The Turtles find out about the Technodrome and try to find it. Splinter finds the Technodrome and ends up getting kidnapped by Shredder. When the Turtles find the Technodrome, Shredder tells the Turtles who is responsible for covering them in the ooze that mutated them.

The Turtles take over what's left of Baxter Stockman's equipment, to help them track Shredder and the Technodrome and create the turtle Van. Shredder opens a portal to Dimension X in hopes to obtain new weapons. Instead, The Nutrinos - three teenage hot-rodders, and two of Krang's militant Stone Warriors, General Traag and one soldier, come through.
