Today is Halloween at Royal Wood and the perfect party for Lucy Loud. Lucy leaves the house to admire her labyrinth.
"I am so happy. I'll finally put my terror skills into action. "Lucy said with a mouse.
Leni goes out in her English girl costume.
"You can remind me why I have to hide my head. "
"Your character has been beheaded."
Lori walks out in her vampire costume.
"I'm going to drink your blood."
"To make it more realistic, can Fang bite you? "Lucy suggests.
"No thanks. "
The whole Loud family is ready to lend a hand.
The scene begins in Royal Wood Elementary School.
Mylène is scared by the Halloween decorations.
"Ahhh!" Mylène runs to hide behind Marinette and Nikki.
"How are you Mylène? "Marinette asks.
"No! I hate Halloween. The decorations are so scary. "
"I take this as a compliment. "Lucy appears out of nowhere and scares the three girls.
"I hate Halloween! "
"Poor Mylène, Halloween is supposed to be fun. We have to help him endure his fear. "
"How? 'Or' What? "
"Call the others, I have an idea and Lucy you're going to help us. "
Nikki calls Lincoln, Clyde, Juleka, Adrien, Ivan, Nino and Lee.
It's night. There are a few seconds left before the candy hunt begins.
The group will help their classmates to overcome their fears.
The scene changes for Lincoln's house.
"Guys, this is really nice of you but I don't know if this is really a good idea."
"Everything is fine . Here, you can keep that as a lucky charm. " Ivan hands his badge to Mylène.
Mylène regains a little self-confidence and goes into Lucy's corn maze.
She enters the corn maze. Keep moving forward and find a witch.
Mylène cry of terror.
"Mylène, it's me Nikki. It's just a costume. It's not true."
"...OK. "Mylène continues to advance and falls on her friends in disguise.
Even if they are costumes. The girl with the braids is really scared and runs away.
"Mylène! "Ivan tries to catch Mylène but the girl is already far away.
She continues to run to De Flip station and is terrorized by the spooky Halloween decorations.
"I hate Halloween! "
At his lair, Hawk Moth senses the girl's negative emotions.
"Fear, an ideal source of negative emotion for my Akuma. Stuffing or Akuma. "
The black butterfly flies out of the window and joins Mylène, to be absorbed by her badge.
{Horrifica, I am Hawk Moth. You who have always been afraid, today I give you the power to frighten others. In return, you bring me the Miraculous from the heroes of Royal Wood.}
"I can't wait to feed on their fear."
She transforms into a pink-colored bipedal creature with three eyes and a tail.
The bipedal creature grunts.
"What was that?" Flip outside where he hears the growls and stumbles across the world. "Ahhh !"
His fear makes Horrificar grow taller who is now a little taller.
The bipedal creature encloses Flip in a cocoon. The beast heads for the vicinity of Royal Wood.
The children had gone out to collect the treats.
Chandler and his two friends run into Horrifica.
"Look at this costume." Chandler said.
"He looks so real."
"I wonder who is hiding inside? "
Chandler tries to remove the monster's face but quickly realizes it's not a costume.
"Ho oh!"
"Arrrgh !" Horrifica scares the three boys.
Further increases in size and encloses all three in the cocoon. Horrifica continues to scare all the candy hunters.
Meanwhile, at the Loud House Corn Maze. They are pensive.
"We should have done something less complicated. "Marinette said.
"You're right. Because of us, Mylène is even more afraid. "Ivan said.
"What do we do now? "
"..."
The group thinks about a solution to help their classmate.
Suddenly the group heard howls of terror from further away.
"Halloween night has started."
"They are already starting to get scared when they haven't visited Lucy's Corn Maze."
Horrifica comes towards them. The beast is behind Clyde and Ivan.
"Wow! This costume looks so real. You had to work hard to do it ... "Juleka said in touch but count that it was not a fake.
Horrifica lets out a terrifying roar that frightens the group. He disperses.
Marinette, Adrien and Lincoln search for a place to transform.
Horrifica terrifies everyone and locks people up in cocoons.
Lori, Rita, Lynn Senior, Clyde, Luna, Leni, Lola and Luan get locked in the cocoon.
"Now I hate Halloween even more. "Lynn Senior said inside the cocoon.
The bipedal beast has grown to three largest of its normal size.
She was going to go after Nikki but the Asian girl was saved by Ladybug's yoyo.
"Let me guess, are you vomica?"
The pink bipedal beast attacks the two superheroes.
"Go take shelter. "
The ladybug girl joins her two allies.
"Lucky Charme!" Its power causes a guitar string to appear. "A guitar string? How can I use this? "
"Do you plan to play a song? "Cat asks.
"A song that takes away fear. You know Loup qui stinks? "
"It will work. "
They sing the song of the stinking wolf. Horrifica begins to shrink as she doesn't feel the fear of her prey.
She gets small to the size of a mouse.
Horrifica goes and hides behind Ivan.
"This badge is the one I gave to Mylène." He recognizes the object.
Ladybug takes the object and breaks it. The black butterfly has come out and is captured by the ladybug girl.
"Miraculous Ladybug ! "
Millions of ladybugs rearrange everything. Everyone was released and enjoyed Halloween.
Mylène was still scared but was partying with her friends.
The next scene shows Lincoln and Ace in the Corn Maze.
"Your sister is really good," The White Kwami said.
"When it comes to spooking Halloween. "
Lucy scares her older brother with his fake chainsaw.
"Ahhh !"
Later in the night. Lee and Sass are in Lee's room.
"..."
"Do you still think about the bad guys that Hawk Moth created? "Sass asks his wearer.
"Yes, before he came. Royal Wood used to be a quiet town, but not anymore. "Lee said.
"Yes I understand. He does this to get the Ladybug and Cat Miraculous. "
"You never told me why they are important. "He asks out of curiosity.
"I can't give you all the details but say, with both of you can make a wish. "Sass can't say it all. "That's why the Snake and Rabbit Miraculous are here to prevent that. "
