From Vincent Price and Alice Cooper to haunted pyramids and terrifying creatures, Jim Henson’s creations weren’t always sunshine, rainbows, and rubber chickens.
When you think of the Muppets, you probably picture Kermit the Frog, Miss Piggy, Fozzie Bear, and a whole lot of perfectly organized chaos.
But every once in a while, things got downright creepy.
Long before Halloween specials became a regular television tradition, Jim Henson and his creative team were filling our screens with ghosts, monsters, vampires, haunted theatres, and creatures that looked like they had wandered straight out of a nightmare.
And here’s the funny part.
A lot of this stuff was made for family television.
Whether it was The Muppet Show turning into a horror movie, Sesame Street giving us an unexpectedly creepy sketch, or Fraggle Rock exploring the darker corners of its underground world, Henson’s creations occasionally reminded us that puppets could be just as frightening as they were funny.
And when Henson ventured into fantasy films, things got even darker.
So, with Halloween approaching, let’s revisit 10 of the spookiest Muppet and Jim Henson moments that fans haven’t forgotten.
Some are genuinely unsettling. Others are hilariously ridiculous.
And a few might have you wondering how you ever slept after watching them.
1. Vincent Price Turns The Muppet Show Into a House of Horrors (1977)
If you’re going to make an episode of The Muppet Show scary, who better to invite than legendary horror actor Vincent Price?
In 1977, Price appeared during the show’s first season, and the entire production practically transformed into a haunted house.
There were vampires, ghosts, monsters, creepy music, and enough supernatural nonsense to make Kermit seriously reconsider his career choices.
One particularly memorable sketch placed Fozzie Bear and Gonzo inside a spooky Transylvanian castle, where Price arrived as an unexpected visitor.
Then there was the gloriously strange musical number “I’ve Got You Under My Skin,” featuring Behemoth and Shakey Sanchez.
And, of course, Uncle Deadly was lurking around looking absolutely delighted to be involved.
But perhaps the funniest moment came when Price demonstrated his supposed ability to grow vampire fangs.
Kermit responded by revealing his own fangs—and biting the famous horror star!
The whole episode was a brilliant mixture of classic monster-movie atmosphere and ridiculous Muppet comedy.
Creepiest part: The unsettling monster designs and haunted-house atmosphere.
Funniest part: Kermit apparently being a better vampire than Vincent Price.
2. Alice Cooper Tries to Buy the Muppets’ Souls (1978)
Yes, this actually happened.
In 1978, shock-rock legend Alice Cooper guest-starred on The Muppet Show.
And rather than simply singing a few songs and enjoying the usual backstage chaos, Cooper arrived with a rather unusual business opportunity.
He was working as an agent of the Devil.
His assignment?
Convince the Muppets to trade their souls for fabulous riches and worldwide fame.
You know. Normal family entertainment.
Throughout the episode, Cooper was surrounded by grotesque monsters, mysterious effects, and some wonderfully bizarre musical performances.
He performed “Welcome to My Nightmare” and “School’s Out,” bringing his theatrical horror-rock persona into the Muppet Theatre.
Miss Piggy even briefly became a strange-looking creature named Beakie after dabbling in Cooper’s supernatural promises.
But the real star of the episode might have been Gonzo.
While the others were understandably hesitant about signing away their souls, Gonzo seemed considerably more interested in finding a pen.
Of course he was.
Creepiest part: Alice Cooper casually offering the Muppets a deal with the Devil.
Funniest part: Gonzo treating eternal damnation like an exciting career opportunity.
It’s one of the weirdest guest-star appearances in Muppet Show history—and one of the most entertaining.
3. Uncle Deadly: The Phantom of the Muppet Theatre (1977)
Long before Uncle Deadly became the sophisticated, sharp-tongued character modern Muppet fans recognize, he was considerably more sinister.
In an early episode of The Muppet Show featuring Twiggy, the backstage crew began reporting sightings of a mysterious phantom haunting the theatre.
Naturally, Kermit was skeptical.
After all, when you work with Gonzo, Animal, and the Swedish Chef, a ghost probably isn’t even among your top ten workplace concerns.
But this phantom was real.
Or at least as real as anything gets in the Muppet universe.
The mysterious figure turned out to be Uncle Deadly, a blue, reptilian-looking theatrical performer with a rather unfortunate history.
He claimed that critics had destroyed his performance of Othello, and he had vowed to prevent anyone else from performing in the theatre.
His warning was wonderfully dramatic.
“Leave or be doomed!”
Uncle Deadly’s eerie appearance and theatrical delivery made him one of the most memorable monsters from the original series.
Today, he’s more likely to deliver a cutting remark than terrify an entire cast.
But back then?
He looked like something that might crawl out of your television after midnight.
4. The Egyptian Statue That Terrified Bert and Ernie (1982)
Sometimes Sesame Street didn’t need monsters or elaborate special effects to be creepy.
Sometimes all it needed was an Egyptian pyramid.
In a classic 1982 sketch, Bert and Ernie explored an ancient Egyptian tomb.
Bert was fascinated by the archaeological discoveries.
Ernie, meanwhile, was considerably less comfortable.
Things became especially strange when they encountered statues that looked remarkably like themselves.
And then one of the statues started moving.
While Bert explored elsewhere, the Ernie statue began tapping, talking, and responding to the real Ernie.
Naturally, whenever Bert returned, the statue stopped moving.
We’ve all seen this sort of setup in horror movies.
The difference is that this particular mysterious statue eventually joined Ernie in singing “Rubber Duckie.”
Somehow, that made the whole thing even weirder.
The sketch ended with Bert receiving an unexpected surprise of his own when the statue finally spoke in front of him.
Creepiest part: A supposedly lifeless statue suddenly coming alive inside a dark pyramid.
Funniest part: Even ancient Egyptian statues apparently appreciate a good rubber duckie song.
It’s one of those beautifully bizarre Sesame Street moments that managed to be educational, funny, and slightly unsettling all at once.
5. Fraggle Rock’s Terrible Tunnel (1983)
Fraggle Rock was usually a colorful underground world filled with music, friendship, and Doozers building things that the Fraggles immediately ate.
But hidden deep inside those cheerful caves was something considerably more frightening.
The Terrible Tunnel.
In the 1983 episode of the same name, Wembley discovers that an old Fraggle legend might actually be true.
According to the story, the Terrible Tunnel has a horrifying reputation for swallowing Fraggles forever.
Most of the others dismiss the tale as nonsense.
But Wembley has seen enough to believe there’s something genuinely dangerous lurking underground.
What makes the episode memorable isn’t simply the threat of the tunnel.
It’s the atmosphere.
Fraggle Rock normally felt like an enormous playground waiting to be explored.
Suddenly, those same tunnels became mysterious, threatening places where something terrible might happen.
The episode also played with an idea familiar to anyone who remembers being a frightened child: discovering something scary and having nobody believe you.
And for a character as easily frightened as Wembley, that’s an especially uncomfortable situation.
Creepiest part: The idea that something hidden in Fraggle Rock could swallow its inhabitants and never return them.
Even the happiest puppet-filled worlds apparently need their own scary legends.
6. The Muppet Show Becomes a Murder Mystery (1979)
Here’s another example of The Muppet Show taking a concept that sounds completely inappropriate for a family variety program and somehow making it hilarious.
In 1979, Liza Minnelli guest-starred in an elaborate murder mystery.
Kermit played a private detective investigating sinister events at a theatre where performers were being threatened.
And then the bodies started piling up.
Well, Muppet bodies, anyway.
Characters were attacked, suspects became victims, and the mystery grew increasingly ridiculous.
Fozzie appeared as a police officer attempting to solve the case, while Kermit tried to work out who was responsible.
The entire episode was structured like a classic theatrical whodunit, complete with suspicious characters, dramatic revelations, and an increasingly absurd body count.
The real surprise?
The culprits turned out to be Statler and Waldorf.
Apparently heckling the performers from the balcony wasn’t enough anymore.
Creepiest part: Watching familiar Muppet characters become victims of a mysterious killer.
Funniest part: Discovering that the two old hecklers had taken their criticism to an entirely new level.
It’s a wonderful example of the show parodying adult entertainment without losing its ridiculous personality.
7. The Fireys Try to Remove Sarah’s Head in Labyrinth (1986)
Now we’re venturing into Jim Henson’s darker fantasy work.
And things are about to get considerably stranger.
In the 1986 film Labyrinth, Sarah encounters a group of bizarre, furry creatures known as the Fireys.
At first glance, they’re colorful, energetic, and seem like they might belong in some sort of musical variety show.
Then they begin taking themselves apart.
Heads come off.
Arms get removed.
Body parts are tossed around.
And the whole thing happens during an upbeat musical number called “Chilly Down.”
For the Fireys, this is perfectly normal entertainment.
Unfortunately, they eventually decide that Sarah should join the fun.
There’s just one problem.
Her head doesn’t come off.
And the creatures seem genuinely confused about why.
The combination of cheerful music, manic behavior, and detachable body parts makes this one of the strangest sequences in the entire film.
As a child, you might have found it hilarious.
Or you might have spent the next few nights worrying that a brightly colored puppet was going to try removing your head.
Creepiest part: The Fireys cheerfully suggesting that Sarah should remove her own head.
Jim Henson certainly knew how to create characters that were both adorable and deeply unsettling.
8. The Skeksis Drain Life From Their Victims in The Dark Crystal (1982)
If Labyrinth occasionally wandered into nightmare territory, The Dark Crystal practically moved in and redecorated.
Jim Henson’s 1982 fantasy film was a radical departure from the familiar world of Kermit and his friends.
The creatures were stranger.
The atmosphere was darker.
And the villains were genuinely disturbing.
The Skeksis, grotesque rulers of the world of Thra, were among Henson’s most unsettling creations.
With their decaying bodies, elaborate costumes, and sinister expressions, they looked like ancient creatures desperately clinging to power.
And then there was the essence-draining sequence.
In one particularly disturbing scene, an innocent Podling is subjected to a terrifying machine designed to extract its life essence.
The victim is left aged, weakened, and stripped of its former vitality.
The scene isn’t frightening simply because of the elaborate creature effects.
It’s frightening because of what it represents.
The Skeksis are willing to destroy innocent lives to preserve their own.
That’s a considerably darker idea than anything happening backstage at The Muppet Show.
Creepiest part: The helpless Podling undergoing the Skeksis’ horrifying treatment.
The Dark Crystal proved that Henson’s puppetry could tell stories that were genuinely frightening, not merely spooky in a playful Halloween sense.
9. The Grand High Witch Reveals Her Real Face in The Witches (1990)
Technically, The Witches isn’t a Muppet production, but it absolutely belongs in any discussion of Jim Henson’s creepiest creature creations.
Based on Roald Dahl’s novel, the 1990 film featured extraordinary effects created through Jim Henson’s Creature Shop.
And its most unforgettable moment involved Anjelica Huston’s Grand High Witch.
At first, she appears to be an elegant, intimidating woman presiding over a gathering of witches.
Then the disguise comes off.
Her terrifying true appearance is revealed.
Suddenly, the film becomes something closer to a full-blown horror movie.
The grotesque makeup and creature effects are astonishing, particularly when you remember how much was achieved physically rather than digitally.
Unlike the playful monsters of The Muppet Show, the Grand High Witch isn’t interested in entertaining anyone.
She’s genuinely dangerous.
And for children who watched the film when it first appeared, her transformation could be the sort of image that stayed with them for years.
Creepiest part: The reveal of the Grand High Witch’s true appearance.
It’s a powerful reminder that Jim Henson’s Creature Shop could create monsters every bit as memorable as its friendliest characters.
10. Gonzo Spends Halloween in the Haunted Mansion (2021)
After decades of spooky sketches, theatrical monsters, and strange supernatural encounters, the Muppets finally received their first dedicated Halloween special.
Muppets Haunted Mansion arrived on Disney+ in 2021.
And naturally, Gonzo was the perfect character to lead the adventure.
After all, this is someone who willingly fires himself from cannons.
How frightening could a haunted house possibly be?
Accompanied by Pepe the King Prawn, Gonzo accepts a challenge to spend Halloween night inside the legendary Haunted Mansion.
The special features ghostly residents, supernatural encounters, musical numbers, and Muppet versions of familiar Haunted Mansion characters.
But beneath the comedy, there’s a surprisingly thoughtful idea.
Gonzo, a character famous for being fearless, has to confront the possibility that even he might be afraid of something.
It’s a fitting conclusion to decades of Muppet horror comedy.
The monsters are still ridiculous.
The jokes are still wonderfully silly.
And somehow, the experience still has a little genuine Halloween atmosphere.
Creepiest part: Gonzo discovering that being a daredevil doesn’t necessarily mean being free of fear.
Funniest part: Pepe reacting to the haunting with considerably less enthusiasm than his blue companion.
Why Were Jim Henson’s Creations Sometimes So Creepy?
There’s something fascinating about the way Jim Henson and his collaborators approached monsters.
They didn’t always make them villains.
Sometimes monsters were friendly, like Grover and Herry Monster.
Sometimes they were ridiculous, like the bizarre creatures wandering around The Muppet Show.
Sometimes they were genuinely threatening, like the Skeksis.
And occasionally they were all three at once.
Part of the magic was the craftsmanship.
These weren’t simply drawings moving across a screen.
They were physical creatures with fur, feathers, fabric, elaborate mechanical features, and expressions that seemed remarkably alive.
When one of them smiled, you smiled.
When one of them stared into the camera with enormous eyes and an unsettling grin, things could get a little uncomfortable.
And perhaps that’s why so many of these moments stayed with us.
Jim Henson understood that fantasy didn’t have to be completely safe or predictable to be entertaining.
Sometimes a little darkness made the imagination more exciting.
And sometimes, apparently, it made an entire generation suspicious of Egyptian statues.
Which Muppet Moment Scared You the Most?
Maybe you remember Vincent Price turning The Muppet Show into a haunted theatre.
Maybe Alice Cooper’s monsters gave you nightmares.
Perhaps the Terrible Tunnel frightened you as a child.
Or maybe there’s an obscure Sesame Street sketch that still lives rent-free in your head decades later.
That’s one of the wonderful things about classic Muppet and Jim Henson productions.
Everyone remembers something different.
And with Halloween just around the corner, there’s no better time to revisit the weird, wonderful, occasionally terrifying side of the worlds Henson helped create.
