S03:É11 - S03:E11 - Ice Age

A strange meteor strikes the plateau, and the explorers set out to investigate the site of impact. As they near the meteorite, they notice the air becoming colder and colder. At the site of the crater they find a blue-skinned woman, unconscious and freezing to the touch. They bring her back to the treehouse with intentions of nursing her back to health, only later realizing that she may be member to an alien race of cold-blooded humanoids. As the plateau is threatened by an all-encompassing chill, the explorers are targeted by the woman's followers, who are intent of retrieving their queen.
