* In "Go Yell It On The Mountain: Snow Way Out", Mr. Butlerteon accompanies the main cast on a trip to a ski resort; from there, the episode turns into something straight out of a horror movie. First, Harriet's yelling[[note]](she's fighting with the others after learning that Joan and Confucius are secretly in a relationship) [[/note]] causes an avalanche, which buries the cabin and leaves the clones trapped, with no signal on their mobile phones. Then, the power goes out, leaving them in total darkness -- right as Mr. B malfunctions, turning murderous and [[RedEyesTakeWarning red-eyed]], and begins stalking the students in the dark, threatening to cook their flesh into lasagna. Yikes!

* In “Anxious Times at Clone High”, the theme song starts off playing normally… until it reaches the chorus. That’s when the vocals disappear, the screen turns black and white, and the music shifts to a lower, more menacing key. It’s a truely jarring moment that suits the horror-themed episode quite well.
** The Heebie Jeebie, a [[Film/TheBabadook Babadook-esque]] [[CreepyMascotSuit mascot]] unleashed on the school by Scudworth and Candide. It feeds on the fear and anxiety of the students, (brought on by the stress of the upcoming mid-term final exams) and abducts them, one by one.
