Continuity mistake: Up until Green No More in Series 2 (where the Green Ranger powers are destroyed), the Green Ranger's overshield constantly changes between solid-looking metal to flimsy-looking cotton. This is the most obvious difference between the Japanese and US footage.
Continuity mistake: When in Tank mode and Megazord mode, the order in which the Rangers sit is: Billy, Trini, Jason, Kim, Zach. When switching between Tank mode and Megazord mode, Trini and Kim are switched - they are then back to their original seats once the Megazord has been formed.
Continuity mistake: At the start of the episode, Bulk attempts to climb the rope and breaks it, pulling it down with several pieces of the ceiling coming down on top of him. At the end of the episode, this is suddenly all fixed with Trini climbing the same rope. The same gum and dirty spots are all around the top again with the ceiling appearing completely undamaged from before despite Bulk yanking it free and breaking the ceiling. (00:19:25)
Continuity mistake: After Bulk's first attempt to climb the rope, falling to the mat on his butt, Kimberly and Zack are from the overhead view towards the bottom of the screen at the side of the mat. Kimberly is standing away from it, and Zack has one foot on. After Bulk stands up and there's a different angle, suddenly Kimberly and Zack are both on the mat right next to the rope. Jason, Billy and Trini also slightly change positions. (00:03:00)
Continuity mistake: When Skull gets up in Jason's face about the climbing rope, asking if he's saying Bulk can't do it, there is a girl in the background with a red shirt sitting down. In the next shot when the camera pulls back, this girl is suddenly up and walking off to the right of camera. (00:02:33)
Continuity mistake: At the juice bar, Ernie walks up with a tray of drinks and asks who ordered the spinach juice. The shot changes as the ground begins to shake, and suddenly the drinks in his tray are in different positions. Most notably the blue and red cups Switching Places. (00:06:47)
Continuity mistake: When Bulk and Skull interrupt the Karate lesson and push Billy aside. A shot of Jason standing next to the wall has a painting of an umbrella right behind Jason's shoulder. Then when Bulk and Skull walk up to him, suddenly there is a good couple feet distance between him and the umbrella. (00:05:17)
Continuity mistake: After Rita is freed and blows up her dumpster prison, she taunts the astronauts and says she's going to destroy the nearest planet. She's making a hand gesture as she does and then suddenly between cuts she's in a different position. The goons beside her also are in different stances. (00:01:58)
