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: 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)
Revealing mistake: After the rope breaks and Bulk is on the floor, he and Skull look up as the ceiling dumps pieces onto them. After this, Bulk spits out white dust that's from the ceiling. However before this even happens as he starts to look up, you can see some white on his lips with his cheeks and mouth perched where he already has the powder in his mouth ready to spit out. (00:03:12)
Revealing mistake: For shows like this, sped up footage can be used for effect on people or items to make them seem like they are going faster. However, in the Command Center after Alpha accident'y zaps himself, he starts to flail around the room rapidly with sped up camera. The rangers move out of the way at seemingly normal speed which would mean they were actually moving slowly when filming to make it appear they were normal. This is a good effect, except the sped up camera is given away by the fact the fluctuating lights on the golden poles around the room are flashing at much higher speeds by the sped up footage, giving it away.

Continuity mistake: When the Red Ranger is being held by the giant monster, his right arm goes from trapped to free and back between shots. (00:16:20)
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)
