Chief and Rockapella in “Unfinished Business”

This is Eartha Brute.

(singing) Eartha Brute, huh

A herculean hooligan who hauls heistables for Carmen Sandiego. Her last known whereabouts: Moscow, Russia. Across from Lenin's Tomb on Red Square stands the famed department store called GUM. Its initials G.U.M. stand for a Russian phrase meaning main department store of Moscow. Built under the sun in 1893, the stylish three-story GUM once housed more than 1,000 shops. Its glamour faded though once Communists took power, and GUM became a drab state-run store. But with capitalism now sweeping through Russia, GUM's glory days have returned. But the only sale at GUM today was a huge five finger discount. Eartha Brute, boared with her wardrobe of just one bodysuit, went on a shoplifting spree. That burly burglar marched into Moscow, then strutted out with the store. Gumshoes, track down Eartha in today's caper...

(singing) Woo-woo-ooo-oo

...GUM CLUES FOR GUMSHOES!
