This episode features the birth of Africa's most endangered cat. If the cameras can capture this incredible moment, it would be the first time the keepers have ever seen a live cheetah birth. Jean Johansson helps to settle in a gaggle of new penguins, but will they make a splash with the rest of the colony? Meanwhile, one of Africa's largest antelopes checks into the park, but at just a quarter of the size of his predecessor bull, the keepers are on tenterhooks as he meets his new, much larger lady friends for the first time.
