Deep in the jungles of Mystery Island lives a strange masked Yurble. Long ago, this Yurble was just a regular Neopet... until one day he stumbled upon some very odd coloured stone blocks in the ruins of Geraptiku. The Yurble discovered that when he arranged the blocks in 2x2 squares of the same colour, they would disappear. Unable to figure out what caused this phenomenon, the Yurble decided that the only possible answer was that he was a mighty witch-doctor. He donned the fearsome tiki mask he wears today and has been 'magically' crushing the coloured stone blocks ever since.

Fortunately, it’s not magic that makes the blocks disappear... not the Yurble’s magic anyway. Why not try flipping a few stone blocks yourself?
