The Chicken Squad is back for their third (mis)adventure, this time facing off with whatever’s hiding in a mystery box in the backyard. A hilarious chapter book in what has been called “a lip-bitingly funny series” (School Library Journal) by the bestselling author of Click, Clack, Moo and Diary of a Worm.

Our fluffy, fearless young detectives are back. There’s a new cage in the yard, and the Chicken Squad is determined to figure out just who this is in it. Because whatever it is, it’s definitely up to no good. Equipped with the latest surveillance gear—which apparently includes copious amounts of marshmallows—the chicks venture into the wild to get answers. Let’s just hope they can beat that giant raincloud that’s closing in…because everyone knows that chickens can’t swim!
