These are the award-winning blocks that can be rearranged to play a million different melodies, teaching children about music, shapes, and colors. A recipient of the Oppenheim Toy Portfolio Blue Chip Classic Award, it consists of five blocks that can be placed in any order into the sturdy base. Each side of each block plays a different phrase of music when pressed, while hitting the big red button on the front runs through all five phrases in sequence. A flip of a switch changes the music from a classical, symphonic performance to swinging jazz to drum-filled African rhythms. The volume is adjustable, and each block is a different primary color, with different shapes on each side to teach toddlers these basics. Includes four AA batteries. Ages 2 and up. 12 1/2" L x 7 1/2" W x 4" D. (2 1/2 lbs.)
