PAW Patrol is waiting for new knightly adventures! Puppy Fang finds magical flowers that turn the dragon's breath into ice, and freezes the entire Havkenburg. And the Chaser manages to get the legendary bone of Gavkalibur, and now he becomes a royal knight and tries to interfere with the insidious plans of the Duke of Boltunsky. At this time, Flash and AJ face an equally difficult task - in Axl City, all the toothbrushes have mysteriously disappeared. Will the heroes be able to find the kidnapper and return the loss to the residents?
