When Donatello, Michaelangelo, and Raphael return from the video arcade, they discover that Donatello's lab is in disarray and that Leonardo is missing. Meanwhile, stuck in the frozen tundra, Krang locates a highly concentrated energy source just outside the city that he believes will be sufficient enough to enable him to blow the entire planet off its axis, thus causing a shift in the Earth's proximity to the sun that would reverse the entire climate of the planet. While the polar ice caps would melt, thus freeing the Technodrome, it would also cause the city to be plunged into a new ice age, paralyzing it for Krang's conquest. With the aid of his Hyper Thruster, a contraption large enough to jolt the Earth off of its axis, Krang proposes to use the Foot soldiers to transport it to planet's surface and assemble it while Shredder and Krang locate the mysterious energy source. While out on the streets, still searching for Leonardo, the Turtles discover a break-in at the Blow Hard bubble
