The episode's title is a reference to the Netflix series "Stranger Things."
This episode was produced for season 5 but aired as a season 4 special episode. Because of this, the new opening credits play (which includes Michael D. Cohen as a main character); however, the next episode (Rubber Duck), produced for season 4, plays the old opening credits without Michael D. Cohen.
This episode was produced from July 12 to July 18 of 2018.
This is the second Halloween special in the series, the first being Season 1's Jasper Danger.
The name tag on Ray's costume says 'Cooper,' the name of the actor who plays Ray/Captain Man.
