Usborne Slider Sound Book Moo

In this unique sound book, move the sliders back and forth to see and hear the farm animals come to life.
Move each slider and you'll see a farm animal and hear the sound it makes... but that's not all! Move the same slider back again and you'll see and hear a different animal. Children will love discovering all the surprises hiding in the sliders as the cows, pigs, sheep and hens get noisy on the farm.
