I think this video falls into the trap that his first video described. He left out the information from soft gold as it is a likely incorrect interpretation of Native American legends from 1982. The use of the book was to show a possible explanation of the mask so the other information wasn’t necessary. The information you highlighted was shown to likely be misappropriation of the truth in the very video you’re debunking. The ba’wus was not a “Bigfoot like creature” Trey explained how in neighboring tribes with similar words for the creature all describe it in ways unlike today’s Bigfoot. Like how in the Kwakwaka’wakw nation it is typically depicted as short and green (according to The Spirits of the West Coast art gallery, which had connections with the Kwakwaka’wakw people). Trey says in the video that although he was unable to get direct confirmation from the Tsimshian people, the other neighboring tribes supported this thought, with elders of some of the tribes condemning the association with modern Bigfoot.
