Kanga searches for the culprit behind her missing cookie dough in this easy-to-read rhyming book. As in the popular children’s chant, “Who took the cookie from the cookie jar?” Kanga searches through her neighborhood, asking various animals, from Lion to Zebra to Cheetah, until she discovers what happened to her cookie dough. The refrain, “Do you know / Who ate all the cookie dough?” repeats, building tension and interest, inviting the readers to solve the mystery themselves. Exaggerated, expressive watercolors draw the reader to the eyes of the various animals who end up congregating on the edge of the left-hand page as Kanga pursues her investigatioin. The ample white space, peppered with gentle background graphic elements and a clear typeface, couples with the child-sized mystery to make this a good offering for new readers looking for books to read independently. Even though the lift-the-flap surprise ending will no longer be one upon subsequent readings, the amusing illustrations of popular animals and the jaunty rhythm and rhyme will make this a favorite.
