However, his confidence is low because he is bullied by his age mates, including royal princess Irene, because of his power of making unliving objects talk.
Adding to Dor's chagrin is his onsetting puberty, which makes him aware of his nanny Millie, a former ghost for 800 years who is in love with a zombie named Jonathan.
After striking a deal with the Brain Coral to safeguard his body during his trip, Dor casts his consciousness into the past via Magician Humfrey's magic and a decorative wall tapestry inside Castle Roogna.
Together they travel to Castle Roogna, which is still under construction in that era and is about to be caught in the midst of a massive battle between a horde of goblins and a flock of harpies, and—indirectly—by the magician Murphy.
With great effort, Dor's inventive use of his magical gift, and the use of a powerful forget spell, they are eventually able to defeat their monstrous assailants and even resolve the cause for the conflict between the two species.
