That Pesky Rat: A street rat from birth, Pesky is looking for nothing more than a home and someone to care for him. Photograph: PR

Charlie and Lola: Charlie (seven) and Lola (four, nearly five) are brother and sister and go everywhere together. Lola's the boss, but loves Charlie above all others (apart from her imaginary friend Soren Lorensen, also in this picture). Photograph: PR

Herb: Herb fell into a book. The book, like all good storybooks, was full of excitement and danger. The danger came in the form of the devious Storybook Wolves. Photograph: PR

Clarice Bean: Clarice knows that adults don't always know best. She's learnt this from her fictional hero, Ruby Redfort, a detective and expert code cracker who's wise to government secrets. Photograph: PR

Hubert Horatio Bartle Bobton-Trent: Hubert's parents are rampant socialisers unfamiliar with the idea of paying bills. It's left to Hubert to sort out their financial mess. It's lucky he's a child genius. Photograph: PR

The Princess: Lauren's Princess is rather more down-to-earth than the precious girl in The Princess and The Pea that she's based on. She knows that real princesses don't grow on trees. Photograph: PR
