The plot they described corresponds with the first and second episodes of "Avatar: The Last Airbender", where the "water people" ( and Sokka) rescue the "air guy" (Aang) while "trapped in a snowy wasteland" (the Southern Water Tribe) with "some fire people are pressing down on them" (Fire Nation Troops and Zuko). The creators of the show intended Aang to be trapped in an iceberg for one hundred years, later to wake inside a futuristic world, wherein he would have a robot named Momo and a dozen bisons. The creators lost interest in this theme, and changed it to one hundred years of suspended animation. The robotic Momo became a flying lemur, and the herd of bison was reduced to one.
