Hoax? Quite likely. The feet and hands, right arm and such seem worn rather than natural. But I have no information and Google helped not a bit.
As a Fortean, I am willing to entertain this clip. The legs and hocked heels are well done in the event it is purpose-blurred CGI.
The short duration certainly speaks to a CGI creation. Rendering is still an issue. (They don’t know about BOXX)
We shall see. Or not.
