Part of the Franchise/{{Barbie}} series of DirectToVideo films, this one tells the story of a girl lost in a shipwreck and raised by the animals on a tropical island. The girl suffers from amnesia, and the only clue to her past is an item with a fragment of her name, "Ro". When she's grown up, Prince Antonio finds the island, and after Ro saves his life, he offers to take her to his home, and she comes along to find out about her past.

One the way home, the two start to fall in love, but Antonio's father, Peter, arranged a marriage to Luciana, a princess of another kingdom. Unfortunately, that lady's mother, Ariana, is holding a grudge against Peter and his family, and is planning to murder them at the wedding.
!!Provides examples of:
* ArrangedMarriage: But neither the would-be bride or groom are happy about it.
* BlondeBrunetteRedhead: Rita, Gina, and Sofia, Peter and Danielle's young daughters.
* BrokenAesop: A source of conflict in the movie is that Ro and Antonio fall in love and want to marry but can't because Ro isn't of royal blood. Eventually they just say "screw it" and decide to marry anyway, giving the moral that it doesn't matter if two people are from differing social classes, they should be allowed to be together if they're in love. However, at the very end, it's revealed that Ro is the long-lost Princess Rosella of Paladia, meaning that she ''was'' royalty all along, which kind of cancels out the intended aesop.
* CoversAlwaysLie: Well sort of lie here. Ro's fancy dress is topped with her having {{long hair| is feminine}} and wearing a CoolCrown. In the movie, her head is bare and the hair is up in a fancier version of a PrimAndProperBun. She also doesn't wear the crown at one point in the film.
* DanceOfRomance: Played with, as that is when Antonio tells Ro that he loves her, but she says it can't work out.
* DiegeticSwitch: "I Need To Know" starts out with Ro singing to the animals in the first verse; from the second verse on, it's from the internal thoughts of Ro and Antonio.
* DrivenByEnvy: Tika hides a note Antonio wrote to Ro, although she's not exactly jealous, just worried that Ro will leave her.
* EverythingsBetterWithPrincesses: Luciana, the triplets, and Ro turns out to be Princess Rosella of Paladia (hence why the title calls her a princess).
* EvilRedhead: Ariana
* FairytaleWeddingDress: [[spoiler:Rosella wears one when she and Antonio marry.]]
* GracefulLadiesLikePurple: Luciana wears a purple dress.
* TheMusical
* NeverSayDie: Averted. [[spoiler: It's said at several points that the animals will starve to death if not given an antidote.]]
* NubileSavage
* PeacockGirl: The peacock tail on Ro's dress is from Azul's own tail feathers.
* PimpedOutDress: Loads, given much of the film takes place at a royal court. The standout dress is Ro's blue dress with the [[FluffyFashionFeathers peacock tail]].
* PrincessClassic: Ro, even when she just lives among her animal friends.
* PrincessesPreferPink: Ro's standout dress is mainly blue, but has a pink overskirt, and the peacock tail is mostly pink. TheMerch also adds a pink CoolCrown.
* ProperLady: Luciana
* {{Robinsonade}}: Ro grows up in this setting, but it's a much lighter form of the trope than typical.
* RuleOfGlamorous: No reason is given that the green part of Azul's tail feathers turn pink after Ro puts them on her dress (other than parts of the dress are pink). Or how Tika's trunk spray turns into {{sparkles}} on the dress.
* SpeaksFluentAnimal: Ro, although Ariana [[ExploitedTrope takes advantage of this in her scheme]].
* SpiritedYoungLady: Ro
* TrueBlueFemininity: Danielle's dress is blue on the overdress (with [[PinkMeansFeminine a pink petticoat]]), and Ro's standout dress is mostly light blue.
* VillainSong: Ariana sings about the scheming and murdering she did to eventually get revenge on the royal family.
