When Tack upsets Zigzag the Vizier, the wizard drags him off to the royal castle, where Princess Yum Yum falls for the bashful boy and saves him from execution. Unfortunately, Zigzag plans to marry the princess in order to succeed her father, King Nod. The Thief, meanwhile, is more interested in gold than love and takes off with the protective orbs topping the palace. Together Tack and Yum Yum attempt to retrieve them in order to prevent Zigzag and the One-Eye army from conquering the city.
