If you loved Spy in the Huddle (those penguins were utterly adorable) then you'll definitely find yourself fawning over Spy in the Pod. From spy dolphin to spy tuna and turtle, for the first time an underwater menagerie of spy creatures infiltrate the secret world of dolphins. Swimming alongside some of the most captivating and clever animals on the planet, these new spies are always on the move - catching the waves with surfing bottlenose dolphins and speeding with a megapod of spinner dolphins. Plus, David Tennant is back in action to narrate.
