Each book holds the element of surprise, as Ryder presents an Adventure Bay mystery with a new clue on each spread, challenging young children to guess which hero PAW Patrol Pup saved the day! The suspense builds with every page turn, until the mystery Pup's identity is revealed at the end! Pages have die-cut, jigsaw puzzle-shaped cut-outs; one cut-out on the first page, two cut-outs on the second, etc. With each page turn, a new cut-out reveals a little more of the mystery Pup on the inside back cover. The cut-outs are placed so that the mystery character remains hidden, and the reader won't know who it is (unless he or she can guess from the clues) until the very last page is turned and all the die-cut puzzle shapes are fit together to reveal his or her identity in a scene on the inside back cover. 1st in a series of PAW Patrol Surprise titles
