Background characters


  • This is the third Halloween episode, the previous two being "Dawn of the Driscoll" and "Night of the Living McFizzles".
  • The title is based off the 2004 Swedish vampire novel and the 2008 Swedish romantic horror film Let the Right One In.
  • The Forbidden Knowledge of the Shadow Warrior in the NinjaNomicon reappears, previously appearing in "Dawn of the Driscoll".
  • The part where Randy throws the NinjaNomicon and sucks the Halloweenja suit into it is reminiscent of the film Ghostbusters.
  • It's revealed in this episode that McFist is creeped out by retro Halloween music.
  • This is Rachel's second speaking appearance and first main appearance.
  • Rachel's line, "The power of cute compels you!" is a parody of the line "The power of Christ compels you!" from the 1973 horror film, The Exorcist, drawn from the Roman Catholic rite of exorcism of a demonic being.
  • The Halloweenja's magic circle is a reference to the Disney cartoon Gravity Falls.
  • In the background, a plastic figure snowman is wearing a hockey mask similar to that of Jason Voorhees from the Friday the 13th franchise.
