I got to be involved in a similar surprise, this one was a summer camp pony and the little girl who adored her. I got to find out her favorite color (purple), give said pony an extra good bath (fleabitten grey, too!) and take her up to the camp's main building where she was talking to her family on the phone. I could see when her parents told her to look out the window. It's great just to be involved with a kid's first horse
Why do I work two jobs to support a horse I don't have time to ride?
