- The description of Zero's dehydrated face in the book, especially when it's compared to a jack o'lantern. Not to forget the drooping eyes and mouth bit. Yikes.
- The Yellow Spotted Lizards. Just one bite from them ensures a slow and painful death. Some kids were so frightened by the initial description of the lizards that they put the book down and stopped reading after the first page.
- The Film of the Book has Stanley have a close encounter with one when he discovers one crawling up the shower wall behind him. The thing hisses at him and begins chasing him, but just as it leaps toward Stanley, Mr. Sir shoots it dead. It's the only Pet the Dog moment that Mr. Sir has.
- The way Kate Barlow dies after being bitten by one of them, oh God, the way she dies.Kate Barlow died laughing.
- It's made worse in the film. She pretty much commits suicide by picking up the lizard and putting her arm to its mouth.
- The Warden, Mr. Sir, and Pendanski were willing to let the lizards bite Stanley and Zero. And after they realize that the lizards won't bite them, consider shooting them. Adult Fear, since the authorities that are suppose to protect you don't care if you were to live or die.
- It's more or less ambiguous which group the Warden meant when she said they should just shoot them, though either implication won't end well for the kids and even Dr. Pendanski is caught off guard by the suggestion.
- The scratch scar Mr. Sir gets from The Warden is quite creepy. The reason it appeared after he got scratched was because The Warden puts rattlesnake venom in her nail polish.
- Sam's lynching. It's not really elaborated on, but the implications of the time are horrific. In both the book and the film, he gets shot by Trout in his boat; in the former, Kate had convinced him to run before he could be killed, but in the latter, it seemed he was unaware that Trout wanted him dead.
- Even more horrifying; that was Truth in Television. Still, getting shot and killed instantly is a more merciful death than a bunch of neighbors packing a picnic basket to watch you get hung and strung off a tree.
- The sheriff ultimately deserved it, but Kate asking, "You still want that kiss?" and then shooting him in the head, before kissing him is utterly terrifying, as the prison cell inmates in the film can attest.
- The entire premise of Camp Green Lake. You're sent there as an alternative to juvenile hall. It is in a desert that has no green and a dried-up lake. Your task is to dig a hole with a diameter as wide as the length of your shovel, every day, while being watched over by abusive staff, with water at a premium, both for drinking and for showering. Every once in a while you're allowed to write back to your parents...but every letter gets screened and you have to lie about how fun the place is. No wonder the place was closed down at the end of the book.
- The fact that the place was so hellish that Barf Bag was willing to deliberately get himself bit by a rattlesnake just so he wouldn't have to put up with it anymore.
