We do not get any detail which only proves lousy lighting. However, the smell and the two cougar like creatrues strongly suggest a mother Giant Sloth with two well grown cubs. It is certainly Protective enough.
Which is why i am bothering to show you this.
We have thousands of Bigfoot sightings which are pretty conclusive. However, nocturnal sightings are often not overly conclusive and this is a good example of that. A look at its face would have eliminated doubt. In this case it is the cat like cubs that show us. They could also be females but that seems less likely..
