The Secret of the Old Chest

This time, the most ordinary Norwegian children, Martin and Matilda Syursen, are visiting their grandfather Oscar. Oscar is rightly called the Chocolate Grandfather, as he is a terrible sweet tooth and can't live without candies and chocolate. As always, with Chocolate Grandfather, the children are in for incredible adventures: they travel through time, meet real Vikings, and search for a stolen chest that holds a magical artifact capable of granting any wish, but only one. It is very important to find the chest on time, as it has fallen into the hands of the cunning Paulsen sisters, who hate sweets and dream of destroying them all over the world.

Will they succeed in their plans, or will Martin, Matilda, and Chocolate Grandfather manage to stop them in time?
