Through the Wormhole with Morgan Freeman

You are a mollusc without a shell. Sea slugs are found in all seas and at all depths, and the little feather dusters there, sticking out? These are your gills; it is thanks to them that you breathe!

Andy jets off in his safari-mobile to the Pacific Ocean, off the coast of Mexico. His mission: to record a male humpback whale singing to replace the one he accidentally recorded over back at Safari World.

Andy heads to Ethiopia in Africa in search of a wolf pack, in order to take some new photos. Along the way, he meets some bearded vultures squabbling over some old bones.
