Chief and Rockapella in “Unfinished Business”

And this is Sarah Nade, Carmen Sandiego's raging wrongdoing rock-and-roller.

Her last known whereabouts: the Indian Ocean. The Earth's crust is made of cold rigid rock, but just because it's solid doesn't mean it stays in one place. The crust in made of 20 or so massive slabs called tectonic plates. The plates float on a layer of molten rock. Their constant movement causes earthquakes and volcanoes and even shifts continents. Take the Indo-Australian Plate for example. Its movement detacthed Australia from Antarctica around 95 million years ago, then just 28 million years ago, it pushed up the Himalayan Mountains. Well, today, tectonic movement got a lot faster because Sarah Nade, using the sonic rumblings of her band music, blasted the Indo-Australian plate loose, gave it the hook, and dragged it away. Gumshoes, you have to undo...

...the SONIC TECTONIC CATASTROPHE!
