Chief in “Unfinished Business”

Gumshoes, Carmen Sandiego's swarm of swindling swine has struck again. This time, they poked their pilfering paws into Oslo, Norway. The Oslo International Museum of Children's Art is the most expensive children's art museum in the world. Opened in 1986 by Russian émigrés Rafael and Alla Goldin, it's devoted to artwork created by young people aged 2 to 18 from around the globe. The growing collection exceeds 100,000 pieces and includes everything from paintings to a scrap wire bike sculpture created by a boy from Rwanda. But now, this capital of kids creation has been copped. Top Grunge, Carmen's ogre of odious odors, reeled into Oslo, hooked the museum with his bike, and hauled it away. Your mission, gumshoes: put Top Grunge's stink in the clink, return the International Museum of Children's Art to Oslo, and then capture Carmen Sandiego.
