This is the set of toy stepping stones with integrated xylophone keys that play musical notes when jumped on by a child. Stepping atop each of the five platforms generates a different note, providing options for minor composers to create custom ballads or play simple tunes such as “Jingle Bells” or “Twinkle, Twinkle, Little Star”. The stones can be placed on the floor for a game of "the floor is lava" or set up on a table for creative play. Ideal for helping introduce children to music and develop balance and coordination, the stones can also stack atop one another for compact storage. Ages 3 and up. Each stone 8 1/2" L x 8 1/2" W x 2 3/4" H.
