From the Manufacturer:
Join Old MacDonald and his friendly barnyard friends as they help each other complete this classic childhood song. Pegs help children two and older easily grasp and manipulate the eight adorably illustrated pieces (farmer, cow, pig, horse, chickens, ducks, dog, and sheep). Match the pieces to the pictures on the beautifully carved and illustrated wooden puzzle board to hear Old MacDonald start the song ("Old MacDonald had a farm, E-I-E-I-O!"), and each animal complete its part (for example, the pig sings, "And on that farm he had a pig, E-I-E-I-O [. . . etc.]"). Directions and lyrics are included on the puzzle so kids can sing along!
