The new breeding bull Tusker meets the ladies elephants. The giant tortoises have a new home, with more corners where Mien can escape Sjaak. And brown bear Mincho is locked out of his hiding place. He must learn to hold his own between the other bears and the wolves.

Brown bear Mincho, who can no longer hide in the inner enclosure, confronts the wolves. Polar bear Freedom retreats into her farrowing hole and soon the two cubs scream: less than 30 centimeters long, pink, blind, deaf and completely helpless. Finally orangutan Minggu, 6 months old, finds that she has far to go before climbing independently, but does mother Tjintah think that as well?

With the mandrils your origin determines your place. Children of a low-ranking female also automatically have a low position in the ranking. But young man Kalle no longer wants to go along with that and seeks confrontation. The young clouded leopards grow up. So fast, in fact, that son Badai slowly becomes a danger to his sisters and mother. Elephant bull Tusker has already sired 14 offspring in his previous zoo. He therefore appears to know exactly what to do when female Duna enters her fertile period.

Giant panda female Wu Wen comes into her fertile period two months earlier than expected. Within a period of 72 hours, male Xing Ya must be ready to mate with her. Zebra stallion Kutze is slowly maturing and wants to become the boss of the group. He will fight the current leader. And giraffe Zeus, who was alone since the death of his girlfriend Twigga, is finally getting company again.

The giant pandas Xing Ya and Wu Wen have not paired despite all the efforts of their caretakers. The period in which this should be possible has passed, so it will now take another year before it can happen again. But then Wu Wen still has one last revival. Barbary Macaque Viktor has been found in a city plantation, with a diaper and collar on. He has probably never been in contact with peers. He needs to learn how to act like a barbary macaque. Otherwise, the group, especially alpha male Kees, will forcefully let him know that he is not welcome.
