''Barbie: The Pearl Princess'' is a DirectToDVD Franchise/{{Barbie}} movie released in March 2014, though it had gotten a limited theatrical release in some theaters. In the Barbie filmography, it is preceded by ''WesternAnimation/BarbieAndHerSistersInAPonyTale'' and followed by ''WesternAnimation/BarbieAndTheSecretDoor''.

Barbie stars as Lumina, a mermaid girl with the power to [[HeartIsAnAwesomePower manipulate pearls]] with her mind. While she's rarely ventured outside her secluded home, Lumina has always wanted to, and soon finds herself working in a mermaid salon customizing fabulous hairstyles. When Lumina gets the chance to dance at the royal ball, it seems her dreams will come true--until the evil Caligo blackmails her adopted mother, Scylla, into poisoning the king and helping him claim the throne. Lumina and her friends must work together to stop him, and her pearl powers may prove key to saving everyone.

!!This movie contains examples of:
* AbusiveParents: Caligo doesn’t bother raising his son’s self-confidence nor respecting his dream career as a botanist. All he cared is putting Fergis on the throne and killing the royals in charge.
* AnimationBump: The shots of a furious Lumina during the final battle are much more fluid than any other angry expression shown in past films.
* AntiVillain:
** Scylla, a reformed witch who's forced into being evil.
** Also Fergis, who has no interest in his father's ambitions and wants to be a botanist.
* TheAtoner: Scylla wishes to reform for her evil deeds and raised Lumina rather than kill her.
* AwardBaitSong: "Light Up The World."
* AwesomeMomentOfCrowning: Not quite, seemed the ball announcing who is the heir apparent. It seemed the ball is celebrating the Crown Prince Fergis. In the end, it's Lumina's coronation as Crown Princess.
* BadassFingerSnap: Used several times by Lumina when commanding the pearls.
* BagOfKidnapping: The eels use a literal bag to capture Lumina and Kuda.
* BenevolentBoss: Madame Ruckus runs the Salon de Mer and treats her employees well, surprising them with tickets to the ball and [[spoiler:defending Lumina from the guards while she tries to save her aunt]].
* BigBad: Caligo, who leads the Trident Squad and a gang of eels.
* BondVillainStupidity: Caligo imprisoned Lumina, not once thinking of the RoyaltySuperpower could help break her out. He really should have kill or knock her unconscious for his plan to work.
* CallingTheOldManOut: After some confidence boost, Fergis bluntly told his dad he wanted to be a botanist to his face and shutting his mouth with his plant.
* ChekhovsHobby: Fergis wants to be a botanist, and it's this interest that helps him save Scylla when [[spoiler:she's poisoned and needs an antidote]].
* DamselOutOfDistress: Lumina and Kuda are kidnapped by Caligo and the eels. Once imprisoned, Lumina uses a supply of pearls to trick the eels into fighting each other, grabs the key, and escapes on her own.

* DeathGlare: Lumina [[http://i.imgur.com/8cTVSsD.jpg gives]] [[http://i.imgur.com/CgfHT3R.jpg one]] to Caligo after he [[spoiler:poisons Scylla]].
* TheDragon: Murray the eel is this to Caligo; he does a lot of the grunt work since Caligo is often at the palace.
* EvilPrince: Caligo wants Fergis to be this, but it's averted since he has no interest in ruling the kingdom or his father's ambitions.
** Caligo himself may count, as he is either Queen Lorelei's brother or the husband of King Nereus' sister. Either way, he would have some kind of royal title.
* FashionShopFashionShow: Lumina and her friends buy ballgowns and have a fashion show, set to the song "Mermaid Party!"
* {{Expy}}: Caligo is actually a combination of [[WesternAnimation/BarbieAsTheIslandPrincess Ariana]] and [[WesternAnimation/BarbiePrincessCharmSchool Dame Devin]] especially the former's wishing to forcing her children to marry the prince, poisoning people and taking over the kingdom while the latter's teaching students, murdering the protagonist's family and making her daughter to become royalty.

* HeartIsAnAwesomePower: Lumina makes good use of her pearls in combat.
* IAmWho: Lumina had no idea she was royalty.
* JockDadNerdSon: Downplayed. Fergis is a stereotypical nerd with the way how his character comes off while his dad is muscular in comparison. However, his dad doesn't even do his own dirty work, relying on manipulation and his own status as a possible royal to help him.
* TheMasquerade: Lumina was raised to avoid using her pearl powers in public for fear of danger.

** In contrast, Caligo's name is Latin for "darkness" or "fog."

* MotherMakesYouKing: Gender-inverted with Caligo and Fergis. It seemed after the princess, Fergis is next in the line for the throne.

* PimpedOutDress: Lumina gets a multicolored tail.
* PoisonedChaliceSwitcheroo: Caligo has ordered Scylla to poison the king's glass, but his and the king's cups are switched. He resolves it by spilling the king's glass and offers his own.
* PoisonousPerson: Spike the stonefish. Lumina helps him by using pearls to cover his spikes.
* PunnyName: Murray the eel, a pun on moray eel.
* RagsToRoyalty: A Sleeping Beauty example. Scilla was forced to murder Lumina as a baby by Caligo, but she had a change of heart and secretly raised her.

* ReligiousAndMythologicalThemeNaming: Caligo is named after the Greek mother of Chaos, and Scylla is named after the sea goddess from the Odyssey.
* ReusedCharacterDesign: Several fish were recycled from ''WesternAnimation/BarbieInAMermaidTale'' and ''WesternAnimation/BarbieInAMermaidTale2'', though with different coloring.
* RoyalBlood: Lumina, much to her surprise. Caligo and Fergis have to be this since the king and queen didn't put up much a fight, announcing who is to be the next ruler.
* RoyaltySuperpower: Lumina's pearl powers.
* SceneryPorn: Even in the teaser, the underwater shots are beautiful, and in the movie they're even ''more'' beautiful.
* SheCleansUpNicely: A male version with Fergis, who becomes more handsome after Lumina fixes his hair.
* TranquilFury: Lumina enters this state after [[spoiler:Scylla is poisoned]]. She gives Caligo a DeathGlare and focuses on taking him down.
* TransformationSequence: Lumina has one when she is given the Pearl of the Sea and is revealed to be the missing princess.
