Where's Tumpty?

Polly Dunbar is a much lauded author-illustrator, whose works - as well as the soon-to-be-televised Tilly and Friends series - include Penguin (9781844280650), Dog Blue (9781844285143) and Flyaway Katie (9781844285174). Polly thinks that colour is a brilliant way to cheer yourself up and whenever she's feeling grey, she puts on her best pink frock and paints. Polly lives and works in Brighton, Sussex. www.pollydunbar.com
