Alison rescues Ruby, a marmoset with attitude and a bit of a weight issue. She has been well cared for but this free ranging marmoset needs company of her own kind. Back at the park there’s a group of primates who’ve had a weight problem in the past, but life is now blossoming for the residents at the stumpie house. Orphan orangutan babies Rieke and Bulu Mata discover the ups and downs of life in the nursery and after some renovations at Hananya’s chimpanzee enclosure, its young Thelma who leads the way.
