Fridge Brilliance: Pete acting as a good guy, intending to scare the daylights out of Ebenezer to make him pay Cratchit/Mickey sufficient salary to maintain Tiny Tim's health!
Harsher in Hindsight: Try watching the scene of Mickey at the cemetery after Wayne Allwine's death.note This short was the first time (outside of some brief segments for the 1970's New Mickey Mouse Club) Allwine did the voice of Mickey, no less.
Hilarious in Hindsight: Goofy plays the ghost of Jacob Marley in his attempt to warn Scrooge about what will happen if he keeps being greedy. In one episode of Goof Troop ("Wrecks, Lies, and Videotape"), Goofy poses as a ghost to warn Pete about what will happen if he doesn't change his ways. Sound familiar?
It's Short, so It Sucks: Many people wish that Disney didn't try to cram the story into 26 minutes and made it a full length feature instead.
Nightmare Fuel: The Ghost of Christmas Future is a very sinister-looking Pete, who throws Scrooge into his own grave, and then laughs evilly while Scrooge desperately grips onto the walls of the grave while red smoke and flames rise out of his coffin.
Scrooge: Spirit...Whose lonely grave is this? (The ghost lights a match, and reveals Scrooge's name on the grave. He then uses that match to light his cigar) GoCF: Why, yours, Ebenezer...(knocks him into the grave) THE RICHEST MAN IN THE CEMETERY! (evil laugh)
You read that right. Out of all the adaptations of A Christmas Carol out there, one of the only ones with Scrooge falling into hell is the Mickey Mouse version. (The others being the 1970 version with Albert Finney and Alec Guinness and the 2009 version with Jim Carrey, which was also distributed by Disney.)
Squick: Daisy Duck being the ex-girlfriend of Donald Duck's uncle may strike some as being a bit skeevy.
Averted in a Nordic dub. Rather than using the Dickens names from the story, the dub instead uses the usual character names, except for Daisy who is instead referred to as "Goldie O'Gilt," Scrooge's old flame from the Klondike Gold Rush.
Tear Jerker: While most adaptations show the Cratchits trying to be strong in the future where Tim dies, this version shows them barely being able to hold back their tears. Especially as Bob lays Tim's crutch over his tombstone.
Even worse, the Cratchits are played by Mickey and Minnie Mouse in this version.
Goofy as Jacob Marley. Who can imagine sweet, lovable Goofy as a man who once embezzled from the less fortunate? Some could excuse that with the Rule of Funny that scene applies though. Besides, Goofy shorts like Motor Mania and several of the sports-themed entries back in The Fifties proved that 'nasty' Goofy could work as a concept.
Perhaps Marley!Goofy had been nasty when he was alive. Remember what Scrooge said about him? And the chains he has to wear as punishment?
Daisy Duck as Scrooge's past love is also a little odd, given the age difference between the actual characters, unless you take into account that Young!Scrooge's design is based off of Donald Duck's appearance from the 1950 short Crazy Over Daisy.
Donald Duck as Fred Honeywell. Granted, Donald is Scrooge's nephew, but there's something odd about seeing Donald as such a cheery character that doesn't get angry. (This Fred does get angry when he's thrown out of Scrooge's office, however, showing that he was modified to fit the actor!)
The Woobie: Mickey. He loses a family member to an illness, for crying out loud!
