- Defictionalization: The Clothing brand shirt worn by Isaac in chapter 3 can now be bought from Hive Mill, and the Insolent Children shirt worn by Max is available too.
- Fan Nickname: Since the names of people and things are not always revealed right away, the fandom has taken to making their own, often involving as many puns as possible:
- Gorf (the spirit Max fights in chapter 2) was commonly called 'Racist Whale-Frog' prior to his name being revealed on Twitter.
- "Time snake" for Max's spirit. When it was discovered that the name wasn't really accurate (all spirits "stop time" to commune with their human hosts), Zack themself offered Scrapdragon as a replacement, which Max uses later.
- "Montezeusma" for Isaac's spirit.
- Mr. Splendiferous, Splendid, Stupendid and all variations thereof for Mr. Spender.
- "Forge" or "Manvil" for the anvil-headed knight spirit. The former turns out to be canon.
- The black dog spirits are known by a number of variants of "pixhellhound."
- The giant insect with a zipper down its belly which saved Max from falling off the Ghost Train has been dubbed "The Fly."
- "BERG" for Broken Evil Riddle God, the mysterious spirit secretly possessing Max alongside Scrapdragon.
- "Cthumbra" for the shadow spirit inside Spender.
- "Hijeff" for Hijack-possessed Jeff.

- Similarly Named Works: There's also a show on National Geographic titled Paranatural.
- Technology Marches On: As the years have passed since the comic's debut, flip phones like Max's have become less common. Lampshaded in one alt text.
- What Could Have Been:
- Why Fandom Can't Have Nice Things: It was discovered that one could post comments in the "future" by manipulating the site's code. This got out of hand, messing up the comments section; as a result, the comments have been disabled.
- Word of God: The male and female spectrals with Zarei are named Griggs and Savage, respectively. Savage is also the singer of Anarchyopterix, the band mentioned in RJ's backstory.
