers Richard Sherman]], just as he did for him during the latter years of his life.
--->'''Minnie:''' ''(offscreen)'' Oh, Mickey! Where are you? We're in the lobby!
--->'''Mickey:''' ''(nervous laugh)'' Gotta go. But thanks. ''On with the show...''

** It has been reported that Creator/RobinWilliams' "Lost Boy" from the [[Ride/WaltDisneyWorld Magic of Disney Animation Tour]] short ''Back to Neverland'' makes a cameo.

* VisualEffectsOfAwesome: The fact they were able to use so many characters in their original art styles in such a seamless fashion on the realistic setting of Walt Disney Studio is an admirable feat that has been appreciated by many fans.

* TaintedByThePreview: Many fans are disgusted by Disney's decision to use archival recordings of Creator/RobinWilliams to voice the Genie from ''WesternAnimation/{{Aladdin}}'', especially since Williams' will had a clause that [[https://www.businessinsider.com/disney-cant-use-robin-williams-recorded-material-for-25-years-2015-11 specifically prohibited]] Disney from using those recordings for 25 years after his death, making the move come off as disrespectful. (Even though they did get permission from Williams' estate.) Many have argued that if Disney wanted to have Genie speak, they could've gotten Creator/DanCastellaneta (who is still alive and had been TheOtherDarrin for Genie in ''WesternAnimation/TheReturnOfJafar'', ''WesternAnimation/AladdinTheSeries'', and the ''Franchise/KingdomHearts'' series) or Jim Mesikmen (the current voice of Genie since 2008) to voice him instead.
