When the lights go off, the PESTS come out! The laugh-out-loud new series from the author/illustrator of the bestselling DIARY OF PIG series. Meet Stix, the tiny but heroic mouse who might be living behind your washing machine. But is he naughty enough to join the PESTS? Stix is the size of an egg cup, can jump the width of a dog's bottom, and LOVES cheese. That's because Stix is a mouse. He probably lives behind your washing machine, but you wouldn't know it, because his grandma taught him to always stay out of trouble and NEVER let the humans know he's there. But now Stix has stumbled across PESTS - the Peewit Educatorium for Seriously Terrible Scoundrels - in the basement of his building, and along with a whole host of new pesty friends (and enemies), he's about to rip up Grandma's rule book and make a REAL pest of himself...
