For the last time in this festive series, Ben Fogle and Kate Humble are at Longleat Safari Park to conclude a magical week of programmes.Today, Ben and Kate are set a secret mission to find out which animals should go on the ‘naughty' list and who should go on the ‘nice' list, but with animals including ferocious tigers, enormous rhinos and naughty monkeys, how can they possibly decide? And what will be in store for the animals on Christmas morning?Out in the safari park, the camels receive a surprise present in the shape of a new member of the herd, but it's a gift that needs to be handled with care. Neils is a young male and is being introduced to a herd of females and an older male. The hope is that in time they will accept the young boy, and he will ultimately become the new breeding male. But these festive introductions could easily turn sour if the herd attacks the youngster.With Christmas day just around the corner, there are still a few animals that Megan McCubbin needs to deliver some festive cheer to, with the goal of enriching the senses and setting them puzzles to solve. The ferrets get served a helping of eggnog, and the turkeys get weighed, but don't worry, they are not on the menu. This weigh-in is to check they are happy and healthy, but they are still reluctant to jump on the scales.Christmas is the most magical time of year at the park, and to round off the series, the passionate and hard-working keepers reflect on the wonderful privilege they have of spending so much time with the animal families that bring us so much joy.
