More Spy Creatures go undercover in this eye-opening second episode, which looks at intelligence and creativity in the animal kingdom.

In Borneo, Spy Orangutan watches counterparts who have learnt to saw wood and scrub themselves with soap, while in Pennsylvania, Spy Squirrel reveals how his new friends trick unsuspecting neighbours and steal their nuts.

Also, keep an eye out for tiny Spy Termite, who exposes possibly the smartest con artist – a small red-eyed bird known as the drongo, which outwits a mob of meerkats in the Kalahari desert by mimicking their alarm calls and swooping off with their food. Fascinating!
