  • This is the only time in which Doidle appears with, Vicky, Nicky, Tootie, and Vicky's Father in an episode. 
  • Vicky is unafraid of things that most people would consider scary as she was unfazed by the spaghetti with eyeball and the French arm.
  • This episode reveals that parents of Timmy not had friends before the parents of Vicky
  • Tootie was the only character not to wear the 3-D glasses.
  • This would mark the last time Tootie and Vicky would interact until "A Fairly Odd Summer."

Running Gags

  • Whenever someone puts on the 3-D glasses they see something that is really super scary to them.
  • "Word Play" being used throughout the episode.


  • Vicky's parents act like they've never met Timmy's parents before and vice versa, yet they met in Channel Chasers when Vicky's parents were first introduced. Though this may be due to Timmy wiping his parent's memories of the events that happened in the later episode.
  • The temple arms on Tootie's glasses are missing in many scenes.
  • The Nickelodeon TV Schedule displays this episode as "Timmy's House of Horror".
  • Timmy could have slept in his treehouse instead of Doidle's doghouse.
  • When Timmy's dad says "Hold me, new friends!", the captions say YOU in place of NEW. It's as if Timmy's dad was meanly nice to Vicky's parents.
  • Vicky's room is colored differently than how it did in previous episodes.
