I love the story/movie spirited away. But umm... you know how when Chihiro was little and she fell into the river, i know that haku saved her, but did he save her in dragon form or did he save her like with the water? Help me please=)
I dont think that he saved her in dragon form, or else Chihiro would for sure remember that. I think he used his river spirit powers or something to save her. Maybe to calm the water down? Or taking her back to shore through a wave. And I agree with Okami_Amaterasu on the whole how to become a river spirit :)
Okay I think I can help you out. If you remember when flying with Haku in the sky Chihiro said when she dropped her shoe in the river and fell in the water carried her back to shore. If you have the movie on hand or if you find it online she says that when they are flying in the air after leaving Zeniba's.
