As noted elsewhere on this wiki, the Night of the Living Dummy books is about ten times scarier when you consider the situation. They're about dummies (Slappy or Mr. Wood, depending on which book you're reading) attempting to enslave pre-teen girls. When the girls resist him, he slaps and hits them. To top it all off, in one book he demands a bride, a preteen girl, who he gives violent attacks and calls then "love taps".
Also in one of the Goosebumps books; Revenge of the Living Dummy, it is revealed that Slappy hasn't been awake for most of the book so when you think about the time Brittney was pushed the stairs by the dummy, that means that Ethan actually pushed his cousin down the stairs, just for an elaborate joke.
Making the original Adult Fear entry even creepier, Bride of the Living Dummy mentions that the toymaker who built Slappy infused his evil to bring him to life. The way it was written can be interpreted two ways: actual evil powering his life force, OR Slappy has the soul of an older man and his personality giving him life. Considering his treatment of his owners, and especially young girls, it suddenly adds another layer of (probably unintentional) creepy to it.
During Egg Monsters From Mars, the main character, Dana, is locked into a fridge cell and the titular egg monsters wrap all around him, supposedly to protect him from the cold. In the end, the protagonist (a 12-year-old boy) lays an egg while walking on the lawn. This means that the monsters did not really want to protect him from the cold, they wanted to rape and impregnate him.
From the same book, the fate of Doctor Gray. He held the egg monsters captive in the lab and threatened their friend Dana, so the creatures strike back by burying him in a sort of "egg blanket", assumably smothering him. When Dana returns to the lab,though, there's no trace of him, and what happened is left to our imaginations. If these aliens "reward" their friends by impregnating them, what would they do to people they hate, like Gray?
Near the end of Deep Trouble, the villains try to dispose of Billy and his family by locking them in a glass tank and pushing it into the sea. A school of Merpeople show up, and Billy at first thinks they want revenge for kidnapping their friend. Fortunately, the creatures save the heroes after realizing their good intentions. Alexander and the thugs, however, don't have these ideals, and the Mermaids stop them by capsizing their boat. They're never seen again. Dr.Deep should be really grateful he stopped hunting mermaids...
Also in The Curse of Camp Cold Lake, at first you think the girl on the cover is supposed to be Della, the ghost girl that torments poor Sarah Maas all story long. Until you read and find Della looks perfectly normal but is transparent (plus, she died when she ran into the woods and got bitten by snakes. No one has ever died in the lakes of Camp Cold Lake because the counselors impose a buttload of water safety rules. This girl is not transparent and looks like a female version of the Skin Taker fromCandle Cove. The ending implies that Sarah is killed by Brinna in the Mandatory Twist Ending, though Sarah was also killed by a snake, because the story ended with Brinna holding a poisonous snake and asking Sarah to be her buddy.
In The Horror At Camp Jellyjam, King Jellyjam uses child slaves to wash him 24/7 to prevent him from suffocating on his own stench, and if one of them stops even for a moment, he eats them. But no one can work around the clock without food or water or any rest whatsoever. That means that the camp exists not only to acquire new slaves for King Jellyjam, but to replace the ones he eats on a regular basis. In other words, every camper who wins 6 coins is essentially marked for death.
On the subject of this book, what happens to the non-competitive, non-athletic campers like Wendy? Remember when one counselor tells her that the camp's slogan, "Only the Best", is a warning. Do they just get fed to King Jellyjam straight up?
In Stay Out Of The Basement, apparently the plant clone impersonating Dr. Brewer wasn't evil-he genuinely thought he was the real deal, and was just trying to gain a family of his own. Even after Margaret uncovers the truth, he simply begs for his life before his creator cuts him in half. That's right-Brewer just murdered his newest child, right in front of his other children.
According to the Horror Land spinoff books, the Goosebumps books are set in the same universe. Now just imagine the kid protagonists years later, with their own children. How are they going to be protect their own offspring?
At one point in Attack Of The Mutant Skipper visit's Libby's house, where she shows him her own comic collection. But if "Libby" is just the Mutant in disguise and has her own house and possesions, what if the Mutant did something to the real Libby?
Chicken Chicken is horrible enough,but it gets worse when the story implies that Crystal and Cole weren't Vanessa's first victims.
I Live In Your Basement is freakish and bizarre as it is, but when you ask yourself how long Keith and his mother have lived in the basement, how they got down there, and the need for "monsters" to hide away in such tiny, cramped spaces, it takes on a much, muchdifferent atmosphere.
The TV version of The Haunted Mask II implies that the supernatural forces surrounding Halloween are what bring the masks to life. If the masks were all destroyed (save for the main one, which seems indestructible), what's to stop these same sinister entities from possessing children through something else?
In the end of The Cuckoo Clock of Doom - what about all the other people born in 1988?
In Phantom of the Auditorium, the protagonists are snooping around the titular Phantom's lair. They come across a bowl of freshly poured corn flakes, which they then assume to be a sign that the villain is near. This may sound like stupid logic, but it's actually a clever bit of deductive thinking. If someone pours a bowl of cereal and goes a short distance before someone finds it,the cereal would still be fresh. However, if someone were to go a long distance after pouring that cereal, it'd be soggy due to being left for all that time.
A Shocker On Shock Street became increasingly bizarre and insane the further it went on, up to the Erin and Marty robots short circuiting and needing to be shut down. Someone on the "Blogger Beware" website commented on the review that the insanity of the book's events made more sense when one realizes the story is being told from the point of view from a robot that has been steadily malfunctioning, so naturally Erin's perception of the world had become warped and unstable (which started when she asked her dad if her mom was coming on the ride too, and her dad sheepishly dodges the question. During the end, Erin's "dad" said that he knew something was wrong with the Erin robot when she asked about her mom, when she should have known she was built, not biologically created).
In Chicken Chicken, Vanessa turns the protagonists into chickens...because they chickened out of giving her an apology for knocking over her groceries.
At some point, it was mentioned that when Mr. Wood died in the first Night of the Living Dummy book, Slappy became "twice as evil and a thousand times ruder." Take all the books with Slappy in order of publication, (even from different series), and he actually gradually becomes worse and worse, with his pranks and insults getting more cruel over time. As an example, in the second book, one of his more horrible pranks was painting "AMY AMY AMY AMY" all over her sister's wall. In the recent Slappy New Year, he goes after kids with gardening shears and almost gets close enough to draw blood. This may not have been intended on R.L. Stine's part, but this troper found it pretty neat that such a throwaway trivia fact actually held some weight and consistency over such a long publication run.
In Welcome To Camp Nightmare, Uncle Al briefly warns the kids of unseen creatures called "Tree-bears". 34 books later, The Beast From The East features giant blue bear monsters, with one actually climbing a tree on the cover. And yes, they're every bitas dangerousas he mentioned them.
From the same book, Uncle Al states at the end that Earth is a very dangerous place. Since all the Goosebumps books take place in the same universe according to Word of God, he's absolutely right.
Overlaps with Fridge Horror: Harrison Sadler from Ghost Beach plans to trap the ghost kids in a sacred cave. He also has a German Shepard hanging around. This is because he was planning to use it as bait, since the ghosts hate dogs and kill any they can catch. Most of the dog skeletons in the woods were probably from previous failed attempts. Than he meets Jerry and Terry and figures it'd be easier to lure the ghosts with someone they could trust.
Slappy's Nightmare is a Deconstruction of the previous books he's been in. The Night of the Living Dummy books usually follow the following formula: Kid gets dummy (Slappy or Mr. Wood). Mysterious things happen. Protagonist gets blamed. Dummy reveals he's alive, and demands the kid to be his slave, or this continues. Kid tries to prove the dummy did it. Parents don't believe them/dismiss the story/still blames the kid for wrongdoing. Kid finds a way to defeat him/prove he's alive, sometimes to no avail. In Slappy's Nightmare, every single point in the pattern is mocked, averted, inverted, or subverted:
Slappy himself is put in his owner's place, but instead of proving his innocence, he has to maintain the Masquerade and avoid revealing himself. He also has to do three good deeds (which someone else always ruins) and gets a taste of his own medicine when another character keeps accusing him of the wrongdoing.
The mother in this book actually realizes that yes, part of the problems ARE because of the dummy, even if it's more, "Gee, my daughter's been acting weird since this thing came into my house," than "Yes, dear, I know Slappy did it." She even has the thought of locking him in the closet for a time until her daughter calms down/gets help!
Slappy never reveals himself or causes trouble unless his life is threatened: remember, he has to do good deeds, and can't act like the bastard he usually is until the curse is lifted. The ONLY other times he comes to life are to attempt his good deeds (instead of his usual mean pranks) without being seen.
Even in the event that he does attempt to do something bad, he's never allowed to follow through with it, where before, he always did and got away with it.
Neither Slappy, nor the person blaming him, is the real culprit.
In the end, when the REAL threat shows up, Slappy comes to life, not only in front of his owner, but in front of her classmates, and in the process not only PROVES that the one person who knew he was alive was right all along, but in trying to take out his enemy, he hurts his owner and shows his real self in the process, which leads to his permanent destruction...until we learn that this was All Just a Dream and Here We Go Again.
The book also heavily implies Wally, who's even more vicious than Slappy, is actually Mr. Wood, the other dummy from the first book. Considering this is all a dream, and that Mr. Wood is apparently dead, it seems that Slappy is haunted by memories of his brother.
Curse of the Cave Creatures - the hunter path being "harder" makes a bit of sense - the protagonist is implied to be a kid, and of course a kid won't know how to use weapons!
In My Best Friend is Invisible, Sammy reveals his nickname for his genius brother Simon, the "serious mutant", early on in the book. It looks like a throwaway line at first, but the Tomato Surprise at the end, including the description of what they look like, reveals that the line was foreshadowing The Reveal at the end.
The game from The Beast From The East seems incredibly bizarre and nonsensical at first read, but then consider what kind of creatures the Beasts are. A lot of the rules seem to involve feats of great resilience(getting bitten by snakes, eating insects) or resourcefulness(always tagging from the east, finding ways to trick other players). In the end, they let the kids go after it seems like they've "duplicated" themselves. Therefore, it could be the Beasts are Social Darwinists, and judge who lives or dies by strength and intelligence.
The beasts in The Beast From The East are cannibals. Since they presumably don't always have unsuspecting lost children to play with, and since someone has to be the loser of each game, we can assume they eat each other.
