Badgers were black and white creatures that dwelled all over Middle-earth. They were known in the north as being exellent hole-diggers. A mysterious and supposedly legendary race of Badgers, the Badger folk,featured in Hobbit verse and included in The Adventures of Tom Bombadil. The poem describes Tom being captured by one of these mysterious creatures, Badger-brock - leader of the Badger folk - and subsequently being released after he frightened them with one of his magical chants.
While passing through Moria Sam commented 'There must have been a ighty crowd of dwarves here at one time and every one of them busier than badgers for five hundred years to make all this, and most in hard rock too!''
