Spy Pup is immersed in wild dog life to explore their maternal love, while Spy Penguin records the turbulent action of the mating season, as a male Adélie penguin falls victim to a pebble thief that ruins his chances of love for the season.

Spy Orang-utan meets her real-life counterparts in Borneo, to capture how, living close to local people, they have gained unexpected skills in sawing wood and washing with soap, while Spy Termite catches one of the world's cleverest animal tricksters, the drongo, as he tries to outwit a group of meerkats in the battle for food.

Arctic wolves group together to survive in one of the harshest landscapes on earth, a band of hungry mongooses groom warthogs for tasty morsels - before turning their attention to Spy Warthog - and fish help clean hippos' bodies, as well as providing a unique dental service. Meanwhile, crocodiles and dikkop birds take part in a mutual neighbourhood watch against hungry prowling monitor lizards and Spy Rattlesnake captures how prairie dogs and burrowing owls use their language skills to tell the rest of their community of approaching danger.

A colony of Adélie penguins hunker down to avoid a storm, unaware one of them is a thief, out to steal the stones that make up their nests.

A boisterous elephant has a temper tantrum in the mud near the waterhole, chimpanzees have extra-marital affairs and lemurs try out natural highs when they use millipedes as insecticides with some very dreamy side effects.

The spy creatures infiltrate a hippo pod, a nursery of red flying foxes and the secret world of pygmy forest elephants.
