In the final episode, Ben Fogle gets mobbed by a flock of rainbow-coloured lorikeets as they undergo a vital healthcheck. Meanwhile, Kate Humble gets an extremely close-up view of the collection of giant stick insects by using a special camera. Elsewhere, the park is on lockdown as it prepares to move over 30 lions, the biggest collection in Europe, into a new enclosure. But the keepers have no idea how the big cats will react.
