Cultural references

  • Grim from The Grim Adventures of Billy & Mandy can be seen on a magazine during the flashback scene.
  • In one shot, Elsa, Phantasma, and Sibella are briefly depicted in a style reminiscent of the main characters of Ed, Edd n Eddy (and in that respective order).

Animation mistakes and/or technical glitches

  • None known.

Inconsistencies/continuity errors and/or goofs/oddities

  • It is not clear if Enid was present during the events of Ghoul School.
  • Though Ghoul School featured Shaggy, Scooby, and Scrappy, only Shaggy and Scooby are referenced in this episode. Scrappy is not. Most likely because many people disliked him.
