Animal X is an Australian made documentary television series that aired in more than 120 countries. It began in 1997 with its first series of thirteen half-hour episodes. In 2002, Discovery Channel in the U.S. co-produced the 2nd series of 13 half-hour episodes with the creators of the series, Australia's Storyteller Productions, for Animal Planet. At this point Animal X episodes generally had 3 stories, with one exception: "The Skookum Cast". This was a joint expedition between Animal X and the BFRO which discovered the Skookum Cast, said to be an imprint of the body of a bigfoot.
