Snow White in the Woods

Snow White's first experience in the woods is not a pleasant one, as her imagination, having just been spurred by the reveal that her own stepmother wants to kill her, causes the frightened princess to imagine the trees and surrounding plants as monsters, crocodiles and beasts out to get her. It is only after she's calmed down, that the wood turns more peaceful and the animals come to help her.
