Chief and Rockapella in “Unfinished Business”

This is Kneemoi.

(singing) Kneemoi

That problem glob who robs for Carmen Sandiego. Her last known whereabouts: the center of the Earth. Our planet isn't just a big ball of dirt and water. At Earth's surface is a thin layer of rock called the crust, and under that, another thicker layer of rock, some solid and some molten liquid, called the mantle. Below that, about 1,800 miles beneath Earth's surface is the core. Its outer part is liquid but the inner core is a solid hot ball of iron. How hot is it? Oh, about 12,000 degrees fahrenheit at its center. But it's cooling fast, gumshoes, because today, nefarious Kneemoi entered Earth's orbit. She carved and quartered the globe like a Tootsie Pop planet, then slithered in, and slurped up Earth's soft and sweet chewy center. Oh, gumshoes, restore the core and close the book on today's caper...

(singing) Woo-woo-ooo-oo

...EVIL TO THE CORE!
