- The Hitcher, the Crack Fox, Old Gregg, take your pick!
- Charlie, the Hubba-Bubba nightmare!
- The Moon, unholy emperor of Uncanny Valley. It... haunts my dreams.
- "When...when you are the moon, you pretty much split people down the middle. Some go: awww, look at the moon up there with his creamy white face. He's all gentle. While others go: UGH! He's a vanilla rapist, get 'im away from my kids."
- There is a terrifying moment in "Electro" when the Spirit of Jazz looks to the camera, and his pupils dilate.
- The Crack Fox. There was a deleted scene (About one and a half minutes in) in which he sings a song about being "a fancy man" and having "a little foxy plan", presumably removed to prevent mass burnings of The Mighty Boosh DVDs.
- Black Frost, good God. Though it becomes Nightmare Retardant when he is easily defeated by the polar bear and yells, "Oooh, crikey!" in a cartoony voice as he gets knocked down.
- Kodiak Jack trying to rape Vince. Howard leaving Vince with Jack was played for laughs, but the Attempted Rape scene was played as surprisingly serious for the nature of the show, and you could really feel the fear in Vince's voice and see it on his face. The camera giving Kodiak Jack a closeup as he came towards Vince especially gives the viewer a sense of claustrophobia and puts them in Vince's shoes.
- "Milky Joe" is a particularly disturbing episode, as it has Howard demanding Vince "offer yourself to me" so he doesn't starve, with Vince backing away in horror until they stumble across some coconuts to eat, and it plays Domestic Abuse dead seriously, as Precious starts hitting Howard offscreen, complete with Howard trying to hide a black eye - Vince even tells Howard that is unacceptable and offers to talk to her, while Howard pleads with him not to make it worse. He then goes back inside the hut to Precious staring creepily at him and apparently arguing with him - we obviously don't hear what she says, but Howard's defensive replies are very unsettling. Even if it turns out the Coconut people were All Just a Dream, it's a very unnerving episode.
- Hell, even her "death" is creepy as Howard pushes her, she falls and hits her head on a rock and coconut milk spills out from behind her like blood.
