- Tommy, Kimberly, and Billy morph slightly out of order, with Billy morphing between Tommy and Kimberly.
- Aisha fixed the frequency reverser by seemingly just tucking wires back into the casing.
- Zordon stated that the frequency reverser had to be fired at the source of the frequency malfunction, however the teens fired it at the Rangers as opposed to the actual source, Beamcaster himself.
- If the frequency reverser could work from the Command Center, why didn't Billy just use it from there in the first place?
- The Power Blaster shot an energy sphere (from the yet-unintroduced Power Cannon) as opposed to the usual stream of energy.
- When Rocky picked up the frequency reverser, it was now on the sidewalk instead of the grass, where it was originally dropped earlier.
- When Beamcaster threw some dynamite at the rangers, it was in the colors red, yellow and blue. When Tommy caught it all 3 sticks were orange. when they were tossed back to Beamcaster they changed back to red, yellow, and blue.
- All footage of Jason, Zack, and Trini unmorphed is recycled from "Something Fishy", a season 1 episode, which is obvious as Zack has the original flattop fade worn throughout Season 1 rather than the dreadlocks he wore throughout Walter Jones' actual appearances in Season 2. Additionally, the opening scene with Kimberly and Trini features the original Putties, even though the Z-Putties replaced them at the start of Season 2.
- When the Rangers use the Power Blaster to destroy Beamcaster, it first shoots the usual energy blast before switching to a flaming fireball used during the Power Cannon attack, as this monster was destroyed by it in Gosei Sentai Dairanger.
- During the scene where Tommy tosses back explosives at Beamcaster, the arsenal of the Dairangers can be see behind Beamcaster, as this footage of him is from Dairanger.
- When Skull is hit by the Zedd Waves, instead of reciting "hail Lord Zedd," he says "hail Lord Fred." Lord Zedd's name being mispronounced would become a running gag in the next season.
- Final time the Power Blaster successfully destroys a monster.
- This is the first episode in which ordinary people (Rocky, Adam and Aisha) and not the usual heroes or their allies defended the city, as all the Power Rangers were affected by the monster's spell of Lord Zedd. This happens again in "When is a Ranger Not a Ranger?"
- This is the last episode where Rocky, Adam and Aisha are regular people before they take Jason, Zack and Trini's places respectively as the new Red, Black and Yellow Power Rangers respectively.
- This episode was one of three episodes released in the Morphin Series. The other two being "When is a Ranger Not a Ranger?" and "Lights, Camera, Action".
