A young princess and the admiral of her father's navy are in love, but an evil sorcerer separates them while trying to take over the kingdom using dark magic from the titular crystal.
Examples
- Animal Motif: The grandfather's ship is called the Blue Heron.
- Big "NO!": Lord Warrick screams this as he tries to catch the Blood Crystal only for to be shattered in front of him, killing him.
- Bittersweet Ending: Lord Warrick has has been defeated after the Blood Crystal has been shattered (killing him). But unfortunately, the Admiral forever remains a heron, and the crystal was the only thing that could turn him back to human. The Admiral realizes this, knowing he and the Princess can never be together now and flies away. But not wanting to be without him, the Princess begged Renee to turn her back into an egret, knowing she won't ever become human again, and possibly never see her nanny, her father or her kingdom again. The movie ends with the two birds flying together (and helping lost ships).
- Court Mage: Lord Warrick. He was even referred to as the court wizard by the King.
- Eternal Love: The Admiral and the Princess.
- Evil Chancellor: Lord Warrick
- Forced Transformation:
- The Admiral was transformed into a heron as punishment for trying to assassinate the King (when actually Lord Warrick hypnotized him into doing so). Lord Warrick originally wanted him to turn into a vulture, but the King is against it due to the Admiral's faithful loyalty. Sadly, the Admiral remains trapped in this form due to the Blood Crystal, which would have turned him back to human, being destroyed.
- During the fight, Baggot got turned into a frog-like creature, which is permanent after the crystal was destroyed.
- Foreshadowing:
- A heron and an egret appear at the start of the movie. They fly off during a storm, to help guide the boy's grandfather to the lighthouse, back to his family.
- When Baggot accidentally knocks the Blood Crystal, Lord Warrick frantically caught it in time. We learn that he will die if it's destroyed.
- Frame-Up: Lord Warrick brainwashed the Admiral to kill the King, but hearing the Princess's voice broke the spell to due his love.
- Framing Device: The movie begins with a boy and his grandmother living in a lighthouse. The grandmother tries to make radio contact with her husband who's a sailor, during a terrible storm. The grandmother tells the boy the story while they wait out the storm.
- The Good King: The King
- The Igor: Baggot, the court jester who serves Lord Warrick.
- Magic A Is Magic A: Renee can't use her magic to change the Admiral back to human, apparently only the Blood Crystal can do it, but it was destroyed.
- Magical Nanny: Renee
- Maybe Magic, Maybe Mundane: The two birds who helped the boy's grandfather find his way home may or may not be the Admiral and the Princess.
- Missing Mom: The Princess's mother (and the King's wife), the Queen. Presumably passed away when the Princess was younger.
- My God, What Have I Done?: The King, for believing Lord Warrick's accusation of the admiral being a traitor.
- No Name Given: The Admiral, the Princess, the King, the boy and his grandparents.
- Ontological Inertia: The destruction of the Blood Crystal didn't change the Admiral back to human. Neither did Baggot.
- Parental Substitute: Renee is like a mother to the Princess.
- Redshirt Army: When the King returned, he had his soldiers seize Lord Warrick, but he zapped them with his crystal, making them disappear. But it's unclear if he killed them or teleported them somewhere else.
- Royals Who Actually Do Something: The Princess and the King. The latter immediately sails to a neighboring kingdom with his army to help save them from invading barbarians (unaware they've been tricked by Lord Warrick); the former is aware of Warrick's schemes and tries to stop him herself.
- Soul Jar: The Blood Crystal. Lord Warrick's soul has bonded with it, destroying it kills him.
- Star-Crossed Lovers: The Admiral and the Princess, due to the former being unjustly transformed into a heron.
- The Usurper: Lord Warrick
- Vile Villain, Laughable Lackey: Lord Warrick and Baggot
- Wizard Duel: Between Renee and Lord Warrick.
