I can't imagine the head rotate without the hoop. I still think it's the hoop that makes the head rotate. It's about time now to reveal the cowbell that is fixed to the hoop and that you probably hit a little hard 🤣I'd be curious to know if the head alone is rotating, or if the head and hoop are rotating together. I don't know why it would have just started, but I can easily picture the claws exerting rotational force on the hoop, and the hoop spinning the head.
Like I say, though, I don't know why it would have just started.
