Alright, so I have read through the thread, probably just going to leave my two cents.
It really is not good that this happened, its super unfortunate, and Im glad that the girl is okay now (if you look on comments on the youtube video, the mom says that she is)
Ive seen this parade many times, and have danced along with it many times, and the moves are not that high impact, the dancer definitely jumped and spun harder than he should have if there was not that much space around him. In his defense, he definitely didnt know that the girl was there, and she was wandering around a bunch of space, not necessarily dancing in one spot, so he didnt really have a chance to see her. In her defense, he should definitely be aware of his surroundings when hes dancing around children like that.
He stopped to apologise, and then yes, continued to dance, because he is probably not supposed to stop dancing, thats his job, there are PLENTLY of other parade control cast members, and there are even a couple of more official looking ones in business clothes, in the hub and just at the end of Main Street while Move It Shake It goes on, he could have easily called one of them over, or the parents could have. If he didnt, then that is his fault, and for all we know, another CM might have come over to check, the Mom was doing the very Shes okay, youre okay that you do to a child to calm them down, and probably calm herself down, she may have even shooed away another CM by saying that and just made the decision to leave the park.
An incident report *should* have been filed by the parade dancer, or whoever was responsible for those type of things asap, or at least been reported to a manager.
First aid in the park should have been recommended by a cast member, whether that was offered or not, we do not know. It would have been the smart thing to do something before leaving the park, but she may have thought that everything was fine, and then after the black eye surfaced, decided something needed to be said.
In terms of the incident itself, as I said, the performers should always be aware of what is going on around them, but if you have small children, wander-dancing through a dance party like that, you should be aware of whats going on around them as well. Theres a matter of risk of injury every time theres a performer or a costumed character around, whether they get hit, get stepped on by Goofy, or bonked with Donalds bill, theres the risk of collision because of the limited visibility. He definitely should have called over another cast member before continuing to dance, and for all we know, maybe he did, maybe he didn't, but they are probably told to just keep dancing, there are other cm's who are trained to deal with stuff like that.
Long story short Im just REALLY hoping that this isnt the end of Move It Shake, and I'm glad the girl is now okay.
