It's the summer holidays and Rover is busy searching for poo. He works for The Gigglers, small furry creatures who make sure grown-ups are nice to their kids. If they aren't, they get the Giggler Treatment - a smelly, squishy present on the end of their shoe, which is where Rover comes in.But Rover and his nephew Messi (who is actually very tidy) are distracted from their job by a Big Fat Baby (B.F.B) who's fallen out of her Granny's backpack. It's time for Rover to find the B.F.B, even if it means chasing a postie all over the city, following an aeroplane to Casablanca and leaving the Gigglers with a poo shortage . . .The fourth title in the madly funny Giggler series and illustrated throughout by Chris Judge, this is Booker Prize-winning Roddy Doyle at his hilarious, brilliant best.
