Troll or Horse?
When Laura and her son get into the car, there is a red-haired troll doll on the dashboard. However, in one shot from outside and in front of the car, you can see that there is a toy horse in the troll's position.
Plow Tracks
While the plow man is about to plow the kid's snow fort, you can clearly see that the plow is following plow tracks that were already in front of the plow leading up to the fort. Perhaps they were practicing this scene before?
