<p> Hilda Mae Heifer has lost her melodic <i>mi-mi-moo!</i> </p> <p> A klunk on the head and now Hilda's simply not sure what sound to make. </p> <p> Is it a mew, or an oink, or possibly a honk? With the eager help of the farm animals, Hilda is determined, once again, to sing her sensational moo. Which should most certainly be a <i>MOO-MOOO-MOO-MOO.</i> </p> <p> <i>Moo Who?</i> is a raucous read-aloud for the youngest noisemakers. </p>
