- When Krang says, "Now we march on City Hall!" his robot hands are flesh-colored again.

- 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.

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.

- Krang: "At this rate, it probably will be the last thing you ever do!"
