Cam, Tyler and Aaron want to hold a superhero-themed party inspired by the secret superpowers of some of the zoo's most incredible animals. Rica the armadillo comes out of her shell to show off her super-sensitive sniff, and Moby the eagle owl performs awesome aerobatics without making a sound. Meanwhile, Bactrian camels Mo and Navas display some serious suction with their super-slurping, and Cletus the dwarf crocodile arrives at the zoo ready to flex his pecs. Aaron reveals the mighty powers of the cockroach, and the brothers take a trip to Uganda to help a conservation project caring for orphaned chimpanzees.

Cam, Tyler and Aaron are at the cat sanctuary helping keeper Briony prepare for the arrival of Luka, an extremely rare Amur leopard. Will the sanctuary's resident Amur leopard, Xizi, be equally excited with her new partner? Aaron gives Shen, the recently born snow leopard cub, his first health check and helps Tyler prepare a tall, meaty task for Kedera the jaguar - but will she rise to the challenge? 

Who will be triumphant as the brothers put Aaron to the test with more wildlife wonders? Tyler is sharpening his sniffing senses with a bird poo challenge, and we discover how to tell the real difference between a snake and a lizard! 

In Uganda, the brothers help a conservation project return some rescued marsh terrapins back into the wild.
