WereBears were a concept by my design partner George Nicholas, and I worked on the format and wrote scripts for the monthly WereBears comic, which was published by London Editions Magazines. We sold the toy rights for the WereBears characters to Hornby Toys who produced the four main characters, Howler, Grizzler, Gums and Fang.
The plush toys of the WereBears had heads and hands that could be turned inside out to show claws, teeth and fierce expressions.
A fifth WereBear, Growler, was added who had a voicebox built in. Hornby also produced the WereBears' enemies, the Terror Teds - Snapper, Munch, Chomp and Grunt. All the WereBear toys came with a cassette tape with an audio adventure on it; I wrote the scripts and oversaw their recording. Oliver Postgate (Clangers, Bagpuss) was the narrator, with guest voice artistes.
George and I are thinking of updating the WereBears concept, so watch this space...
