The Princess and the Pea is a ridiculous hodgepodge of stolen scenes and character designs hastily cobbled together into something resembling what someone could call a movie. Don't believe me? Here's the trailer to prove it:
Look at this! Look at this! Look at those shots! You've got Snow White and the Seven Dwarfs, Sleeping Beauty, The Hunchback of Notre Dame, Beauty and the Beast, The Fox and the Hound, The Black Cauldron of all things, and that's just in the trailer alone! How the people who made this never got sued, I have no idea.
Sebastion the talking bird reveals to the audience that this is actually a sequel to The Princess and the Pea, and not a retelling of the original tale, then continues to violate the rule of "show, don't tell"
Laird swaps out Heath's baby with his own, with no regard to the fact that they don't resemble one another in the slightest
Rollo goes from kingdom to kingdom looking for the perfect princess, but they're all bitches
Rollo runs into Daria in her secret place, and she tells him all about her esoteric "kingdom of the heart" in an incredibly creepy way that we're supposed to think is enchanting
Laird convinces the townsfolk to kill Daria. They nearly succeed after starting a forest fire. At the same time, Sebastian finally discovers the secret of the pea.
There isn't any.
Daria sleeps on the pea, but is too picky to handle the teensiest bit of imperfection. Sebastian then realizes that Daria is the true princess, only for Laird to come out of hiding and tie him up. But not kill him, because that would be smart. Sebastian and Fearless race to stop the wedding. The pigs expose Hildegard as an imposter, causing Heath to immediately disown the girl he's been raising for years. Laird takes Daria hostage, and flees with Helsa and Hildegard.
Rollo and the pigs pursue Laird through his secret passageway, and is about to trigger a trap when Daria warns him. Fearless then triggers all the booby traps, to Laird's dismay. Hildegard takes Daria while Laird prepares to kill Fearless. Rollo stops him, and Winthral chases Helsa. Rollo then once again lectures Laird about what nobility means, all things he knows. Laird then triggers one last trap to bury Rollo in rubble. But, Rollo is still alive. Rollo climbs to the top of the castle to find Hildegard with Daria, threatening to drop her off. Laird then knocks Rollo off the edge along with some of the railing, leaving him clinging for his life. Laird sends his falcon to finish him, only for Sebastian to stop him while wearing his grandfather's weird bird armor. Daria gets free, and knocks Laird into the moat. Hildegard grabs the axe and starts attacking, somehow sending Daria falling as well, before Rollo catches her. The pigs then come by and force Hildegard off the edge as well. It's a fall-off-the-edge party up in here! Fearless is a hero and gets the girl. Withral pulls Helsa out by the ham, and she is caught by guards.
Heath meets his biological daughter, and embraces her. One randomly magical transition later, she's wearing a crown and a wedding dress. She asks about her mother, and Heath agrees to tell her after the wedding. Heath gives Daria away, and she and Rollo prepare to say their vows.
