Big Lipped Alligator Moment: Some consider the original illustration for "Oh Susannah!" to qualify as one. The story is supposed to be about a student's roommate being killed, while the illustration is . . . not.
Critical Research Failure: Many of the stories are listed in Schwart's notes as folktales when they actually have direct literary antecedents.
For example, "The Drum" is misattributed as a folktale in Schwartz's notes in the original edition; it's actually a barely modified version of "The New Mother" from the 19th-century English author Lucy Clifford's collection, Anyhow Stories.
"The Wendigo" doesn't much resemble the folkloric monster; that's because it's based on Algernon Blackwood's quite different take on the legend in his 1910 short story of the same name.
Ensemble Darkhorse: Harold is easily one of the most recognizable monsters in the series. Having a name and backstory certainly helps.
Fridge Horror: These are typically classified as children's books.
As mentioned under What an Idiot, the family in "The Big Toe" cooks and eats a corpse's toe. What kind of people are these?
The ghostly woman from The Dream was probably right about the inn: Lucy's room has trapdoor shaped carpets and boarded up windows.
Ho Yay: Thomas and Alfred, the two farmers from "Harold."
Also O'Leary and O'Riley, the two dead men from "Ba-Room", exactly why and how the two men ended up dead in the same bed is never explained.
Jerkass Woobie: Harold the Scarecrow. Horrifying as his final deed is, you really saw it coming given how his creators treated him.
Also, in the video for "Clinkity-Clink" the wind noises. Wsstchwsstchwoo!
Older Than They Think: The Bus Stop. According to Mr Schwartz in the book's foreword, this story actually dates *to Roman times*. For the curious it's an adaptation of the Vanishing Hitchhiker legend.
They Changed It, Now It Sucks: The books are being re-released to commemorate the 30th anniversary... with new illustrations. Many people who grew up being terrified by these books and their original, creepy illustrations are not happy.
And adding insult to injury for those who were never able to obtain personal copies of the originals, they have been taken out of print (including the more recent anniversary editions) and online prices are being inflated.
Rejoice! Scholastic Press still sells the original versions (the bowdlerized versions are published by Harper-Collins), and the price spike on used copies has subsided!
Ugly Cute: The illustration of the pale woman in "The Dream" .
The titular character of "Sam's New Pet" is actually pretty adorable in its own way.
Uncanny Valley: The illustrations never leave it. Even relatively innocuous ones like "The Babysitter" are extremely unnerving.
Even when something perfectly normal is drawn, it still manages to look really creepy.
What an Idiot: The family in 'The Big Toe.' Their son pulls a big toe out of the garden, and the family decides to... cook it and eat it.
