The scene begins in Marinette's bedroom. The girl with blue hair is studying a little.
Her Ladybug Kwami looked preoccupied with something.
"How are you, Tikki? You haven't said a word during the evening."
"It's just today is Nooroo's 3400th birthday." Tikki explains to Marinette.
"Nooroo, the butterfly Kwami in Hawk Moth position?"
"Correct. We Kwami will be able to switch between us and seeing that we are together increases our luck."
"If it allows you to speak with Nooroo. I give you permission." She gives permission to her Kwami.
"Thank you, Marinette." Tikki takes a felt pen and flies to Master Fu's house.
The scene changes to Lincoln's bedroom. He and his Kwami eat the macaroni meatball.
Lincoln, today is Nooro's birthday. We the Kwami will try to talk to him on his 3400th birthday."
"The Butterfly Kwami? Him that Hawk Moth harnesses his powers for evil?"
"Right. This is our only chance to do it."
"It's been a week without a villain. Ok, you can go."
"Thank you, Lincoln, the Kwami inside the Miraculous Box will have the chance to eat your father's dish."
He takes his dumplings from the bowl and goes to Master Fu's house.
Tikki, As, Plagg and Sass intersect halfway. The four Kwami go to their master's house.
The scene changes to Gabriel Agreste's studio. He was working on a new creation,
Nooro takes the opportunity to try to slip away but is stopped by his carrier.
"Where are you trying to go like this, Nooroo?"
"Master, today is my birthday and I think..."
"Must you remember the rules? What if I forbid talking?"
Because of his words, Nooroo's mouth disappears.
"..."
Gabriel's Miraculous senses a negative emotion.
"Enough laughing. We have work to do.
Gabriel transforms into his villainous alter ego.
The scene changes to the house of the guardian of the Miraculous. The old man is sleeping.
Tikki, Plagg, As and Sass are greeted by Wayzz.
"Everyone is waiting for you inside." Wayzz tells them.
The four go inside while Wayzz shows guard in case a villain appears.
Above the Royal Wood. A small figure in navy blue color rides an ear. It flies over the city and responds to stardust everywhere.
The victims see their nightmare become a reality.
Flip is the first victim of the dust. A health inspector is in front of Flip and is holding a closure notice.
"My worst nightmare has come true! No!1"
The people of Royal Wood are their worst nightmare.
Sandboy flies over another house and makes other victims.
Other residents of Royal Wood live out their fear.
In the Loud house. They are living their worst nightmare.
Luna was trying to invent a new song.
When his idol Mick appears,
"Mick?!"
"Luna Loud you don't deserve to have your portal from me. I ban you from all my future concepts!"
"No!"
Lily also lives her nightmares. Giant flip and the scary tentacle monster Lily.
In his bedroom, Lincoln hears his terrified family. The white-haired boy sees his family living their bad dream.
"Who's going on here?" His pure deviance becomes a reality.
A horror movie monster appeared and chased Lincoln.
"Damn, As is with the other Kwami and at the master's. I don't know where he lives."
Leaving his house. Lincoln sees Sandboy flying over the houses.
"Here, Sandboy. You will experience your great fear." He goes further away.
The scene changes to the house of the guardian of the Miraculous.
"Tikki, are you there? Tikki?"
Inside the box. The Kwami try to antagonize Nooroo but the latter with his bearer.
Hawk Moth has a feeling that someone is trying to contract him telepathically.
"What is this? Someone is trying to contract Nooroo."
It reacts to communication to locate the source.
"Nooro is not answering."
Suddenly, they sense that Hawk Moth is trying to locate them.
"Hawk Moth is trying to find your Location. Quick everyone, cut the communication!"
The Kwami cut off communication to prevent the vlain from finding their whereabouts.
"Hawk Moth is active. Tikki, Plagg, As and Sass, you must join your carrier immediately."
"Yes."
The four Kwami come out of the box. Tikki finds Marinette and transforms into Ladybug.
Plagg, Sass and As leave to join their carrier.
Meanwhile, Ladybug Girl takes on Sandboy on her own.
"Sandboy! You know kids are supposed to sleep now?"
"No, it's up to you to sleep and live your nightmare."
Sandboy sends his dust on a ladybug girl.
His yoyo is unusable.
"I can't use my yoyo?!"
"Now you are going to give me your earrings."
Sandboy attempts to grab Ladybug's earrings but is pushed off by a blow from his stick.
"Who did that?"
"Me." Ace of King said.
"And U.S." Chat Noir and Viperion say.
"Akuma must be in his pillow." It is the only object in his possession.
"In that case, take him back."
The four heroes join forces to retrieve Sandboy's pillow.
Sandboy climbs higher to keep a distance and uses his power on Cat Noir."
"Chat Noir, I've never loved you. You're the worst teammate." The fake Ladybug says.
"Seriously? Is that your biggest fear?" Viperion asks.
"I'll Eliminate You All! Lucky Charm!" A huge sword appeared and the fake ladybug fought with this weapon in hand.
"Keep still, for I'll slice you in half!" The scythe Ladybug continues to attack them with her sword.
Ladybug uses her vision to get out of this situation. She explains her plan to her teammates,
"Seconde chance!"
The snake boy throws his lyre like a boomerang.
Ace of King and Cat Noir race against the scythe Ladybug to seize her army.
But fails during their attempt Viperion goes back in time a few seconds.
This time, King and Cat chose another strategy to act differently to regain the weapon.
The scythe Ladybug tries to focus but gets easily distracted.
And gets her sword stolen, Ladybug used to cut Sandboy's pillow.
Akuma is out, gets captured, and thanks to the Miraculous Ladybug.
The nightmares disappear. Cat brings the child home.
At Hawk Moth's lair.
"Another villain has been defeated. Normally I would be frustrated but thanks to the Kwami who tried to contact Nooroo, I can confirm that the guardian of the Miraculous is in Royal Wood. I will find him and force him to reveal the identity of the superheroes to me. of Royal Wood."
Hawk Moth has a new objective, to find the guardian.
