Welcome to the town of Adventure Bay, where you can meet six heroic pups: Marshall, Rubble, Chase, Rocky, Zuma and Skye. Led by a 10-year-old boy, Ryder, they make up the PAW Patrol, and working together as a team they use their different skills to help anyone in need. This time Carlos and Tracker need the help of the six pups on Jack Scalawag's Island. Something very mysterious is going on there. And the merpups need help, too, because somebody stole their magic shell. No job is too big, no pup is too small!
