en Cuevana 3. A black crystal fell from space thousands of years ago and landed in the desert of the eastern Zahambra. Anyone who gets their hands on this meteorite can make a 'bad copy' of anything. A very dangerous stone, but luckily no one knows where the Black Crystal is hidden.... until criminal Axel finds it. In a nerve-racking race, Mieke, Toby and the others try to get it out of his hands. Will our friends manage to destroy the dangerous stone in time? What if they don't succeed and Mega Mindy has to deal with an evil copy of herself?
