The nursery chimps get the better of animal manager Jeremy and there's tension when a baby woolly monkey is born, but is rejected by its mother.

The park experiences its biggest chimp move ever; baby chimps Ash and Rodders have breakfast at home with keepers Emma and Paul; a Russian orangutan orphan needs a family.

Keeper Mike is on a mission in Moscow for a baby orangutan called Joly; in Paddy's chimp group, Eddi has a toddler tantrum.

Orphaned baby orangutan Joly arrives at the park from Moscow, but her new housemate Hsiao-Ning is not pleased to see her; orangutan Ro-Ro gives birth, and animal manager Jeremy captures the incredible moment on camera.

Chimpanzee Charlie has to undergo emergency dental surgery, but the damage is worse than expected; Ro-Ro has trouble feeding her new baby; chimp Seamus has failed to make any friends in Hananya's group.

Carli and Gypsy, the two newest chimp hooligans join the boisterous bachelor group, and Jim and Alison are on a rescue mission to Hungary to collect stump-tailed macaque Koko, who has been living in a pet-shop cage for 20 years.
