Do cows sing? Do cows cuckoo? All I know is cows go . . . MOO Simple, rhythmic, and lots of fun, this big, brightly illustrated board book will have kids happily imitating all kinds of animal "talk." For each creature--including a sheep, duck, frog, and cat--a giant "mouth" flap lifts up to reveal a new animal sound that will surely inspire a symphony of baa-ing, ribbiting, and meowing. And, at the end, children can open two barnyard gates to see and say all the animal sounds again.
