Binky is forlorn because the other Pocket Dragons don't have time to play with her. To help her, the Wizard casts a spell that creates a magical duplicate of Binky to keep her company. Unfortunately, unknown to the Wizard, the spell also creates a second, evil duplicate! The Pocket Dragons must find Binky's evil twin and reverse the spell before "Minky" can do any real harm.
