Gotta clarify a bit what happened here, as those that were there have said more about what happened on Twitter that isn’t seen in the video.
The toddler/small child with the balloon started rushing towards the horse, Merida and handler CMs while their parents weren’t fully paying attention. The dad was able to just catch his child with a fast grab, but in doing so, the child lost hold of their balloon, with the momentum flying it towards the horse’s legs. The handlers walked the horse offstage with the balloon still tied around their legs. Haven’t been able to confirm how the horse is doing.
This could have been very bad for all involved. As it is, horses have a rough time walking on pavement and are more prone to slipping as traction is harder. The pavement is already bad on their legs from the shock of striking their hooves down from their immense weight. If the horse had slipped...
Merida was right to get out of the way as promptly as she could. It’s not a laughing matter.
It was a freak accident, but could very easily happen again. Guests are an unpredictable variable - small children even more so. Perhaps Disney could have more CMs walking between the cavalcade and guests, but that wouldn’t exactly work with social distancing.
People are now calling for the ending of using horses in live entertainment in the parks like this, others are saying that Disney should stop selling balloons, or even both. In any case, this was an awful incident coming at a time when the public is already critical of the parks re-opening. Something is going to have to change to make sure that this never happens again.
