These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: JumpStart Adventures 4th Grade: Haunted Island
"Funny Aneurysm" Moment: Tiffany, if you're familiar with child pageants... consider she's probably in fourth grade. At least fourth graders would, sadly enough, actually be a huge improvement over, say, toddlers.
Nightmare Fuel: As the main page notes, this game is mainly remembered for this; wandering around a dark, creepy island that looks like something made by Tim Burton can be rather frightening. Not to mention the possibility of Repsac appearing at any time...
Paranoia Fuel: Repsac can jump out at any time...even the Labyrinth.
A few challenges try to scare you and say that Ms. Grunkle will jump you if you're too slow.
