I remember a movie cartoon it had little fairys? And they lived near a little girl well it's winter and the one day the girl gets off the bus but doesn't go directly home and ends up getting lost in the woods. She passes out or gets sick and the fairy help her back home. On the way they seek shelter in a bear cave and have to find a way out and also there's a scene where they are in a home that seems to be in the trunk of the tree. That's all I remember if you have any suggestions I welcome all! Thank you!
