Chief and Rockapella in “Unfinished Business”

This is Robocrook.

(singing) Robocrook

A rebel of trouble who clinks and clanks for Carmen Sandiego. His last known whereabouts: Australia. You can call koalas cute and cuddly. Just don't call them bears. The lovable koala is a kind of marsupial, a mammal that carries its babies in a pouch, and like many marsupials, koalas are found wild only in Australia, where they've become a national symbol. But times are tough for koalas these days. Home and road building have destroyed most of their habitat, which koalas need for their special diet of eucalyptus leaves. This and other problems now threaten the koalas survival. But things got even worse today when Robocrook popped into Australia and stirred up some strife. Never want to give anybody a fair shake, the recidivist robot have branched out into collapsing koalas. He poached 'em, he pouched 'em, and then he pounced away. Gumshoes, muzzle that mechanical marsupial and crack today's case...

(singing) Woo-woo-ooo-oo

...FOLLA THAT KOALA!
