* NightmareFuel: The fact that quite a lot of Spider's furniture is ''made out of dead bugs''.
** [[spoiler: The look on Ms. Fly's face when she's bound up in a web, silk covering her mouth, as Spider's approaching, laughing while wielding a knife and fork]]
** [[spoiler: The ghost bugs, Fly included, after she's been killed, looking sadly at a gravestone.]]
** All of these, and then you remember that this book was made for ''children''.
* VisualEffectsOfAwesome: The ghost-bugs were handdrawn and then added in later in Photoshop as a transparent layer, giving them the glow.
