Mouse, the rambunctious rodent first seen in Fleming's Lunch, returns in this concept-book salute to hands-on (or, in this case, paws-on) creativity. Beginning at the beginning—the letter A, of course—Mouse fashions letters by means of various arts and crafts. Fleming has embraced the broadest definition of "construction" to include such activities as sawing, gluing, buttoning, icing (as in a cake) and quilting. Young children will no doubt enjoy seeing Mouse scurry—sometimes humorously splattered with materials—from one letter to the next, although they may puzzle over a few of the scenes. A few of the entries strain to fit the overall theme—as when Mouse X-rays the X, Yanks the Y and Judges the J. The always playful, exuberant mood of Fleming's handmade-paper artwork, however, remains intact. Her broad range of dynamic, intense colors envelops readers with its sunny warmth. Ages 2-5. (Aug.)
