Ruff Trigger, an upright version of the Alaskan malamute sled dog, is the premier bounty hunter for Boss Private Investigation Agency (BPIA). Ruff agrees to hunt down the Piglets, aided or hindered along the way by information from his cohorts. In his pursuit, Ruff snaps up 13 bizarre but vicious weapons and maneuvers destructive machinery and vehicles to accomplish his mission. Action takes place on the three planets of the Tyke Galaxy, each full of diverse terrains, elevators and moving platforms as well as high-security and underground areas. Among Ruff's associates are an enchanting but fierce Siamese cat and a strapping desert fox. Adversaries include the enormous police Ratz, the Skul alien guards and the Spygoats of the Secret Service Federation, not to mention other bounty hunters, outlaws and dangerous creatures that populate the Tyke Galaxy. The ultimate dangers, however, lie in the bowels of the corrupt Vanocore Corporation.
