Jen is away on a trip to the Amazon, so leaves behind her robotic assistant Sarah to look after things. But when Sarah accidentally deletes the file containing the call of the chinstrap penguin, Andy has to get to Antarctica to re-record again - with the leading expert on the penguins arriving any minute!

Andy manages to find a chinstrap penguin, but there are many obstacles in their way before the penguin can lead Andy to the rest of its family - a chunk of ice, a leopard seal and a flock of skua birds...

Jen has set up a live video feed to the island of Barbados to see the hatching of some baby Hawksbill turtles. Andy and Mr Hammond settle down to watch them as they emerge from a clutch of eggs buried deep in the sand. But they soon notice a problem - the baby turtles are all headed the wrong way, away from the guiding light of the moon and away from the ocean! It's up to Andy to figure out the problem and save the day - but can he do that without Mr Hammond seeing him on the feed?
