Cole is a prisoner of the Skull Sorcerer. Meanwhile, Princess Vania races back to the surface, where she tells the ninjas and her father what she saw below. The ninjas quickly gather their things and race to Cole's rescue. Deep underground, Cole toils in darkness alongside the Geckles and Munce, whom he discovers are bitter rivals over a past grievance that each side blames upon the other.
