Prompt: Izuku found an app where he can shove that his squad members faces onto elves and make them dance! After gathering everyone together, he shows them the results!
Okay, this is an actual app. There is a link for each one because I actually did it.
You're welcome.
I also did this in interview style to make this easier to read.
This will be deleted on the first of January because the links won't work anymore by then.
I also didn't do reactions to all the videos because they either didn't work or they were boring. I'll still have the links at the bottom.

Nemuri, Hizashi, Izuku, and Shouta sit on the couch in that order looking at a large TV. Beside them, Tensei sits in a wheelchair.

Tensei: It's not my fault the hospital asks for me every single day!

Izuku: You could have visited us once! We rarely have the whole squad together because of you!

Tensei with a sad puppy face: I'm sorry.

Izuku: If you think I feel guilty with that face, I don't.

Shouta: Just get on why we are here so I can get out.

Izuku: Rude. Anyway, y'all ever heard of the old app Elf Yourself?

Hizashi: I have!

The rest of them have not.

Izuku: See, this is why I get along with Zashi best. He gets these old cringy things like I do.

Hizashi: YEAH! Wait, did you- PLEASE TELL ME YOU DID WHAT I THINK YOU DID!

Izuku: Of course I did. I can't really make Tensei dance anymore, and Shouta just constantly breaks my heart over it.

Shouta: I said I'll dance at your wedding.

Izuku: YOU SPECIFICALLY SAID THAT BECAUSE YOU KNOW I WON'T HAVE ONE!

Shouta: Exactly.

Izuku: The levels of depression are rising by the millisecond.

Nemuri: Oof. So we are watching something?

Izuku: Yes. I shoved our heads on elves that dance. I haven't watched these videos yet, so this is a first reaction for all of us.

Nemuri: I'm not surprised you found this.

Izuku: Let's get started!

First Video: Beach Party

https://elfyourself.com?mId=41953

The video starts.

Tensei: OH MY GOSH, I'M STANDING!

Hizashi: OH MY GOSH, IZUKU IS NOT SHORT!

Izuku: YOU FUCKING BITCH!

The recording has been paused due to Izuku attempting to beat the shit out of Hizashi. They had to be rearranged so that they are on opposite sides of the couch and Nemuri and Shouta are in the middle to separate them. Hizashi requires an icepack now.

Hizashi: You can't blame me for making that joke!

Shouta: You said it right next to the kid who does not hesitate to attack.

Tensei: Hizashi's dumbest move this year.

Izuku: NO FUCKNIG SHIT, SHERLOCK!

Shouta: I'm not saving you next time, Zashi.

Hizashi looks sad. Nemuri pats him.

Nemuri: Don't worry: I will.

Hizashi is now happy.

Shouta: Can we get on with the video? I still want to take a nap.

Izuku: Your fault your sleep schedule is shit.

Izuku starts the video.

Tensei with tears in his eyes: I'm moving!

Nemuri: Izuku be dropping it like his momma!

Izuku: I been dropping it way before you, ma'am.

Hizashi: Are we just ignoring the fact that Izu is just holding a guitar? Like, they could at least pretend to play it.

Izuku: You're character did the same thing for a moment, so shut it.

Nemuri: Guys, we should appreciate that this is the closest we will ever see Shouta to dancing.

Hizashi: Amen.

Izuku: Amen.

Tensei: Amen.

Shouta already looks done.

Hizashi: This is squad energy to the max.

Tensei: I'M RIDING A DOLPHIN! FUCK EVERYONE ELSE! I GOT A GODDAMN DOLPHIN!

Izuku: Probably because your legs collapsed on your while dancing, so they made you take a break by riding a dolphin.

Tensei: I don't care for the reason! I'm riding a dolphin!

Nemuri: Those hip swings, though. I don't think Hizashi or Shouta can do that.

Hizashi: I can if I try!

Shouta: I won't.

Hizashi: I'm still concerned that Izuku is not playing it.

Izuku: Tell that to the actor, not me.

The video ends.

Izuku: What do y'all think?

Tensei: I got to ride a dolphin and move, so I love it!

Nemuri: It's weird, but also cute.

Hizashi: I'm so happy you found this!

Shouta: Hate it.

Izuku: Don't worry: here are plenty more to look at!

Second Video: Feliz Navidad

https://elfyourself.com?mId=41988

The video starts.

Izuku: You can't say shit when we are all holding instruments and not playing them now.

Hizashi: Yeah. When I heard Feliz Navidad, I thought it was going to be the hyper one that goes 'FELIZ NAVIDAD! I WANNA WISH YOU A MERRY CHRISTMAS!'

Izuku: I know right?!

Tensei: What does Feliz Navidad mean?

Izuku: Merry Christmas in Spanish.

Tensei: That makes sense.

Nemuri: Honestly, I'm not feeling much from this video- OH, LOOK AT SHO, TEN, AND ME DROPPING IT!

Tensei: I remember when I could do that to get the ladies.

Izuku: Oof.

The video ends.

Hizashi: I think we were all disappointed besides for the drop, and that didn't make sense.

Izuku: I agree. I think they meant to get the other version, but realized it was copyrighted so they replaced it with this.

Hizashi: That's sad.

Izuku: Yeah.

Tensei: Oof.

Nemuri: It's still a nice idea.

Shouta: I still hate it.

Video Three: Classic (Warning: This is cursed)

https://elfyourself.com?mId=42032

The third video starts. As soon as they appear, everyone is screaming.

Nemuri: DELETE THIS CURSED SHIT! THIS IS HORRIBLE! I RATHER DIE THEN WATCH THIS!

Tensei: YES, THIS IS DISTURBING!

Shouta doesn't bother watching. Meanwhile, Hizashi and Izuku are laughing their asses off over it. Nemuri goes over and immediately turns off the video.

Izuku: Hey, what gives?!

Hizashi: Yeah, that was the good cush!

Nemuri: I ain't watching anymore if there is more of that!

Izuku: Fine! I'll find something without it!

Nemuri: Thank you. Love you, dear.

Izuku grumbles.

Video Four: Cats!

https://elfyourself.com?mId=42043

The video starts, and Izuku is already disturbed. For once, Shouta is paying attention.

Izuku: I hate this.

Shouta: I like this one. Keep it on.

Hizashi: You just don't like it because there is cats in it.

Izuku: Am I not allowed my opinions?

Tensei: In this squad, you fight for you opinion.

Nemuri: You have to be honest: for how much Shouta and Izuku are put together in this one, it's adorable.

Izuku: Shut up.

Tensei: The kitties are adorable!

Izuku faces away from the TV for the rest of the time. The video eventually ends.

Shouta: I know what to torture you with now.

Izuku: Rude.

Shouta: This is my favorite. Everything else is bad.

Hizashi: Aww, babe! I agree with him!

Nemuri: Me too!

Tensei: Uh-huh!

Izuku: My life is flashing before my eyes.

Video Five: Elfspanol

https://elfyourself.com?mId=42075

The video starts.

Nemuri: Oh, this is romantic! I hope that's for Sho and Zashi!

Izuku: Yeah, no. I don't think that's Sho.

Hizashi: I don't think half of this is possible with Izu because he's so short!

Izuku glares at him.

Tensei: I have a dancing partner! You would dance with me, right, Sho?

Shouta: No.

Tensei: HE'S EVEN DOING THE LEG THING!

Shouta: In your dreams. I'm glad Nemuri is by herself.

Nemuri, who has the been sad for the whole video: Go fuck yourself, Shouta.

Shouta: That's what I have Hizashi for.

Hizashi is blushing.

Tensei: Holy shit!

Izuku: I didn't think a joke like that from him is possible. Am I rubbing off on you?!

Shouta: No.

Izuku: Damn.

The video ends.

Nemuri: That's my least favorite.

Izuku: Expected.

Nemuri: I will knock you out.

Shouta: Don't. Also, hate it.

Tensei: I loved it!

Hizashi: Me too! But I deny I will ever get Shouta to dance with me like that.

Izuku: Maybe at your wedding.

Hizashi: Shit, you right. Shouta, let's get married!

Shouta, blushing: Not now, idiot.

Hizashi: Awww.

Video Six: Hip Hop Shop

https://elfyourself.com?mId=42102

The video starts.

Tensei: Can I just say that it's not surprising that Nemuri is leading the group inside a store?

Hizashi: For how much she shops, yeah!

Shouta: You go just as much as her.

Hizashi: No need to call me out like that!

Nemuri: I'm just happy to finally be the leader!

Izuku: Honestly, this is the squad vibe in a nutshell.

Nemuri: True.

Hizashi: True.

Tensei: True.

Shouta, sighing: Sadly true.

Nemuri: HOLY SHIT, THE BOYS ON THE FLOOR!

Hizashi, AND SHO IS IN THE MIDDLE!

Izuku: That's like the one find I wouldn't do. You have any idea how disgusting those floors are?

Hizashi: It's for the moves, Izu!

Tensei: I FINALLY HAVE A SINGULAR SCENE WITH IZU!

Izuku, laughing: Want to be around me that much? Am I cooler than your brother?!

Tensei: No. Tenya will always be coolerthan you.

Izuku: Oof.

Nemuri: The hats are so cute!

Izuku: They are supposed to make us gangster.

Nemuri: I don't care!

The video would end.

Izuku: I think that one is my favorite only because it's the most accurate representation of us.

Hizashi: It's just overall better.

Nemuri: I like it because I was the leader!

Tensei: It's my favorite too!

Shouta: The cat one is still mine.

Izuku: Since that was the last video, any final thoughts?

Tensei: There was too much of Izu and Zashi put together and not enough of me.

Hizashi: Not our fault we get along so well in this!

Izuku: Yeah!

Nemuri: I think it's a cute idea. I would definitely watch it again!

Shouta: Cat one is good. Everything else is cringy.

Izuku: Only because it had cats.

Shouta: Exactly.

Izuku, sighing: Fine. Welp, you're free now!

Shouta immediately gets up, goes to another couch in the room, and passes out.

Tensei: I'm going to bother Tenya. Later!

Tensei rolls out.

Nemuri: I have papers to grade. See you, dearies!

Nemuri struts out. Izuku and Hizashi look at each other.

Izuku: Wanna prank the school?

Hizashi: Sure!

The two head out.
