Mèche Blanche, les aventures du petit castor (2008)

Young beaver White Forelock grows up with mother and sister after their father was devoured by wolves. After a bear's weight causes a large gap in the dam, he's dragged away by the torrent. He meets and befriends a grumpy old beaver, the save each-other's lives from attacking wolves. Later they wander back to mother's lake just when White Tuft's mother and sister are fighting off an attack by an otter.
