Raven/YMMV


 * Nightmare Fuel - Several instances.
 * Take for example, a scene on the first day of the final week of The Dragon's Eye, in which the remaining contestants, after stepping through the portal to start the final stage of their "quest" in the land of Darkness, were faced with a bunch of screaming Feral Children, who are roaming around the place. These children are said to be people who previously tried to claim the Dragon's Eye but failed. This was more unsettling than scary. But then you realise that the feral children are being played by the previously eliminated contestants who we watched vanishing altogether when they "died". Whether they are intended to be them for real is unclear, but it certainly implied, and the sight of them jeering and laughing at their former teammates, then trying to hold them captive while beating on the doors, still jeering... I'm half surprised there are younger kids still applying to be on this show.
 * Then there's Raven's reaction to it. He's madder than we've ever seen him, threatening Ervan in a way almost devoid of his usual Badass Boast, and openly ranting at and admonishing these feral kids who are so scared of him that they let the contestants out right away. To think that they might have been his former students...
 * Crowning Music of Awesome - The Opening Theme.
 * Narm - You either love the corny, ancient dialogue these guys come out with or you hate it.
 * There's also the final set of challenges within the Castle of Shadows during The Dragon's Eye. After these kids have faced some frankly unbelievable challenges, including scaling cliff faces, crossing raging torrents, and solving difficult riddles, they face the very last challenge before one of them will Reach the Dragon's Eye - this involves reaching into Feely Boxes. You know, those things you put your hands in and there's creepy stuff inside? Very common at parties? Disgusting, yes, but after all they'd done it seemed a bit of a letdown. Add to the fact that in at least one of the boxes (which Raven's voice over described as being filled with "abominable creatures") were a couple of frankly adorable albino hedgehogs.
 * From the same spin-off, Ervan's deadly magical tomatoes. I mean, stones.
 * Narm Charm
 * Scrappy Level - The infuriatingly difficult Way of the Warrior challenge. Just look at it! (Granted, this challenge is designed to be difficult, as it serves as an Elimination Stage at the end of each episode, giving the contestant with the fewest remaining lives one last chance to stay on the quest). Only four contestants have completed the Way of the Warrior to date.
 * A few other levels were like this, such as Dragon's Blood (a balancing level where contestants had to move about two containers of green faux "dragon's blood" on the end of poles, through a maze, without spilling a drop, Troll Trap (involving a cage and high speed movement on the contestants part) and Demon Square.
 * Wizard's Tower also, with the particular challenge of one contestant guiding the other (blindfolded) through a web of string with bells on it. Touch a string lightly and whoosh! there goes a life.
 * Special Effects Failure - Often gets away with it specifically because it keeps the special effects to a minimum. However that means when effects are used (such as the Floating fireball from that one blindfolded challenge) it stands out like whoa. Plus, the men in cloaks aren't all that convincing.
 * You've also got to ignore the safety wires, life jackets etc. Admittedly, they're artfully done.
