And to make matters worse, his clumsiness shatters the Crystal and they lose the Great Book of Magic which flies off after the failed spell.

Now they return to life on the road with a new quest and adventure which is to reclaim the book and use it to find a way to repair the Crystal and finally break the princess' altered curse.
