Filbur Apse was a particularly obnoxious person, who enjoyed upsetting and annoying anyone and everyone he came into contact with. One day, however, he went too far, annoying a seemingly harmless old man who turned out to be a wizard in disguise. As a punishment the wizard cast a spell which changed Filbur so that he was no longer obnoxious - and took all the fun out of his life! Can he find the magic ingredients that will make him thoroughly detestable once more?
