Animal Director, Jeremy, decides to find out exactly how much weight orang-utan Oshine has lost since she came to the park from South Africa. Chimp Hananya is taken by surprise when he meets new arrival Kiki. Baby golden-cheeked gibbon Mikado shows off the latest stages of his colour change. And the work of Monkey World continues with news of two new arrivals.
New arrival Kiki meets her first chimpanzee Patricia after living on her own in a cage in Lebanon for the last eight years. Overweight orang-utan Oshine has a special visitor whilst woolly monkey Bueno is having emergency dental treatment. And there’s sad news about the world’s oldest woolly monkey Xuzy.
Jeremy is on a mission to coax overweight orang-utan Oshine into the great outdoors, but she’s hesitant. There’s trouble at the stumpie house when the boys are introduced to the new girls from Scotland. Baby golden-cheeked gibbon Mikado ventures outside for the first time, and chimp Lulu is refusing her medicine.
There’s serious dental work on a group of stump-tailed macaques from Scotland, and top London surgeon is called in. Meanwhile young ring-tailed lemur Kaiyah from Ireland has her first taste of life in the trees; Harry’s marmosets get a sticky treat and the newest Bachelor Boy Ben, sets his sights high.
The male capuchins explore their new arboreal home for the first time. Alpha male Hananya’s busy showing everyone who’s boss whilst baby woolly Diego joins his family in the big enclosure. There’s great excitement as golden-cheeked gibbon Zoey is pregnant, and the ring-tailed lemurs lap up a sticky treat.
Jeremy’s got high hopes as overweight orang-utan Oshine’s introduced to youngsters Lingga and Dinda. It’s an emotional day when the ugly monkeys recently retired from a research facility in Scotland, go outside for the first time in their lives. And there’s a free-for-all as Hananya’s chimps tuck into some delicious fruit.
It’s a Monkey Life Special as Alison travels to Vietnam for a ground-breaking project. Two golden-cheeked gibbons rescued and rehabilitated at Dao Tien, Monkey World’s sister sanctuary, are to be released into their natural habitat. But will Merry and Lee Lee have the courage to leave their old lives behind.
