When a poor miller can't give the King any money, he tells him that his daughter, Sissi, can spin straw into gold! At the palace, a devilish little troll magically appears and spins a room full of glittering gold for Sissi. But, in return, Sissi must give the troll her baby unless she can guess his name.
Along come Yoyo and Doc Croc to help Sissi discover the evil troll's strange name. There isn't much time and there are so many names to choose from, but with Yoyo and Doc Croc on the case you can be sure they'll come to the rescue.
This book accompanies the enchanting and hugely successful animated television series 'Simsala Grimm'.
