Actor Allusion: The episode "Pool Shark" had Boo Boo Stewart playing a teenage boy who inherited a shape shifting gene.
Genre Adultery: "How to Bargain with a Dragon" is set in a Dung Ages fantasy world, being a sequel to "The Most Evil Sorcerer" from Nightmare Hour, contrasted with Stine's usual modern horror stories, including the other short stories in this collection.
Keep Circulating the Tapes: Zigzagged. Seasons one and two are available on Netflix (and the show has episodes released on DVD), but the episode "Scarecrow" has the ending where Bobby is turned into a scarecrow along with the scarecrow salesman instead of the one where Bobby burns the scarecrow salesman after he reverts to his original form. If you want to see "Scarecrow" with the "Bobby burns the scarecrow salesman's original form, then walks off into the empty world" ending, then you'll have to comb through the Internet for it. As for the episodes from seasons three (both part onenote from "Grampires" to "Terrible Love" and part twonote from "Seance" to "Uncle Howee") and four, then you'll have to settle for torrent downloading for most of them and video website viewing for the rest, as those episodes haven't been released on DVD yet and Discovery Family doesn't rerun the show anymore.
Playing Against Type: Happens to a lot of the actors who are on the show, sometimes even in comparison to characters they played in other episodes. Specifically:
Tom Kenny as Uncle Howie, which is not only one of the rare times Kenny has done live action (the other times were on the sketch shows The Edge and Mr. Show), but also shows Kenny playing a cartoonish and goofy character in yellow as a villain rather than as a protagonist (like on SpongeBob SquarePants) or as comic relief (as seen with Heffer Wolfe on Rocko's Modern Life).
Screwed by the Network: In spades. Despite being a very popular show, having amazing ratings, and even plans for a fifth season (or sixth, if you believe part two of season three is a separate season), The Hub changing over to Discovery Family pretty much killed this show's chance of ever continuing. After the Christmas Episode "Goodwill Toward Men," the series was taken off the schedule and R.L. Stine himself said on his Twitter that the show was canceled and no new episodes were going to be made.
Talking to Himself: As mentioned above, Tom Kenny not only plays Uncle Howee on the episode of the same name, but is also the voice of the rabbit puppet, Loomis, and they interact with each other throughout the episode.
Why Fandom Can't Have Nice Things: In-Universe example with Brush With Madness: Alan Miller became a Reclusive Artist after being stalked by a homicidal fan eight years prior to the episode's story and snapped at Corey because he foolishly said "I follow you on Twitter" (though why a reclusive artist would be on a social media site like Twitter is a mystery).
