Another pseudo-documentary from the same file cabinet as the program that "explored" the question about mermaids (and mermen) being real. At the end of the program people are running around a forest at night, using flares to cast shadows, hearing "mysterious" sounds. Very atmospheric, but it tells us bupkis
about whether such a thing as a yeti actually exists.
Note the IMDB info - this is all staged, "with actors, not real people."
Why does Animal Planet exploit the credulousness of an audience by presenting these pseudo-documentaries without disclaimers? Even Orson Welles told the radio audience that his broadcast of The War of the Worlds was a dramatization, although many people missed the intro and thought they were hearing a news broadcast.
So, approach anything done by Animal Planet with caution...
