In this episode see Happy the hippo’s visit to the dentist with some tusk trouble at Taronga Western Plains Zoo, while sister zoo Taronga waves a sad goodbye to Tizga the Fennec Fox who moves in with his new girlfriend at Adelaide Zoo. Staff at Sea World eagerly awaits the arrival of three Dolphin calves and a rare species of Wallaby is rescued from the brink of extinction.

In this week's episode of THE ZOO, a red panda is about to become a first-time mum; an electrical storm leaves a flying fox orphaned; an orangutan faces a cancer scare; and a breeding program hopes to increase numbers of the critically endangered mallee fowl.

The meerkats at Taronga Zoo are expecting big changes. The tiny babies could bring the group closer together or tear them apart. The four female elephants at Taronga Zoo have had enough of Gung, the young bull. In the wild, he'd be driven off into the distance, so in the zoo, he needs to move out on his own. But moving a three tonne elephant bull is a huge task.

In the return episode of THE ZOO, the birth of two snow leopards is fraught with health fears; a silverback gorilla books in for a dental appointment; an orphaned baby wombat seeks a surrogate mum; and a red-bellied black snake must learn not to bite the hand that wants to help him.
