- Michael Caine's Scrooge is wrathful and physically intimidating, and can be scary as a result, especially since most of the people he's bullying are innocent two-foot-tall Muppets.Every day in every way, Scrooge is getting worse!
- Every scene with the Ghost of Christmas Yet to Come, which is one of the reasons Gonzo and Rizzo abandon the narration till the finale, partly to let the scene play without comedy, but also because they were scared.
- The music that accompanies the graveyard scenes with the Yet to Come apparition is quite spooky as well.
- The Ghost is terrifying, but the looters who go through Scrooge's stuff after his death are also terrifying. Old Joe is literally a Giant Spider in a hat.
- The portal that the Ghost and Scrooge walk through is also pretty terrifying. Also with the deep ghostly wail that can be heard after the two emerge out of it to the next scene, followed by creaking and snapping as the background behind them straightens out from being twisted by the warphole, as if reality itself has been angrily rebuilt into the bed Scrooge is making for himself.
- No doubt that many a viewer saw the Ghost's appearance to be eerily reminiscent of more than a few interpretations of The Grim Reaper.
- While the Ghost of Christmas Yet to Come is intentionally creepy, the child-like Ghost of Christmas Past is accidentally creepy.
- The scene where Jacob Marley's face appears on the door knocker and yells Scrooge's name caught a lot of people off-guard.
- Chains not only appear out of nowhere at one point to constrict Scrooge, but at the end of the number they slither out from the darkness and slowly drag the Marleys into the shadows. The song is briefly interrupted when the chains start strangling them.
- At one point in their song, the Marleys reminisce about the time they evicted an entire orphanage in the middle of winter, then laugh about their evil deeds. Before they can finish laughing, they both shudder in horror at what they did.
- The song the Marley brothers sing is supremely creepy when you read the lyrics.Doomed, Scrooge
You're doomed for all time
Your future is a horror story
Written by your crime
Your chains are forged
By what you say and do
So, have your fun
When life is done
A nightmare waits for you
We're Marley and Marley
- The soundtrack version is no slouch either, as it includes a verse about the Marleys going back to hell where they belong, also included in at least one broadcast version.
And now it's time to part
To go back where they keep our kind
The wretched and the heartless
- Before the Marleys appear, Scrooge was enjoying a snack when the bell suddenly rings. He looks up at it, then hears a creak from the stairs. He thinks nothing of it and tries to resume his snack until the bell rings again, this time lasting longer, and after it stops the fire goes out. Then we see a luminous light from downstairs, along with an ominous chorus. When the bell rings the second time, the camera gives us a Staggered Zoom toward Scrooge, who is now looking unnerved.
- While the moment where Gonzo accidentally sets Rizzo's tail on fire has been known to send the audience into fits of laughter, it has also been known to terrify small children.
Nightmare Fuel / The Muppet Christmas Carol
Rizzo: Ooh, that's scary stuff. Should we be worried about the kids in the audience?
Gonzo: Nah, it's alright. This is culture.
