This stacking tower by Yookidoo makes fun sounds and has lots of activities. The tower contains five colourful stacking blocks, each with a clicking or rattling sound. Your child can drop the three friendly rattling balls through the middle of the Stack Flap N Tumble, the soft crackling wings on the sides will then flap. The toy has two different openings, so it will remain a surprise for your child which opening the ball comes out of. The top stacking block is in the shape of a flower and has soft, crackling petals.
