In this special episode, silverback gorilla Jurgen introduces us to the human faces of the zoo, talking us through all the fascinating jobs done by the keepers and the vets. Or at least that's what he's supposed to do... His most valuable insights about the humans is that they have 'dangly arms', say hello a lot and can count. But luckily Geoffrey steps in with some useful information about the expert keeping and veterinary staff that look after the animals.

The hunt is on for a new mascot. A popular, photogenic animal to publicise the zoo. Jurgen the gorilla obviously thinks it should be him, but the series narrator wants to meet all the residents, before deciding who the face of the zoo will be. With senior head keeper, Matt away at dancercise classes, Jurgen steps in as a 'knowledgeable guide' to introduce each of the animals - giving his less than accurate opinions along the way.

Who is the most dangerous animal at the zoo? Is it the zebra, the tortoise or the big cats? With keepers having to wear hard hats, ear protection and face visors around the birds, the rumour is that they are the most dangerous. Risky residents include the wattled crane, fish owl and lorikeet, but silverback gorilla Jurgen is unconvinced. Until he has a ferocious run-in with Ivan the speckled pigeon - who really doesn't like being called tiny.
