This adorable, prehistoric pal helps get little ones crawling with super fun ball-popping action. The bat-at roller lets your baby start the action with eight silly tunes and sounds. Then, when your baby places the six colorful balls inside its belly, the musical dino starts popping them here, there, and everywhere—encouraging your tiny cruiser to crawl after the spilling balls! Where development comes into play Gross Motor: Chasing after the balls that spill out of this playful dino gets little bodies moving and helps build up little muscles along the way! Fine Motor: Grasping and placing the colorful balls in the dinos belly helps strengthen your little ones hand-eye coordination! Sensory: The playful music, bright colors & exciting popping actions stimulate and engage babys developing senses!
