The wheels on the bus go 'round and 'roun.. and kids will play with this puzzle over and over. Lift the six pieces of the school bus to reveal different pictures underneath that show what's happening and to hear the different verses of the classic children's song. Sing along as the wipers go, "swish, swish, swish," the horn goes, "beep, beep, beep," and more. The lyrics are on the back of the sturdy wooden resting board to help kids learn the words. Shaped wooden pieces with durable plastic pegs are easy for small hands to grasp, making this a perfect preschool puzzle.
