An elephant calf, Indali, is born at Chester Zoo, but her young half-sister Nandita doesn't welcome the new arrival. Bush dog dad Franco is under pressure as his family grows, and Apple, an onager - a very rare type of wild horse - faces a major operation. Asian elephant Sundara has been pregnant for 22 months. She's exhausted, and her mood isn't being helped by the herd's only juvenile, one-year-old Nandita, who keeps disturbing her while she's trying to sleep. When Sundara finally goes into labour, Nandita keeps putting her trunk where it isn't welcome. And when the calf, Indali, is born, there is concern when she doesn't stand up for several minutes. Meanwhile, bush dog dad Franco and his partner Mana have had eight pups. Bush dogs are semi-aquatic small dogs from South America, and are normally monogamous.
