Lincoln marked April 1st on his calendar with a red marker as he spoke to the audience. "Tomorrow is April Fools' Day. Every year, my sister Luan creates a prank apocalypse and no one is spared! I present to you Luan Loud's April Fools' highlight reel.

He begins showing a montage of Luan's April Fools' Day. Pranks on the Loud Family.

First, the loud siblings are looking at their furniture, which is tacked upside down to the ceiling.

Luan: I'd say this prank's a little over your head!

She laughs.

Second, the siblings open the door to find a room full of chickens.

Luan: Seems to be your 'clucky' day

She laughs

Third, loud siblings are looking at their house all wrapped up in wrapping paper.

Luan: (tips through a window) I guess that's a 'wrap!'

She laughs

Fourth, the loud siblings are trapped in humongous gelatin.

Luan: Aww, look at the loud family gettin 'jiggly' with it!

She laughs.

The pets' fur and Walt's feathers got shaved off and are scared.

Luan: (holding a buzz shaver) I shaved the best for last!

She laughs before the video ends.

Lincoln: see what I mean? Nobody's safe from that evil pranking genius. But 'this' year's gonna be different. Luan is 'not' gonna prank me! Because I got an April 'Fool' Proof plan. (Towards his door) you're not the only one who can make a pun, Luan!

Lincoln opens his door to reveal Lily wearing a watermelon helmet and diaper, Lynn Jr putting on padding, and Lola coating herself and Lana in bubble-wrap.

Lana: bubble-wrap me next

Lucy: (enters with her head inside a gargoyle head) I need more armor."

Bloody Bunny: (talking to herself) alright I need a plan to hide from Luan's prank rampaging. Should I hide inside the ventilation tomorrow? No. Last time I hid there I nearly got my fur covered in red paint. Should I go hide underneath the bed? No bad idea. She'll probably set up a cream pie booby trap here or worse. What to do, what to do.

Lynn Jr: (as Lisa enters in army gear) where's my helmet?!

Lori: (talking on her smartphone) Bobby, we have to cancel all our plans in April.

Bobby: (on the phone) why babe?

"Because Luan might shave my eyebrows off again! and it takes a month for them to grow back."

Luna: (following Lisa) C'mon Lisa! Let me hunker in your bunker!

Lisa: you should've been more prepared. We'd known this storm was coming for 364 days.

She walked away.

Luna: (dropping to her knees) please! give me! shelter!

Lincoln walks by whistling when Lola dashes out in front of him mm

Lola: Arms up, Lincoln! You turn for bubble-wrap.

Lincoln: (puts a hand in front of Lola.) Not this year, Lola. I am not getting pranked.

The loud siblings were surprised by this and started to chatter.

Lola: it's never been done!

Lynn Jr: Are you crazy?

Bloody Bunny: Lincoln! You have lost your mind. No one cannot escape nor hide from that evil prank master joker!

Lincoln: Ladies! Ladies! I got a plan! I'm simply gonna lock myself into my room till the day's over. I've got snacks, video games, and those to pee in, which I call the 'twinkle tube'. Patent pending.

Lori, Leni, Luna, Lynn Jr, Lucy, Lola, Bloody Bunny, and Lily: Ew!

Lara: Cool

Lincoln: (points to his window) it goes out the window! The point is, I'll never have to leave my room so Luan will never get me.

Bloody Bunny: Disgusting idea, but I like it. However, if you're going to lock yourself in that room then I'm coming in. But how could we stop her if she pranks us inside our room?

Lincoln: way ahead of you, I also got a plan to board up the door, window, and the vent.

Bloody Bunny: smart.

The loud siblings started to get frightened by the sound of sausage hitting on the stair rails as Luan slowly came upstairs while holding a sausage.

Bloody Bunny: oh no,

Luan: Ohh! It's Pranksmas Eve... and I'm just bubbling with excitement.

She pops a piece of Lola's bubble wrap and walks away.

Lola: I'm going to need more bubble wrap! And a fresh pair of undies

Lincoln comes out of Lola and Lana's room. "Thanks for the lumber, Lara! I'll return it on April 2nd."

He walks away with the lumber.

Lana: mahogany was a good choice. That'll hold nicely.

Lincoln closes his door, uses the drill to seal the nails and mahogany on it, then puts a chair by the doorknob.

???: (offscreen) way to go, Lincoln.

Lincoln: Thanks, wait what?

He turned in the direction up the voice and he was surprised to see Bloody Bunny.

Lincoln: (confused) how did you-

Bloody Bunny: secret passage, I built them everywhere around the house ever since I first stepped in here. I could tell you more of the details but it will be boring to you.

Lincoln: oh! So that's how but does-

Bloody Bunny: none of our sisters including Luan knows, except for Lisa. I asked her to make them for me but some I made for myself.

Lincoln: smart thinking. Don't worry I'm going to tell none of them about it.

He takes out his walkie-talkie. "Clyde, wanna hang out tomorrow? I built us a fortress with snacks, games, and a 'tinkle tube' patent pending.

Clyde: On Pranksgiving? No way! Not after what happened last year.

(Flashback!)

Last year on April Fool's Day where Clyde steps on a rope as one of Luan's prank traps. Water spray on his face and he is covered in hay. Luan's laughing can be heard. Then, a flock of crows comes to attack him as he screams.

(Flashback ended!)

Clyde looks a little scared.

Lincoln: but nothing's gonna happen this year. I've got an April Fool proof plan. (ringtone sounds) hang Clyde, Ronnie Anne just texted me.

He checks his phone. "She said she's coming over tomorrow with a present for me." Lincoln gasps "She can't come over tomorrow! She'll get nailed by Luan's pranks and then pulverize me!"

Lincoln: I can't do that! That will definitely get me pulverized!

Clyde: you gotta get Luan to call off Prankapalooza. Appeal to her humanity. Beg if you have to!

Lincoln: good idea just as soon as I get the mahogany off my door!

He hangs up his walkie-talkie

Bloody Bunny: Hey, Lincoln?

Lincoln: (turns to face her) yeah?

Bloody Bunny: before you may go out there and beg the joker prank queen of mayhem I must warn you...

Bloody Bunny goes in front of him. "Luan won't call off her prank apocalypse that easily the moment you'll beg her to, she'll just refuse your proposal and continue her work for tomorrow of her prank rampage. Don't you get it, she can't be reasoned with. She can't be bargained with. She doesn't feel pity, or remorse, or fear. And she absolutely will not stop, ever, until she'll prank us all."

Lincoln: I know, but I have to try.

Bloody Bunny: then I wish you luck.

Lincoln: thanks

He begins to remove the nailed wood off his door.

(Luna and Luan's room)

When Lincoln arrives into the room, Luan turns around in a jester chair to face Lincoln while she has Cliff on her lap.

Lincoln: Luan! You gotta call off Prankageddon! Ronnie Anne, it's coming over tomorrow and I can't let her get pranked!

Luan: okay.

Lincoln: (surprised) really? Wow, that was easier than I-

Luan: April Fool's practice! Lincoln, you know the April Fool's rules. Anyone who sets foot in our property is fair game. Speaking of which, is Clyde coming? 'Cause I'd love to say 'hay!'

She chuckles insanely.

Lincoln storms back to his room, puts the mahogany back on his door.

Bloody Bunny: let me guess the begging didn't work

Lincoln: no, it did not

He then took out his walkie-talkie and called Clyde.

Lincoln: Clyde! Pleading with Luan didn't work! she's an animal!

He hears a cat noise. "What was that?"

Clyde: Oh, that's Cleopawtra. She's been feisty lately so we put her in a timeout crate.

Lincoln: timeout crate

The white hair boy gets an idea. "That's it!"

Lincoln runs to brainstorm his idea and tries to pull the mahogany off the door.

Lincoln: Why did I choose mahogany? Bloody Bunny, can you please help me with this

Bloody Bunny: I'll help, but what's in it for me?

Lincoln: I'll give you carrots and carrot cake first thing tomorrow.

Bloody Bunny: deal.


In the basement, Lincoln flicks the lamp on.

Lincoln: (to his siblings who were not Luan) we're all here? good! So about Laun…

Lola: shh! She has ears everywhere!

The pink princess turns on the washing machine. "I saw this in a mob movie once. She won't hear us over the noise."

Bloody Bunny: smart

Lincoln: we all know tomorrow is going to be awful. But it doesn't have to be. If we combine forces, we can prevent Luan from setting up any pranks in the first place.

Lynn Jr: uhhh, how exactly are we going to do that?

Lincoln: let me tell you my plan.

Lisa: better make it snappy. We're almost done with the spin cycle.

Xx

Later that night in Luna and Luan's room, Luan was in the bed snoring. Luna gets up and gives a bird-like call to signal that Luan is asleep. Everyone then enters the room. Luan then opiates her eyes as her siblings tie her down, trap her in a cage, and keep her fingers together with Chinese finger traps.

Luan: (enraged) let me... out of here!

Lincoln: okay

Luan: (surprised) really? Wow! That was easier than I-

Lincoln April fools! were not letting you out until April 2nd!

The other siblings begin to cheer.

Lynn Jr: that was a 'crate' plan, Lincoln!

The siblings laugh during a rimshot. Except for Bloody Bunny who let out a chuckle.

Lori: I've been 'creating' for this moment all my life!

The siblings laugh again.

Lana: Well, better 'crate' than never!

The siblings laugh again.

Leni: you're in a crate!

The other siblings don't seem to get it. "Get it?"

Bloody Bunny: (to Leni) I don't get it

Lincoln: maybe we should just go to bed.


The next day, Luna is heard screaming. The cage is now broken, meaning that Luan just escaped, somehow.

Lola: (panicked) we're doomed! Luan escaped, and now she's gonna to be mad

Bloody Bunny and Lincoln: how could this have happened?!

Luna: she's a black magic woman, dude!

Lincoln holds up a loose chain. "I gotta get my money back for these."

As Lincoln pulls the chain, it sets up a bucket full of honey that spills on him, followed by a blast of feathers while the siblings gasp in surprise.

Lisa: peace out. I'll be in my bunker.

She dashed off.

Bloody Bunny: (murmured) cowardly, Egghead.

Lincoln: everyone else to my room! We'll be safe there.

As the siblings run towards Lincoln and Bloody Bunny's room, their parents show up by the stairs. Rita is wearing a padded gear while Lynn Sr is wearing bubble wrap.

Lynn Sr: what's all this ruckus about?

Lori: Luan's on the loose! Take cover!

Rita: but we thought you locked her up

Lynn Sr: Plan B! Retreat! Retreat!

He and his wife once back downstairs.

Lincoln heard his ringtone sounds as she checked on his phone. "Oh no! Ronnie Anne's on her way? Could this day get any worse?

He bangs his head on the wall. A rope on the wall is attached to the vacuum cleaner that's on the ceiling and it's bag opens up to dust on Lincoln.

Lincoln: well, that's my answer. But on the plus side, that's one less prank Ronnie could suffer.

He gets an idea. "That's it! If I set off all the pranks in the house, there won't be any for her."

Lynn Jr: Lincoln! it's not safe out there!

Lincoln: save yourselves! I got a job to do.

Lucy: Don't worry Lincoln, I'll plan your funeral.

Bloody Bunny: hold it!

The white bunny doll comes out of the room. "I'm coming with you. We still made a deal yesterday."

The loud sisters gasped in shock. "What?!"

Lori: Bloody Bunny! Have you lost your mind?! Don't be a fool! Luan put every prank all over the house you won't stand a chance!

Bloody Bunny: I know, bossy lady. But I don't care. Even if I can survive this prank apocalypse without getting pranked then I'm lucky if not well I try my best.

Lola: Bloody Bunny, you have a brave soul.

Bloody Bunny: Lola, I'm not even sure if my soul has bravery inside this object body of mine and if I don't survive, invite me over to your tea party.

Lola: (surprised) really?

Bloody Bunny: (head shook) no, not really.

Lucy: I'll plan both your funerals.

The sisters close Lincoln and Bloody Bunny's bedroom door and places the mahogany on it. Lincoln puts on a helmet and takes out the map of a house and circles the kitchen.

Lincoln: We'll start by de-pranking the kitchen.

Bloody Bunny: then let's get it done.

They go downstairs and look at a sign that says 'kitchen this way' while it points to the open front door.

Lincoln: Kitchen this way? Ha! Does she think I'm done enough to fall for that?

Bloody Bunny: Nope, but she does know someone who is dumb.

Lincoln takes the original route and goes into the kitchen and goes into the kitchen and finds grease on the floor.

Lincoln: well, here goes nothing.

Lincoln cautiously walks on the grease trap causing a boot contraption to kick him into the fridge while a box falls on his head. As he gets up, he slips on the grease, opens the fridge door, and is socked right on the face by a boxing glove on a spring. The force of impact propels him into the stove.

Lincoln: ow!

His helmet breaks apart, and a bunch of vicious raccoons pop out of the stove and attacks Lincoln as he screams in pain.

Luan popped in from the other room. "I made that dish from 'scratch'!" She laughs.

Bloody Bunny whistles getting the attention of the raccoons. "Step away from my foster brother, you animals!" She drew out her sword. "I'm going to give you two options: leave this house or stay and you will die."

The raccoon growls at her (translation: no! We refuse not to listen to you.)

They begin to go towards her and attack her.

Bloody Bunny: (sighs) I was hoping it was going to come to this.

Bloody Bunny launches herself, tossing her sword before releasing, at the first raccoon in its heart and sending its flying into the wall.

She then tossed three throwing stars to kill all three raccoons at once. Bloody Bunny then turns to see the last remaining raccoon who seems to be afraid of her.

It decided to run away.

Bloody Bunny: I do not appreciate you becoming a coward!

The former human girl drew out a throwing knife and launched it killing the raccoon behind its back.

Bloody Bunny: I hate it when raccoons become cowards instead of warriors, animals these days never learn.

Lincoln: Thanks, Bloody Bunny.

Bloody Bunny: Don't mention it.

Lincoln: By the way can you train me like you?

Bloody Bunny: (sarcastically) sure, why not. I'll train you

Lincoln: Really?

Bloody Bunny: No.


Meanwhile, in the backyard, the loud parents are at Lisa's shelter.

"Lisa Marie Loud! Let us in!" Rita demanded as Lynn Sr knocked on the shelter.

Lisa from inside the bunker. "I'll need some of your assurances in return! One, I will never again be punished for the explosions in or around the house!"

Just then, Luan appears from out of a window with a pile of Lily's stinky diapers. "Happy April 'stool'!" She prepares to aim one with a slingshot towards her parents.

Rita: aren't those diapers? She wouldn't!

Lynn Sr: (frantically pounds the shelter) whatever you want! Just let us in!

Lisa opens the shelter while holding a contract. "Sign here, here, and initials here."

After the parents sign their names, they hide while Luan shoots diapers at them.


Back with Lincoln and Bloody Bunny…

Lincoln looks at the map and finds a flying flower bag in the bathroom and screams. He catches it but the flower has a timer to explode.

Lincoln: uh oh!

The flower bag explodes and Lincoln starts coughing as he finds the sink to turn it on but the water splashes him.

Lincoln: Towel! Towel! Towel! Where's the Towel?

As he blindly searches for a towel, he finds a raccoon and uses it to wipe himself but after he opens his eye, he finds out he has one and screams as he runs away from it.

Luan pops up from her room. "Don't give up. no one likes a 'critter' she laughs.

Bloody Bunny jumped into the air and swung her sword cutting across the raccoon's body as blood sprayed all over her fur white turning it to red, Bloody Bunny landed on the floor.

Bloody Bunny: I love killing wild animals these days.

She wipes the red blood off her blade before returning it to it's sheath.

Lincoln: Thanks

Bloody Bunny: Like I said don't mention.


(In Lincoln and Bloody Bunny's room)

Lori: I think if we ration the food, we should be okay

Lana: what does "ration" mean?

She eats a bag of chips and drinks some apple juice. The others glared at her

Lola: (scoffs) Typical. now someone has to go into the kitchen for more supplies.

Lori, Leni, Luna, Lynn, and Lucy all talk at once.

Lana: (gasps) let's draw straws!

Leni: (sighs) I'll just go. I know I'm going to lose. I'm a terrible artist.

Lucy; actually, that's not what-

Lola covers Lucy's mouth, "Good luck Leni!" She and her other sisters shove Leni out of Lincoln and Bloody Bunny's room and put the mahogany back on the door.

Leni makes it downstairs and finds the sign that says 'kitchen this way' and reads it.

Leni: 'Kitchen this way?' Oh. Thank you, sign.

She finds another one that says the same thing. "Thank you, sign!" She found another sign. "Thank you, sign! Thank you, sign!" She keeps following them into the town.

In the living room…

Back with Lincoln and Bloody Bunny…

Lincoln: (looks at map) okay. Living room. So far, so good.

Then a red line comes when Lincoln crosses it and a projector is switched on, showing in an embarrassing video of Lincoln kissing a balloon with a girl's face on it while Clyde is beside him.

Lincoln: I think this is how you kiss a girl.

He kisses Edwin balloon.

Clyde: Don't hold back, Lincoln. Girls like a guy with passion!

Lincoln was still kissing the balloon until it popped.

Bloody Bunny: (smirkes) Wow! That's the funniest and embarrassing video I have ever seen in my life.

Lincoln: I can't let Ronnie Anne see this.

He goes on the couch. "Stop! Stop!"

He tries to stop the film, but the count has a spring and Lincoln goes up to the ceiling and gets stuck by sticky fly papers.

Bloody Bunny: (sighs) unbelievable, Lincoln.

Bloody Bunny took out a throwing knife and tossed it at the projector, destroying it.

Then Lincoln falls down on the couch and gets back up.

Luan appears. "Looks like 'spring' is in the air." She chuckles.

Bloody Bunny: (angry) get out of here! Before I come over there and knock some of your teeth out!

Lincoln: (looks at the map) Just got to finish the bedroom!

Bloody Bunny: Alright.

The house's exterior is shown as Lincoln and Bloody Bunny get by Luan's pranks traps. Afterwards, the two were tired, beat up and dirtied as Lincoln got a call from Clyde.

Clyde: Lincoln! What's happening? Lucy just invited me to you and your foster sister's funeral.

Lincoln takes a mousetrap out of his eye and screams. "Ow! Bloody Bunny and I've been setting off all the pranks in the house so Ronnie Anne doesn't get hit." He lifts hit his shoe as sand pours out. "We've gone through every room except Leni and Lori's.

Clyde hangs up.

"Clyde? Hello!?"

"Looks like your friend has abandoned you." Bloody Bunny is completely covered in red, orange and blue paint everywhere all over her fur with cuts and bruises. "Or hasn't he?"

The doorbell rings as Lincoln and Bloody Bunny go downstairs to open the door, showing it was Clyde.

Clyde: I volunteer to clear Lori

He goes to Lori and Leni's room offscreen as he gets attacked by Luan's prank traps. He comes back downstairs in the same condition as Lincoln and Bloody Bunny.

Clyde: it was worth it. Lori's room smells like apple cinnamon.

"That might be this pie." Lincoln puts the pie on his head and sighs. "Well, that's it. The loud house is prank free."

Bloody Bunny: for now, Lincoln.

"Right, for now." Lincoln high fives Clyde as the latter walks away and faints. Ronnie Anne arrives and is surprised when Clyde faints, before looking annoyed.

Luan chuckles as Ronnie Anne arrives in. "I won! You thought you'd outsmart me, but that you two got the worst pranking ever!

Bloody Bunny: I hate to break it to you prank master joker buffoon, you didn't win.

Lincoln: Yeah! We only set off those pranks because Ronnie Anne was coming over.

Ronnie Anne looks rather touched at hearing this.

Luan: Yeah! well who do you think invited her over, genius?

Ronnie Anne's expression turns to a confused look.

Bloody Bunny: What?

"I knew I had to lure you out of your room, so I called Ronnie Anne, and told her how you loved April Fools Day. And here she is, to deliver the final blow."

Lincoln turns to Ronnie Anne, who pulls a pie, with a villainous looking smile on her face.

Lincoln closed his eyes and braced for impact.

"Oh no, you don't." Bloody Bunny reaches out for her sword. At first she thought Ronnie Anne was going to throw the pie at Lincoln's face. But instead she threw the pie in Luan's face.

Bloody Bunny: Wow for a minute you almost had me there.

"Huh?" Lincoln opens his eyes and finds what happened. "But why'd you do that?"

Ronnie Anne: you guys took all those pranks for me. It's the least I can do. Come on, let's draw some eyebrows on you and go get a milkshake. Bloody Bunny, you wanna come?

Bloody Bunny: sure, why not Lincoln still owns me some carrots and carrot cake.

The three leave the house to hang out.

Luan: that girl's keeper

Soon afterwards, the family came out of their hiding and relieved the prank fest is over

Lynn Sr: Is it really over?

The sisters agreed.

Rita: Wait! Where's Leni?

Lisa looks at the 'kitchen this way' sign. "I have my suspicions."

Lynn Sr: Okay, everybody in the van. Let's find Leni, and then afterwards, frozen yogurt to celebrate! Ha! Ha!

Everyone cheers and hurries to the van. But just as the fan is about to start, the airbag explodes, splattering blue paint everywhere in the van.

Loud Family: (furious) Luan!

Luan: (to the audience) aw, the end of April Fools Day always make me feel a little 'blue.' (Laughs) get it?
