Suddenly, Scylla comes and Lumina disbands the party and hides the pearls she used in the oysters she got them from. Unfortunately, one oyster snaps shut too quickly, leaving a pearl out. Lumina tries to put it back inside the oyster without Scylla noticing, but Scylla does notice. She scolds Lumina for using her pearl magic outside because "bad people" might look for her, but Lumina argues, asking who could find her, unaware that Scylla is afraid Caligo would find out about her.
In the cave, Lumina and Kuda continue their fake coronation 由 customizing their hairstyles to look like princesses. They wonder what would it be like if they were princesses and dream to see the castle. Scylla hears their conversation, and hides a bracelet with the royal crest on it in a drawer.
In the castle, Caligo pleads with King Nereus and 皇后乐队 Lorelei to appear in public. Nereus starts to tell Caligo that he and his wife are still grieving over their 迷失 daughter. Caligo says that they have to face the fact that without an heir, their kingdom will one 日 go to his son, Fergis. Lorelei concedes that Caligo is right, and they should name Fergis their heir. Caligo suggests they give a royal ball to find Fergis a wife, to which the king and 皇后乐队 agree.
Back at the cave, when Scylla is making a potion, an 鳗鱼 named Murray comes. He tells Scylla that Caligo wants her to poison the king at the royal ball. Scylla refuses, but Murray threatens to tell everyone she killed the princess. Scylla 回复 "if it's poison Caligo wants, it's poison he'll get." Murray takes this to mean she has agreed, and gives Scylla an invitation to the ball.
Lumina swims in and overhears Murray talk about the castle. Murray hears Lumina call Scylla "aunt," and when Murray starts to ask for 更多 information, Scylla throws him out.
Lumina's excitement about the 城堡 isn't over. She asks Scylla to take her with her to the castle. Scylla says no, telling Lumina about "burning 火, 消防 coral and vampire squid and poisonous stonefish" as dangers on the way.
Disappointed, Kuda and Lumina start playing tail tag. Kuda accidentally knocks one of the bottles during the game. When Lumina goes to pick it up, she sees the invitation to the royal ball. She tries to give it to her aunt, but Scylla has already gone. Lumina sees this as an opportunity to go to the castle, and although Kuda reminds her of the threats Scylla told her about and hesitates to go, Lumina pushes her to 加入 her.
Lumina has noticed that every time Scylla goes to the city, she always comes from a shortcut, which then appears as a dead end. Her intuition takes lead, and not long after, she finds a passage through the skeleton of a big animal. While in the passage, Kuda accidentally breaks the structure and it collapses. They manage to escape, but the invitation is 迷失 to a narwhal.
Back at the castle, Caligo and Fergis are arguing. Fergis doesn't want to go to the ball since he wants to be a botanist rather than king, but Caligo tells him he is "going to be king and that's the end of it," after which Fergis leaves sadly for his waltz lessons.
Right after, Murray appears and informs Caligo that Scylla agreed to the plan. Caligo then reveals he plans to kill Scylla after the king dies of poisoning so he would be hailed as a national hero. However, Caligo has one concern: his son, who is not very eligible, will need to find a wife. Murray brings up Scylla's niece as an option, which raises Caligo's suspicions. Murray mentions the niece as "blonde, about seventeen years old" and that it is an "interesting coincidence." Caligo asks Murray to bring the girl to him.
Lumina and Kuda, in the other side of the ocean, are 迷失 in the middle of a kelp forest. Then they see the narwhal which took their invitation, only to lose it again. In desperation, Lumina sees light in the distance and rushes to it,believing it is the city, but it is actually a vampire squid lair. The narwhal goes in and most of the squid leave and chase it, after which Lumina and Kuda enter.
Once inside, they find a cute baby squid and admire it until the squid bites Kuda on the snout. Lumina manages to pull it off, but she falls onto a rock. When Kuda swims 由 the rock, it opens an eye. Kuda thus warns Lumina to 移动 away from it, but Lumina doesn't know why and accidentally slaps it with her tail, causing the "rock" to open its eyes and roar. It is revealed to be a stonefish.
The stonefish tries to scare Lumina and Kuda away 由 roaring and mentioning how poisonous his spikes are. Lumina uses her pearl powers to to put pearls on his spikes, and tells him that now no one will be scared of him. After 更多 coaxing, the stonefish agrees to accompany them to the city and practice making 老友记 with other fish. He introduces himself as Spike.
Back at Lumina's home, Murray appears with his sidekicks, Garth and Wormwood. Upon 阅读 a letter Lumina left for Scylla, Murray realizes she isn't home, but roots through Scylla's things anyway. He finds the bracelet Scylla hid earlier.
Back in the kelp forest, Lumina and Kuda are laughing at one of Spike's jokes when Kuda is caught 由 snarly kelp. Lumina removes a pearl from one of Spike's spikes, and he cuts the kelp with it, setting Kuda free. Kuda moans that she doesn't think they will make it to the city, but Lumina shows her they are already there.
In the city, Spike starts hiding, but Lumina tells him he shouldn't. Spike, afraid of being feared, comes out anyway, and a few merpeople compliment his pearls.
Then, Kuda sees Scylla in the distance. Lumina wants to explain that they were trying to bring her her invitation, but Kuda is worried and pulls Lumina into Salon La Mer to hide.
At first, Lumina is mistakenly thought as a customer 由 Madame Ruckus, but when she notices Scylla is passing by, she disguises herself 由 changing her hair and the same goes for Kuda. Madame Ruckus sees her talent and hires her alongside with two other employees, Sandrine and Cora. While Lumina is busy, back at the 城堡 General Caligo's plan is arranged he depends on Scylla to make the poison. His plan is simple, let Scylla poison the merberry nectar in Nereus' goblet, then he'll get the upper hand.
At Salon La Mer, Lumina has just become the most famous hairstyler in the city. Sandrine tries to keep up, but finally befriends Lumina despite her cruel behavior before.
Murray returns from his back-and-forth trip and tells Caligo he found no one, but he shows the royal crest to Caligo and confirms she is the princess. Caligo goes furious, as that could ruin his plan.
Again at Salon La Mer, Prince Delphin who has just come into the city is wrongly thought as an employee. He carries some things and delivers them to Lumina. He quickly bumps into her. Later, General Caligo takes Fergis to Salon La Mer for hairstyling. Although he's been searching for the 迷失 princess, unknowingly, he asks Lumina to do the job. Fergis instead, has fallen in 爱情 with Cora.
Later, Madame Ruckus comes to inform her employees that she got an invitation to the royal ball. Interestingly, they get anxious on what to wear, but Madame Ruckus winks at them. Then they go to a 商店 to buy some proper clothes. The 商店 is so crowded, that people just ramsack every single piece of clothing. So they decide to make them.
The scene skips to the royal ball, where Fergis calls upon Cora. His father interferes, then takes off his Quidest Fetere 花 saying that it smelled bad, then flaps his back. Cora and Fergis grow closer after Cora states she loves his flower.
When Lumina notices the narwhal who took her invitation, General Caligo gets flapped 由 Lumina's tail, but he welcomes her instead, saying he likes how she reorganized his son's hair. But, moments later, Murray tells him that Lumina is the 迷失 princess. Meanwhile, Lumina gets a dance with Prince Delphin and chat together. Then Prince Delphin says he needs to go for a while, and makes Lumina promise to save the 下一个 dance for him.
Caligo takes no time to waste, he immediately drives Lumina outside the ball, and captures her and Kuda with the help of the eels. Then they throw her into the dungeon. Lumina recognizes the 鳗鱼 as her aunt's friend. Murray tells her the truth; her aunt will poison the king. Lumina's creative mind lets her steal the key from the eels and tie them together. Then she frees herself and Kuda.
At the ball, Scylla has switched Caligo's and Nereus' goblets. Caligo knows this, but he realizes he has to face a new a dilemma; If Nereus drinks the real nectar, and he drinks the poison, he will be the one to die. His dilemma increases, when he has to decide which one is the poison: his 或者 Nereus's.
Then, Nereus coronates Fergis as the heir to the throne, and is about to have a toast. But, Caligo decides quickly to spill Nereus' goblet and offers him his. Scylla tries to spill it, but is blocked 由 a Trident. Lumina arrives in time to spill the goblet before Nereus drinks it, causing the gasp in the crowds.
Despite his plan having been ruined, Caligo refuses to give up. He states Lumina is trying to attack Nereus and tells the Tridents to arrest her. Scylla testimates, saying Lumina has just saved Nereusl, but before she has the chance to say what Caligo made her do, Caligo makes an effort to kill the witness and push her to one opened end of Spike. The venom of the stonefish is about to kill Scylla, but before she dies, she tells Lumina she took her from her parents to protect her.
Spike reveals which the antidote for the venom is and it turns out to be Fergis's Quidest Fetere. But before Fergis can say he has it, Caligo hushes him. Fergis decides to do the right thing, so he defies his father and gives Lumina the flower.
Caligo makes one last effort in the last minute, he takes Scylla's body intending leave. Lumina gets furious; she chases Caligo before he leaves the ballroom, but one of the Tridents grabs her tail. All of Lumina's 老友记 help defeat the Trident Squad.
Before Caligo reaches the gate, Lumina sends her pearls to the gate, locks it and uses all the pearls in the ballroom to ensnare him. Lumina gives the antidote to Scylla ,and it saves her.
Scylla states Caligo is the one who ordered her to poison Nereus and reveals Lumina is the long 迷失 daughter of Nereus and Lorelei.
She reveals the story: years ago, Caligo sought to be the king of Seagundia, and paid Scylla to poison the newly born baby of Lorelei, the true heir of Seagundia. She couldn't do it, but instead, she kept the baby with her, and told Caligo she was dead. As the child grew, she could have 给 it back to her rightful parents, but she couldn't do it, and she felt guilty for that.
Fergis returns the Pearl of the Sea back to the Nereus and he gives it to Lumina. Scylla gains her forgiveness and they stay together in Seagundia. The ball continues, and everyone lives happily ever after, except for Caligo that was pushed 由 Madame Ruckus out of the 城堡 and his fate is unknown.
