One Zoo Three

The brothers explore the clever ways the zoo's animals communicate. Aaron discovers there is more to a lion's roar, and how will snow leopard Shen react to Tyler's smelly treat? 

The brothers celebrate Mother's Day. It's a big step for snow leopard cub Shen, jaguar Kiera has a break from daughter Inka, and is Tilly the red panda having a baby? 

It's vet day at the zoo. Kanu the penguin gets treated for his unhappy feet, Ellie the porcupine has an injection of confidence, and Xizi the amur leopard receives some sad news. 

The brothers go to work at an awesome German zoo. Tyler discovers the wonders of the rainforest, Aaron goes ape with orangutans, and Cam makes a splash at an elephant pool party! 

The brothers check up on how green they have been. A tiger gets stuck into an old barrel, a ring-tailed lemur has a special sparkly snack, and the brothers search for tigers in India.

Tyler makes gummy treats for the pygmy marmosets, Cam takes Baikal the white tiger to the dentist, and Aaron attempts to stop the camels chewing their home. 

The brothers are delivering healthy greens to all the animals. Tyler's puzzle gives the lemurs food for thought - and who will win the bug hotel build challenge? 

Find out if supersized anaconda Optimus Prime welcomes his new housemate. Tyler tries to outjump a springy serval cat, and Amur leopard Xizi has a big operation. 

Cam helps Amur leopard Luka look for love, Tyler reunites with Khumbu the snow leopard, and Aaron sees the rare black hornbill chick fly the nest. 

Cam weighs Womba the palm-sized possum, Aaron teaches the camel brothers some manners, and Tyler gets Griffin the caracal to take a giant leap. 

On an extremely hot day at the zooo, the white-cheeked gibbons enjoy a puzzling picnic, Spike the bearded dragon visits the vet, and there is a warm welcome set for Kyra the sun bear.
