Lava Ball

You've experienced the gravity-defying power of the Waboba Ball, now comes the erupting, colour-changing Lava Ball.
When you take the Lava Ball outside, its black surface bursts into colour, with cracks that change colour in the UV rays of the sun.
Like the original Waboba Ball, it has incredible bounce, so you can have endless fun, even after the sun has gone down.
