Soon he discovers bat-like creatures, controlled by unknown evil forces, which threaten his homeland. He escapes the encounter but will have plenty more to face. Stig must depend on what Mother Nature can provide, along with the help of new friends like Meg, whom he meets on his quest to return home. He's got his mechanical skills and a map that his father had given him. But is that enough to get him back home?
