Chief and Rockapella in “Unfinished Business”

This is Top Grunge.

(singing) Top Grunge

Born to pop wheelies, born to be wild, born to call flimballs, born to smell vile. His last known whereabouts: Göreme Valley, Turkey. Long ago, volcanoes cover the Göreme Valley with a thick layer of ash and a good dose of lava. Over time, wind and water shape the cones' inspires into the lava. People later settled in the odd landscape called Cappadocia, and carved homes and places of worship out of the rock. At its peak in the 10th century, some 40,000 people lived there, many of them religious hermits. In fact, farmers and herdsmen still live in some of the ancient stone dwellings. Or they did until today...

(singing) Crime!

...when Top Grunge grunted into Turkey and sneezed up an evil plan. Using his chopper, and a little leverage, he lift-launched the whole lava landscape and hauled it away. Now he's got a new sport in mind: Cappadocia Motorcross. Gumshoes, grab Grunge and close the book on today's case...

(singing) Woo-woo-oo-oo

...A VOLCANIC CORRUPTION!
