Just spin the roller to bring this dinosaur to life with silly sounds, fun music and 2 levels of ball-jumping action. The excitement gets a-rollin’ and a-poppin’ when baby drops the balls through the dino’s back, tail or belly. Fun ball poppin’ action for your little one as the balls bounce up, down and all around, making fun sounds & tunes as they go. But where they’ll pop up, nobody knows! Your little wiggle worm will love crawling & chasing after the balls that pop out of the mouth, tail or belly – and doing it over & over (& over) again! Requires 3 C (LR14) Alkaline batteries.
