Ben Fogle and Kate Humble get ready to welcome some exciting new VIPS to the park. Five southern koalas are set to become the very first of their kind in Europe. But this groundbreaking mission, more than two years in the planning, is fraught with difficulties. Koalas have never been flown this far in just one leg. Will they survive the epic 15,000km journey? They’re notoriously fussy eaters so has the team picked the correct types out of hundreds of varieties of eucalyptus? If the famous five turn their noses up, the park is in trouble. Elsewhere at the safari park, it’s the dawn of a new era as the pin-up boy of the park, handsome Harry, is being groomed to take the helm of a new pride of lions. Ben demonstrates his curling skills with some giant blocks of ice as he helps the white rhinos to cool down, while Kate puts the sea lions’ swimming talents to the test with an ingenious catapult contraption. Can Half-Mile Lake’s residents reach speeds of 25mph recorded by their cousins in the wild? Jean Johansson is kicking up a stink in wolf wood with a sack of zebra poo to see if the pack of European grey wolves can live up to their reputation for having one of the best senses of smell in the animal world. She also discovers why a giraffe's tongue is such a mighty muscle, and why it might just be handy to have one of those gentle giants around if nettles ever sting you.
