Using special 'spy cameras' invented by the wildlife film makers at John Downer Productions, the viewer is plunged into the very heart of the extraordinary lives of over thirty fascinating animals across the world, including langurs, orangutans, meerkats and crocodiles, revealing behaviour that is remarkably like our own. To expose some of the most astonishing animal behaviour ever seen, the team of Spy Creatures go undercover. These robotic look-alikes make all the right moves to not only be accepted by animals but also interact with them, providing revelatory insights into their world. In this four part series, each episode is packed with a menagerie of animatronic Spy Creatures exploring the different aspects of animal behaviour: Love, Intelligence, Friendships and Mischief. The innovative techniques and ambition of the BBC One series are documented in the fifth ''Making Of" episode, where we see the creation of the Spy Creatures and witness their first magical moves before being deployed around the world; from deserts and rainforests to the Polar Regions.
