Description: Tobble Tones offers an alternative to traditional rattles to create opportunities for play in different body positions or for children who can't hold onto a rattle to still participate in play. It is a triangle shape with a curved bottom so it can wobble back and forth when it's pushed or pulled. A plastic mallet inside plays two bell tones as it rocks. A transparent window on the front and back makes it possible to watch the mallet hit the bells. Can be used for play in a seated position or during tummy time
