- When the turtles arrive at the beach and the Technodrome rises out of the ocean, the lettering on the front of the Turtle Van is black instead of white.
- Leonardo and Raphael have opposite colours when Michelangelo tells Shredder to bring them back to Earth to fight them.
- General Traag is seen standing next to Krang even before he opens the portal to allow him and his Rock Soldiers to Earth!

- In the first shot of Krang at the Channel 6 building, yet again, his robot hands are flesh colored.
- The strapping on Donatello's bo is coloured brown when he uses the remote control device to suck the Technodrome into Dimension X.
- After the Technodrome is sucked into Dimension X, Bebop and Rocksteady arrive in a truck. When Krang climbs in, his robot hands momentarily become flesh colored and then turn back to red.
- When April glances down at the broken window, a shot of Rocksteady's legs are shown in place of her own.

For the remainder of the show's run Krang uses use his bubble walker, while the discarded body is put to use in the series finale. Krang returns to using his humanoid body in Turtles Forever. In an ironic reversal, he starts doing so when his bubble walker is smashed during a fight with Shredder.

- Final appearance of the Amphibious Modules.

(Michelangelo on seeing the Great Chaag for the first time)
- Shredder: "No Technodrome, no Rock Warriors, no Foot Soldiers!!! I'll get those Turtles back for this if it's the last thing I ever do!!!"
- Krang: "At this rate, it probably will be the last thing you ever do!"
- Michaelangelo: "Well, compadres, they got away again."
- Donatello: "Yeah, but without the Technodrome, we won't have to worry about them."
- Leonardo: "I don't know, Donatello."
- Splinter: "They still have Krang's know-how and Shredder's cunning and Bebop and Rocksteady's strength. I'm certain we'll be hearing from them again... soon.
