  • When Krang is introducing the components of the Hyper Thruster to Shredder his android's hand flashes from red to flesh coloured when it lifts its arm.
  • When Krang says that he's found the dinosaurs' energy source, his android's hands are flesh coloured.
  • Leonardo replaces Raphael when the three Turtles arrive at the rock quarry. He's later seen replacing Michelangelo after they first spot Speega and his friends coming out of their drilling vehicle.


  • This episode should serve as the season opener as the Technodrome is still trapped in the Arctic ice.
  • Second and final appearance of Krang's holographic cloaker.
  • Two penguins can be seen in the Arctic landscape despite the fact that penguins reside in the Antarctic.


  • Shredder: I've had it with your idiotic schemes, Krang. From now on, I call the shots!
  • Krang: Don't annoy me, Shredder...I've had a very bad day!
