They’ll be fine. Most likely they will head for the woods. Then when it is safe to do so they will be checked up on.
I finally saw the movie a couple of years ago, I do not recommend it to anyone who is familiar with the story from the original book. It’s cute movie, but barely resembles the book at all. I read the book when I was in the 1st or 2nd grade.........and that was more years ago than I care to remember :)
First time I went was 1986. My then husband was an ad rep for a local TV station and so we hung out with the camera crew. didn’t go again until 2002, the year before we moved here. Now when we go we do it on Friday to watch them swim back and do it from a boat - it’s really cool!
Who is in a boat? You or the ponies? Enquiring minds want to know.
