Spider monkey Kiara becomes a mum for the first time but seems more interested in hanging out with the youngsters than taking on maternal responsibilities. When Kiara's baby's tail's grip on her starts to loosen, keepers are worried that the baby is becoming weak and may fall to its death. Naked mole-rat sisters Leftie and Rightie, who are both pregnant, battle for their mum's throne. As the duelling gets more vicious, a litter of babies is born. But the babies are forgotten in the chaos, and the keepers must find a solution to the conflict. Babirusa Sausu moves from paddock to paddock to mate with Chester's various females. But when he's reintroduced to his old flame Majene, their daughter Sula puts a stop to his mating mission. Meanwhile, baby capybara Henry enjoys having the attention of all the female capybaras.
