What type of animal was 'Biffo', who appeared on the front cover of the British comic 'The Beano' from 1948 until 1974?

Biffo the Bear is a fictional character who had his own comic strip in the British comic The Beano. Biffo is an anthropomorphic bear resembling Mickey Mouse who gained the front cover of the comic starting from issue 327, dated 24 January 1948, replacing Big Eggo.

Dudley D. Watkins drew Biffo from the character's debut in 1948 to his sudden death on 20 August 1969, after which David Sutherland replaced him. He remained on the front cover until issue 1677, dated 7 September 1974. Dennis the Menace took over as from the following week, and Biffo was relegated to the inside pages. In the late 1970s, Sutherland stopped drawing Biffo, and the strip was taken over by Jimmy Glen.

His strip was retired in the 1980s (with his final appearance coming in issue no 2310, dated 25 October 1986), by which time it had been reduced to a single line of four pictures. However, the strip came back in 1989 with the title shortened to just 'Biffo'. The format had been revamped to three or four frames over a page with no speech, often depicting Biffo in fantastical, surreal situations. These strips were mostly drawn by Sid Burgon, though Trevor Metcalfe contributed a few stories as well, including in the Beano Book 1994. In the Beano Book 1999 Milly O'Naire (from Milly O'Naire and Penny Less, from the IPC Jackpot comic) made a guest appearance as well as her dad. This was probably because Sid Burgon had previously drawn that strip as well.
