While the Turtles work on using fragments of the Vortex Crystal to stabilize their mutations, Lord Dregg plans to use the fragments to create another Vortex Crystal to power his Vortex Transporter. Meanwhile, Dregg's second-in-command, HiTech, is blasted into space, to be replaced by Dregg's top scientist, Mung, as his new second-in-command.
