Professor Bramble
What they look like
A rusty orange fox with round golden spectacles and a little green cardigan with the elbows worn out from leaning on books. His tail is enormous and fluffy and he uses it as a bookmark.
What makes them special
He is the librarian of a secret library where the books whisper their own stories to you, and he actually knows the Dewey Decimal number of every book in the whole world by heart.
