- Saliguana strangely speaks with a higher pitched/female-like voice in this episode; however, he would use his normal voice from "Putty On The Brain" again when he returns as one of the resurrected monsters in "The Wedding" later in the season.
- Jason David Frank (Tommy) does not appear in this episode, but is mentioned once by Kimberly.
- The Thunder Megazord fight with Trumpet-Top is the first time a Zord is attacked with its own weapon.
- First episode of the season not to feature Tommy Oliver.
- Trumpet-Top calls up illusions of the following monsters: Grumble Bee from Grumble Bee (episode), Saliguana from "Putty on the Brain", Fighting Flea from "To Flea or Not to Flee", Socadillo from "Second Chance", Rhinoblaster from "Football Season", Mantis from "Plague of the Mantis", Stag Beetle from "The Beetle Invasion, and Slippery Shark from "On Fins and Needles". They are all Zyu2 monsters.
- The title of the episode is a play on the 80's synthpop band Orchestral Manoeuvres in the Dark.
- In consulting the computer, Alpha says "Sensors check out, Zordon, there are no monsters anywhere" however, although the majority of the monsters were illusions, Trumpet-Top was real and should have been detected.
- Right before the Red Dragon Thunderzord transforms into warrior mode, RyuuRanger can be seen on its head.
