Frog is lost, looking for his dad. But his dad doesn`t roar, does he? Maybe he whoops or squawks or growls instead? Find out in this hilarious changing faces book. Small children love to read books about animals & to see animal characteristics displayed through their sounds & expressions. This title in the Little Faces series of four books combines the two brilliantly with a venetian window device that allows the reader to have fun imitating different actions while getting ready for bed.
