Plot synopsis


Krang and the Shredder demand to the governments of all the countries on the Earth surrender to them. When the governments reject, Krang and the Shredder set up a massive orbiting mirror in Dimension X to bath the Earth in a steaming heat. The extensive heat causes the polar ice to melt and also starts to evaporate the world's water supply.

When the Shredder's mother Miyoko hears about her son's plans from her retired home for villains, she decides to join him.

The Ninja Turtles get help from General Yogure and together board a space shuttle to go to Dimension X to stop Krang and the Shredder. Before they leave, Splinter gives Donatello an abacus because the computers on board the shuttle may not work. In Dimension X, the TMNT end up in the radiation beam which disables the computers on board the ship. However, Donatello manages to determine an escape route with the abacus Splinter handed him.

When they finally arrive at the Technodrome, Miyoko had set up obstacles in the form of cardboard signs; one of which says it leads to the control room, but actually leads to a garbage compactor. Eventually, the Turtles find their way into the real control room, where Miyoko traps them in a force field. Donatello tries to contact General Yogure to help them, but he ends up captured by Bebop and Rocksteady. Learning from Donatello that Miyoko seems to be infatuated with him, Yogure distracts her by seducing her and trapping her in a force field. This gives the TMNT time enough to destroy the massive orbiting mirror. The TMNT and general Yogure then leave Dimension X and return home to Earth just as the dimensional portal closes.

The Shredder gets tired of his mother because she treats him like a baby, so he transports her back to the retirement home. Back in the sewers, Splinter gives the Turtles a lesson about how faulty modern technology can be.

  • Raphael is missing one of his sai from his belt when he's talking to Leonardo before the Turtles head into the garbage crushing room, and happens again in one shot after they enter it.
  • When Miyoko said the Techndrome was a dump the top of Bebop's mohawk was coloured brown.
  • Raphael's letter on his belt is coloured white after the Turtles crouch on the floor and trip Bebop and Rocksteady through the door.


  • This episode breaks the fourth wall when Michelangelo asks, "Didn't we do this in another episode?" as the Turtles are about to be crushed.
  • The trash compactor that the Turtles are trapped in partly mimmicks the trash compactor scene from Star Wars: Episode IV: A New Hope with Donatello even jimmying the walls in place like Han Solo did in the movie.
  • First time the Turtles go to Dimension X.
