"Tracker discovers a cave that leads to a lush jungle oasis. In this forgotten jungle, Tracker encounters an amazing variety of unique animals, including tigers, elephants, rhinos, falcons, and more! Danger lurks around every tree and Carlos and Tracker call in some extra help. Ryder and the PAW Patrol arrive in all-new jungle gear and animal-inspired vehicles to help rescue these animals from an impending volcano eruption. Then, the pups encounter a saber-tooth tiger and rescue Sweetie after she sneaks into the Hidden Jungle." -- Container.
