Robert Irwin travels back in time with his real-life best friend, in his third wild adventure
Robert and his best friend Riley are visiting the Canadian badlands in Alberta with Riley's Uncle Nate. The badlands are home to more than 35 different species of dinosaur fossils. Robert and Riley get pulled back in time to Alberta, Canada during the Late Cretaceous period, to find a heavily armored euoplocephalus trapped in vines. The rescue doesn't go according to plan when a ferocious gorgosaurus arrives on the scene, looking for a snack.
