Continuity mistake: Zelda slips her basket of fruit onto a branch of the tree she pulled down to fling it at the dragon. As she begins pushing down on the tree to give it more spring, one section of the leaves suddenly just vanishes towards the middle. And two other sections of leaves suddenly turn from dark green to light green. Then just before she releases the tree to act as the catapult, they quickly fade back to how they were with rapid rising opacity.
