The New Masters of Spinjitzu

Following the ninja using the Tornado of Creation, Kruncha and Nuckal are still trapped in the Underworld Ferris wheel, complaining about how the ninja came down and ruined everything. Kruncha then comments on how "they wouldn't be so tough without their magic weapons," giving the skeleton an idea. Moments later, the skeleton generals have escaped their makeshift prison, and head for the mortal world aboard their Skull Truck.
