Nightmare Fuel / Total Drama Letterz
Zita's fear challenge, which involved going into a burning building.
Uzuri's scary doll.
Barney falling and breaking his leg.
Nakia's plan to cripple Spider with a pipe.
Mable getting broken glass stuck in her leg from Kasimar sabotaging the pinball machine.
Kasimar murdering one of Eleanor's ferrets.
Uzuri and Yessica trapped in the burning mess hall.
Tabitha's parents, who have an extreme hatred for people they don't consider perfect...which is practically everyone.
Winnie's 'tortures' in the SAW challenge may seem somewhat funny, but taken out of context they become a lot more horrific and seem like real torture.
The hate note Kim writes for Sasha features among other things, her being brutally slaughtered.
Tabitha's Texts from an anonymous source (in fact, her parents) counting down how many days she has left...
Nakia finally snapping, and planning on killing both the contestants and interns, and to make matters worse she gets her hands on a biomechanical spider..
The way she plans on killing them isn't pretty either. She plans on scalping Quana's hair to use as a wig, capturing the remaining contestants and interns, shaving them bald, poisoning them, and burning them alive.
The spider itself, which according to Nakia is incredibly poisonous.
And to top it off, there's no silly warnings from the author this time, showing how serious things become.
In episode 10 of Letterama, Kasimar was going to do something to Tabitha had Rheneas not showed up at the last minute.
Kasimar in general is this. And to make matters worse his gang is implied to still be out there.
The Elimination Method in Starz. They are frozen alive.
The second Elimination Method isn't better; they're hurled via a giant slingshot off the island.
The third Elimination Method involves the eliminated contestant put in a barrel, and lobbed off the island. The first time it happens, it malfunctions, and leaves the former camper with a broken leg.
The fourth Elimination Method involves the campers being thrust into a pipe maze with tons of jagged edges. Not good.
The scene with a Red Fang member and Madeline in the first Kasimar's Quest. It definitely shows this side plot wastes no time in going into some very dark places. The entire chapter is one of the darkest in Letterz Starz, but that scene stands out.
Somebody took Eleanor hostage after she got eliminated. (S)he has told Jimmy, and is giving him the chance to save Eleanor. If he tells anyone, Eleanor dies, and he has until the finale to prevent Eleanor from drowning. Whoever has Eleanor is giving Jimmy clues whenever he passes a trial based on one of the seven deadly sins. In the first trial, the Trial of Sloth, Jimmy must successfully ride a sled down the slope of the thousand foot cliff within four minutes in the middle of the night during a heavy rainstorm. He breaks two ribs in the process. This is NOTPlayed for Laughs.
The second trial involves him burning various family heirlooms with Sasha's cigarettes, which were stolen from him prior. However, Jimmy accidentally set fire to the Mess Hall on Wawanakwa, and barely made it out alive. He is soon found out by Jennifer...
Chris and Chef find a severed human arm in the Wolf Zone on Anatat Island, in which the decapitation was recent...
