When Jen accidentally destroys a video of an Arctic fox, Andy takes to the skies in his safari-mobile and heads to the Arctic to re-record the action on his gizmo. But a hungry polar bear and a snowstorm thwart his every move. Can Andy record a new video of the Arctic fox before Mr Hammond notices the old one was destroyed?

Jen is trying to put together an audio database of animal sounds for Mr Hammond's birthday, but one sound, resembling a howl, eludes them. Andy jets off in his safari-mobile to the Sonoran desert in America in search of the mystery sound and the animal that made it. Along the way, he meets a grasshopper mouse and escapes a pack of hungry harris hawks.
