The fourth target, the mysterious Panda King, resides in the Kunlun Mountains of China, where he terrorizes nearby villages by burying them in avalanches triggered by his fireworks. With four of the five members of the Fiendish Five dealt with and locked up by the police, Sly analyzes the collected pages of the Thievius Raccoonus and determines that the final target is Clockwerk, the leader of the Fiendish Five who killed Sly's parents and stole the Thievius Raccoonus. The gang soon discovers that Clockwerk has always stalked the Cooper Clan since its earliest days. Bentley traces the metal used in some of the Fiendish Five's vehicles to a remote volcano in Russia, where the gang heads next. Using special upgrades to the team van, the gang breaches Clockwerk's lair only to discover that Carmelita has been captured. Sly tries to save her but gets gassed by one of Clockwerk's traps.

Sly replies that the Thievius Raccoonus doesn't create great thieves and that it only takes great thieves to create the Thievius Raccoonus and proceeds to destroy Clockwerk's body and head. After the battle is over and Clockwerk is defeated, Carmelita moves to arrest Sly now that
