Mr. and Mrs. Beaver

Mr. and Mrs. Beaver are Talking Beavers from the Chronicles of Narnia book 'The Lion, The Witch and the Wardrobe'. They shelter the four Pevensie children and lead Peter, Susan and Lucy to the Narnian army and the Stone Table once it becomes clear that Edmund has run to the White Witch. They are known to be friends with Mr. Tumnus.

The Beavers' dam on the Great River is presumably the future site of the town of Beaversdam.
