- The episode on the Donner Party
is easily the darkest in the series. Of particular note is the description of the final rescue operation returning only to find everyone but one person butchered, that person being Lewis Keseberg, who despite his assertations clearly took cannibalism beyond "survival" as he ignored perfectly edible ox legs out of preference for human flesh. - "The Affair of the Poisons" has an unusually dark implication toward the Professor's past.Ryan: Did you ever have a family, Professor?(slow zoom in on the Professor's face as Ryan's voice echoes)Disembodied Child's Voice: Papa, I want a jelly bean!The Professor: I... don't... know...
- Horse's death in "The Great Molasses Flood" is pretty nightmare-inducing. The red stage lighting makes the molasses he's covered in look like blood at first, and his agonized screaming makes the situation even creepier.
- "How Hippo Meat Almost Saved America" is creepy throughout. A new design for the professor coupled with subtly more subdued lighting overall give the episode an Uncanny Valley effect. The Unexplained Recovery of The Professor after his death makes him behave even more combative with Ryan always seeming like he is moments away from snapping especially whenever the strange new box on set is mentioned. It gives the strong feeling that however The Professor came back, he Came Back Wrong. Then at the end of the episode Ryan wins! But instead of a trophy because of “supply chain problems” he gets a bottle of ‘Puppet Lotion’ that The Professor insists he put on. The scene has led to fans comparing him to Buffalo Bill. The Stinger only makes things worse as something stalks Ryan through the Watcher offices ending on an ominous shot of The Professor watching Ryan from a shelf of plushies as the lights fade out and his eyes begin to glow. An even more unnerving thing eagle-eyed fans point out, just right before Ryan turn off the lights of the office, The Professor's eyes twitch to stare directly at you.
- While his scenes are Played for Laughs, the design of the Infinitiger in "The Vietnamese Sisters Who Fought An Empire" is creepy. It's the eyes: he's got three of them, set in the back of the puppet's head to show through the sockets cut in the front to make them look as if they're always staring intently forward out from some deep dark space not even entirely connected to the tiger's physical body, and through the purple lighting that always bathes the stage when he appears, they appear to glow bright yellow.
- The finale of 'The Bloody Life of England's Fastest Surgeon'. Good God. Right, so Ryan wins a puppet vape and passes out. When he comes to, he is tied up and the Professor reveals that he's been a hologram named Concupiscence McNasty this whole time and that he will kill Ryan and inhabit his flesh, even does a song about it. Ryan breaks out with the help of the studio's puppet rats and just as he's about to get the lamp, Concupiscence lunges from behind with a knife...
- The song itself deserves a special mention, being an outright Villain Song by Concupiscence in which he explains, in nauseating detail, his plans to skin Ryan alive and make a skin suit out of him, and to use the leftover excess to make a matching suit and top hat. The ever-increasing tempo combined with Concupiscence and the four new puppets of the season, the Hippo, the Window, the Tiger, and the Cloud being revealed as just guises he wore and joining Concupiscence in gloating and taunting Ryan over his imminent, violent end turns the whole thing into quite the nightmare.
- Concupiscence even makes it clear throughout his song that he's not a skilled surgeon and that Ryan's death will be slow and painful due to this inexperience. Ryan's eyes darting around the room looking for a way out the second the Substitute makes this clear is horrifying to watch as you can see the moment he realizes that he's trapped.
- The description of what happens to any being unlucky enough to be near an asteroid hitting the Earth in The Dreadful Demise of the Dinosaurs. It says a lot that being atomised from the immediate landing is considered one of the better fates.
