Chocolate Grandfather. The Mystery of the Old Chest

In the Norwegian city of Bergen lives a quite ordinary family: mom, dad, six-year-old Martin, and his older sister Matilda. But everything changes, and life suddenly fills with exciting events when their grandfather Oscar comes to visit, whom the children have never seen before. Oscar is not called Chocolate Grandfather for nothing, as he is a terrible sweet tooth and cannot live without candies and chocolate. At first, Martin and Matilda have to fight against the mischief of the naughty Paulsen sisters, who dream of ruining the annual city sweet fair. Then they travel through time, meet Vikings, and search for a stolen chest that holds a magical artifact that grants wishes. For where Chocolate Grandfather is, there are always adventures and magic!
