In the scene where Scrooge is with the Ghost of Christmas Past at his school, watching the boys ride by on horses and in the cart, watch carefully. At the beginning of the scene, there is one cart being pulled by a white horse with 2 boys on ponies behind it. The scene switches to the group turning the curve to head to the school and suddenly there are 2 wagon's now instead of one. There's the original one with the white pony and now there's a second one with a palimino pony with a Christmas tree in the back, followed by the 2 boys on horseback. Where was that cart in the beginning of the scene before they made the curve?
