In the British children's comic strip, what animal is Rupert Bear's friend Bill?

Rupert Bear is a British children's comic strip character and franchise created by British artist Mary Tourtel and first appearing in the "Daily Express" newspaper on 8 November 1920.

Rupert is a bear who lives with his parents in a house in Nutwood, a fictional idyllic English village. He is drawn wearing a red jumper and bright yellow checked trousers, with matching yellow scarf. Originally depicted as a brown bear, his colour soon changed to white to save on printing costs, though he remained brown on the covers of the annuals.

Bill Badger is one of Rupert's chums. He originally appeared in Rupert's first story and is so Rupert's oldest and longest chum. He can be considered as Rupert's best friend.

Bill, as one of Rupert's closest chums, always looks on the bright side. He shares many adventures, and is a long-standing pal Rupert relies on. Bill has a good sense of fun, and lives with his parents and baby brother in Nutwood.

Bill is shown to be a anthropomorphic Badger, wearing a blue jacket with a red/yellow waistcoat and white shirt under it, a big red bow tie, light gray (or purple) pants with stripes and dark blue shoes.
