Sensei Yumi is teaching all the pups the ancient art of Pup-Fu. The Paw Patrol and the mischievous kittens from Mayor Humdinger's Kit-tastrophe Crew are both competing for their belts when they come across an ancient scroll that holds all the secrets of the art. Mayor Humdinger steals the scroll and the Paw Patrol is called upon to find and return it to back to Sensei Yumi. It can be dangerous in the wrong hands, so Chase's drone tracks the sneaky Mayor to his secret lair, while Zuma helps them enter by a hidden cave in the water. Super Pup-Fu student Marshall sneaks in quiet as a mouse and together they get the scroll back where it's supposed to be.
