With just one more good deed to do, Princess Pulverizer’s Quest of Kindness is almost complete. But when she discovers that a fierce pirate named Cap'n Bobbie has captured a beautiful mermaid, she disobeys her father’s strict rule not to go beyond the sea and stays onboard The Seasick Soaker, vowing to free the gentle creature–even if it means losing her chance to become a knight. Can Princess Pulverizer and her pals rescue the mermaid and escape the pirate’s clutches, or are they doomed to walk the plank?
