Now an animated series on Disney Junior! The Chicken Squad is back for their fourth (mis)adventure, and this time they're facing their darkest mystery yet: shadows! A "lip-bitingly funny" (School Library Journal) chapter book from the bestselling author of Click, Clack, Moo and Cyclone. There's a big, SHADOWY mystery lurking about on what was supposed to be a nice chicken-family vacation to a farm. Sugar is certain that she is being watched, and when Poppy's beloved shoe (the shoe that keeps her safe and snug) goes missing, Sugar is sure that this shadow is the culprit. But how does the Chicken Squad tackle a shadow? And do it without ruining the family reunion...which includes meeting eighty-five cousins whose names all begin with the letter B, a lesson on figuring out perimeters (no, Sugar, the perimeter of a car is not one mile), and deciding how many bags of jelly beans one should pack for a road trip?
