They are the guardians, that the ancestors created when they were fighting over power in the temple underground, they are like war machines! but if you get caught you get your scarf ripped off, but not all of it, it all depends how long your scarf is on how much they take ^^ That is their true name
It's never really explained in-game but it's a boss-esque creature that rips half of your scarf off if it catches you. You don't get hurt per se, but less scarf = less air time. And the animation is kinda saddening and (shamefully) comical at the same time.
Also, GORGEOUS PIECE! I am envious of your skills <3
