Zavvi - The Home of Pop CultureExamine all the probabilities of the day ahead while sipping your morning cuppa with this Fantastic Beasts Demiguise heat changing shaped mug, molded to perfectly resemble the mysterious Demiguise, the creature with the special power to see future events and turn invisible at a moment's notice. When cold, the mug which features hand painted and embossed details, has dark coloured eyes. However, when hot liquid is poured in, the eyes transform to flash blue. The mug returns to it's original state as it cools. A perfect gift for any fan of J.K. Rowling's Wizarding World and a must for any Fantastic Beasts display.
