Continuity mistake: As Lulu is racing up to the school, you see the brick base of the school house and that the bricks are a dark red color. It then cuts to a closer angle as she is about to pull her fishing pole out of the steps and suddenly the bricks are now a light grey. Also in the same shots, you see first that the tree's shadow is lay across the walkway in front of the steps. But in the close up the shadow is nowhere to be seen.
