A nicely rhymed text goes beyond the obvious ``Lions roar'' and ``Cows moo'' to include the likes of beavers, parrots, and even, as a refrain, ``girls and boys make a different noise!''- -with examples of their singing, chuckling, talking, etc. captioning Wellington's bold, simple, but effective illustrations. An attractive extension of an old idea. (Picture book. 1-4)
