Lucy is in the cemetery with the members of her club.
"I have an important announcement to say." Bertrand announces: "My father got a promotion and we have to move. I have no choice but to choose a new president. "
"Fang, this is my chance. If I can be president. I've always dreamed. "Lucy said to her bat.
"I have decided to appoint Haiku as my successor." Bertrand announces.
"I am so happy. "Haiku announces.
"Wait, I'm going to introduce myself as club president." Lucy offers herself as president.
"In that case we will vote or I will move this. The principal has offered to use the school mascot for the funeral home. The one who does the best funeral will be the next president."
"It's fine." Lucy says.
"Me too." Haiku said.
The two girls agree to the conditions. The next morning. The gothic girl goes to work.
Lucy goes to see her older brother to ask for help.
"Lincoln, I need you to help me with Ricky's funeral, the rooster."
"Ahhh !" Lucy startles Lincoln and his Kwami with fear. "Lucy doesn't scare us like that."
"We?"
"I mean I'm not scary like that."
"Sorry, Lincoln, but I want you to help me organize Ricky's funeral."
"Are you sure I'm adequate? I have no experience in this field compared to you who have been doing this for 3 years. "
"You are going to be fine. I'll tell you the directions. "
"OK."
Lucy comes out of Lincoln's room. As comes out of his hiding place.
"Your sister is really weird and it's used to appearing like that, it's really scary. "The White Kwami said.
The next morning at school. Lincoln helps Lucy organize the Ricky the Rooster funeral.
The whole school is assembled on the stands of the football field.
"Everything is perfect. I'm going to be the next president of the Morticians club. " She declares.
The members of the Morticians club go to see Lucy and they are not happy.
"Lucy, can you explain that?"
"Explain why?" It shows the contents of the box. Chicken croquettes.
Lucy goes to see Lincoln at the food stand.
"Lincoln, are you crazy? Why did you serve chicken nuggets at Ricky's funeral? "
"Sorry, that was the only food available. And I don't see the problem?"
"Lincoln, I have to remind you that Ricky is a rooster. Didn't you think that would be offensive? "The gothic girl points out to her big brother.
"Ohhhh! I understand better why As told me it was a new idea. " Lincoln realizes his mistake.
"At least nothing worse can happen. "Said Lucy.
And yes, the football team was playing on the field and people were receiving the ball.
"Lincoln, you were supposed to reserve the land. "
"I thought you did it?"
Ricky's funeral home was really ruined. This makes Lucy sad and her negative emotions are felt by Hawk Moth.
The black butterfly fits into Lucy's shovel.
{Undead Princess. I offer you the power of the hereafter. You will have all the power of a spectral being. In return, you have to bring me the superhero jewelry.}
"I accept. "
Black smoke covers all of Lucy, transforming the gothic girl into a ghostly version of Eight of Spades. The version has a slightly torn purple hooded cape armed with a shovel.
Undead Princess arrives on the football field.
"Death, come back to life and obey me! Queen of the Undead! "She plants her shovel on the ground which releases purple energy into the ground.
All animals that died in the previous school years have come back to life.
Hamster, fish, guinea pig that was buried under the school have come back to life thanks to the power of Princess Undead.
"I really should have buried them somewhere else. "The director said.
"Zombie army, attack! "
Dead animals attack everyone and bite them.
Those who have been bitten are also transformed into zombies.
Lincoln hurries to find a place to transform.
"As, Let's Play!" The boy with the brown hair turns into a superhero alter-ego.
Ace of King throws his cards at the zombies to stop them. He uses the billiard balls to knock them down.
"They're too many. Ladybug and Cat Noir where are you? "
Lee observes the entire scene hidden in the school mascot costume.
"Lee, this villain might be a real problem for them. If the zombies bite them, Hawk Moth will be able to easily grab their Miraculous. "Sass said.
"You're right. Sass, scale Slither! " Lee speaks the words to transform.
The snake Kwami is sucked into the green bracelet. Lee wears a green suit with a mask and his weapon is a harp.
"Second Chance!" He pulls the serpent's head back from the bracelet to activate his power.
During this time. The three superheroes fight against Princess Undead and her army of zombies.
The three are surrounded by the zombie horde
"They're too many. Do you have any idea of my lady? "Cat asks.
"Yes, Lucky Charme!" Her power spawns a coffin flower ring. "How can I use this?"
"While you are thinking, I will - ?!" He gets bitten by the zombie hamster.
"King's Ace!" Cat is also bitten by a zombie hamster.
"Ace! Cat!" The ladybug girl tries to help her two friends but the zombies stop her and end up getting bitten too.
{Excellent, now bring me their Miraculous.}
By the time the Undead Princess was going to do it. Viperion unleashes his power.
They go back in time before they get bitten. That is, when Ladybug uses her Lucky Charm.
"I have an idea. Ace of Kings, I will need help. "She whispers her plan.
"Including. Full Deck! " Eight of Spades appeared.
Eight of Spades uses his shovel to trace the ground.
"It's time to bury yourself! Cataclysm! The cat superhero uses his destructive power to bring down the ground where Eight has drawn.
The zombies all fall into the hole. The villain is alone.
Ladybug rushes to Princess Undead, she puts on the flower ring.
"What!?" She cannot move and Ladybug takes the opportunity to destroy the shovel.
The black butterfly came out and was purified. With her Miraculous Ladybug, all the victims are back to being as they were before.
The dead animals are in the underground again, and Lucy goes back to her normal life.
After this event. Lucy asks Haiku to help her.
The two Gothic girls make this funeral memorial. Everyone remembers Ricky the Rooster.
