It is a tense showdown between the greaser John and the emo Lars. As they prepare to tackle each other in the middle of the dance floor, Lincoln and Clyde abruptly distract them by oddly dressing themselves in oversized winter coats and fedora hats and performing this number, at the start from Luke's synthesizer rift. Lincoln starts it off.

I got this feeling inside my bones
It goes electric, wavey when I turn it on
All through my city, all through my home
We're flying up, no ceiling, when we're in our zone

"Wait…Is your brother singing a song I love?" John furiously asks. Just as he is distracted, Lars punches John by the elbow. "Hey! You cretin!" John attempts to charge Lars, but he surprisingly finds himself digging into Lincoln's voice singing his favorite song.

I got that sunshine in my pocket
Got that good soul in my feet
I feel that hot blood in my body when it drops, ooh
I can't take my eyes up off it, moving so phenomenally
Room on lock the way we rock it, so don't stop

Everybody else joins in the jam as Lincoln and Clyde cooperatively perform "Can't Stop the Feeling" by Justin Timberlake. The whole auditorium is filled once again with vibrancy after two slow dances and a jazz overture.

And under the lights when everything goes
Nowhere to hide when I'm getting you close
When we move, well, you already know
So just imagine, just imagine, just imagine

In any way possible, every student in the hall dances along with the number. John finds this so infectious that he cannot help but go along with the flow and participate in dancing. "Oh this is so precious! I must!"

Lars, meanwhile, is stunned at John's sudden shift in tone. He can accept that his enemy could be a fan of pop songs but he never would expect for him to dance along to them uncontrollably. It is truly out of his element that just triggers curiosity to such a one-sided bully. Nevertheless, Lars finds this as advantageous.

Before Lincoln and Clyde go to the chorus, a horde of students, including John, huddle by the middle of the dance floor and follow the duo's jiving moves. This really apes the cliché of kids' movies needing a dance number near to the end of a movie.

Nothing I can see but you when you dance, dance, dance
Feeling good, good, creeping up on you
So just dance, dance, dance, come on
All those things I shouldn't do
But you dance, dance, dance
And ain't nobody leaving soon, so keep dancing

In the heat of such a sporadic moment, Lincoln and Clyde unexpectedly get lifted up by the Winter Dance guests and cheered by them. They still continue to sing.

I can't stop the feeling
So just dance, dance, dance
I can't stop the feeling
So just dance, dance, dance, come on

Meanwhile, Danny bursts from the door, having taken an upper hand to Lynn, and gets stunned to see his brother mindlessly dancing to a dance-and-song number, performed by people he despises. "Hey John, would you cut the nonsense on dancing to this song?!" he loudly warns him, but he ignores his pleas. "Oh that's it! I shall show those boys who they should dance to!"

Suddenly, Boy Lynn catches up to Danny and kicks him by the face. "Oh no you don't!" He then overpowers him by stomping on his head and burying his face to the floor. "If you dare mess with my brothers, you mess with me!" After that, noticing the performance has shifted to the fast songs, Lynn goes through the crowd and joins his brothers onstage to the drum set. Danny tries to catch up with him but he is subsequently surrounded by guests who converge at Lincoln.

Ooh, it's something magical
It's in the air, it's in my blood, it's rushing on
Don't need no reason, don't need control
I fly so high, no ceiling, when I'm in my zone

Meanwhile, the six other goons who earlier were tied up together enter the dance floor to finish the job. But still, while all being tied to a rope nonetheless, they end up dancing mindlessly. Simon and Nick, who showed with bruises on their faces after Lexx and Leif beat them up harshly, arrives on time to see their fellow cronies asininely dancing.

"Hey, you fools! What are you doing?!" Simon shouts at them.

"They can't hear you, mate. The song's too loud," Nick utters.

"Oh quit your observations and help me cut them loose," Simon persuades.

However, one of the guys takes them by the hand and drags them to the posse, ending them being tied up alongside with them. Now, the two are stuck with the six.

"This is such rubbish, mate!" Simon reacts while feeling choked from how tight the rope is.

"You tell me. I can almost question how we end up in a gang of monkeys," Nick responds while being pressed to Simon's chest. With no other way out, the two just go along with the six's mindless jiving.

Lexx and Leif stumble upon them as they enter back at the auditorium.

"Look at how they go, Lexx," Leif utters. "But they're still a threat."

"I just got the solution for that one, Leif," Lexx replies with a grin.

With that, Lexx and Leif retrieve one ball carrier that is filled with Mikasa basketballs and open it to release the balls for the goons to trip over. Sure enough, thanks to being distracted on the song, they do trip over and land on the carrier altogether. Lexx has them caged there, and the two push the cart away to the hallway. The eight goons end up being slid on the cart, having to come across or hit several students who are passing by and knocking out their other three men. They all end up crashing to the janitor's mound, where he places and rinses his mop. And in that note, the eleven give up for assisting John and Danny.

'Cause I got that sunshine in my pocket
Got that good soul in my feet
I feel that hot blood in my body when it drops, ooh
I can't take my eyes up off it, moving so phenomenally
Room on lock the way we rock it, so don't stop

On the other hand, Bebe and Ronnie Anne carry Loki to the backstage, where they see Loni and Leon dancing to the song number.

"Loni! Come here quick!" Bebe calls him out, to which he responds instantly by approaching them

"Loki, what happened to him?" Loni asks as he carries Loki for them and brings him to a nearby chair.

"Those goons from Lars' rival beat him up," Ronnie Anne answers.

Bebe continues to nurse him and makes him wear an arm sling. "You okay, Loki bear?"

"Absolutely fine, bae," Loki woozily answers, "Just feel alive seeing you."

Relieved on his safety, Bebe kisses him on the lips for more relief. Eventually, she notices the song number continuing. "Wait, who's singing?"

"Oh Lincoln got back on gear," Loni answers while dancing to the beat.

At that shocking revelation, Loki, Bebe and Ronnie Anne check out from the curtains onstage to see Lincoln and Clyde performing "Can't Stop the Feeling" and encouraging the others to dance. Also shocking to them is seeing the root of all their problems tonight, John, mindlessly participating to the crowd dancing.

And under the lights when everything goes
Nowhere to hide when I'm getting you close
When we move, well, you already know
So just imagine, just imagine, just imagine

Lars is still stunned at the turn of events. Despite seeing John submitting to the rhythm of an already infectious happy song, Lars remains cautious at the sneak attacks he might do.

While singing, Lincoln notices this and convinces his brother to join in with the dancing.

"Bro, this is out of our elements, much as John there. I will not sell my soul to move my body to a corny pop song from a corny kids movie," Lars explains.

Yet still, Lincoln drags him to the crowd who follow their every dance moves. Lars is initially unconvinced of his brother's persuasion, but slowly, he gives in to the groove and eventually dances along.

Nothing I can see but you when you dance, dance, dance
Feeling good, good, creeping up on you
So just dance, dance, dance, come on
All those things I shouldn't do
But you dance, dance, dance
And ain't nobody leaving soon, so keep dancing

I can't stop the feeling
So just dance, dance, dance
I can't stop the feeling
So just dance, dance, dance
I can't stop the feeling
So just dance, dance, dance
I can't stop the feeling
So keep dancing, come on

Lincoln and Clyde ultimately get up onstage for the final blow.

"Man, I never thought we would perform like this," Clyde shares.

"Yeah me too. And I almost think I have the voice of Justin Timberlake," Lincoln replies.

"Well said buddy. You think you lend these chops back on your own dimension?"

"We'll see. I still sing there, but not actually become a singer. That would be terrible."

"Right where you are. But who knows? Let's enjoy the moment."

With that, they continue on with the bridge.

I can't stop the, I can't stop the
I can't stop the, I can't stop the
I can't stop the feeling

The rest of the boys, with the exception of Levi, converge onstage.

"Hey guys!" Lincoln exclaims to them.

"Lincoln!" they reply loudly.

"Lincoln, you wouldn't believe what we just did! We took out those goons, one by one!" Lexx shares ecstatically.

"Yeah, and we cage them to a cart and drive them away, and like that, boom!" Leif adds.

"I wouldn't go on to the boom. But still, good!" Lincoln replies.

"Hey bro, thank you. Thank you for helping me overcome," Lars expresses his gratitude to his empathetic brother.

"I am always here for you, bro," Lincoln responds by making them do an improvised secret handshake.

Loki, Loni, Leon, Bebe and Ronnie Anne then follow along. "Lincoln!"

"Hey fellas!"

"Plan worked out perfectly," Loni replies.

"Loki, are you doing okay?"

"Just literally bumps on my body but doing good," Loki answers. "Can't believe you have grooves bro."

"Yeah us too," Ronnie Anne agrees, "So as romance, even though it's corny."

"Go on Lincoln," Bebe encourages him to continue with number.

And with that, Lincoln sways the audience of high schoolers, "Everybody on the dance floor, show your moves in 1, 2, 3, go!" and the Loud brothers, Clyde and the Santiago sisters lead them to dance, altogether onstage.

Nothing I can see but you when you dance, dance, dance
Feeling good, good, creeping up on you
So just dance, dance, dance, come on
All those things I shouldn't do
But you dance, dance, dance
And ain't nobody leaving soon, so keep dancing

With no delays stumbling on their way, the Real Boys perform their last number with enthused flair.

Everybody sing
Got this feeling in my body
Got this feeling in my body
Wanna see you move your body
Got this feeling in my body
Break it down
Got this feeling in my body
Can't stop the feeling
Got this feeling in my body, come on

After that, the audience gives The Real Boys a round of erupting applause and loud cheers from their peers. Some boys hoot, "Real Boys! Real Boys!" Some girls scream at the top of their lungs. While the rest throw their applause up in the air.

Lincoln is enthralled at this reception. He can only celebrate this unbelievable feat with a flip of his Matthew Healy hair and a smirk to his brothers.

The guidance counsellor host gets up onstage to wrap up their performance. "There you go, ladies and gentleman! Give it up for 'The Real Boys'!"

The crowd gives them a louder applause. In response, the boys and girls onstage give them a resounding bow altogether. And also, this signals them to retreat to the backstage for the next part of the plan.

As the guidance counsellor continues with his announcements, the gang vacates the backstage and heads out to the parking lot.

But expectedly, a recovered John and a bruised up Danny block their way.

"Well, well, well. Do you think you can get away that easily?" John interrogates them.

"John, will you stop this? It's pointless of you threatening us," Lars sways him.

"Do you think all of my work is pointless? You had my brother get stampeded. You got rid of our men. And you made me dance on a Justin Timberlake song. Now, you'll pay." John says while folding his sleeves to preparing beating Lars up.

"John!" someone eventually warns him, which turn out to be his girlfriend Sally, "Leave them alone!"

"Sally?" John turns to her and persuades her, "Sweetie, you supposed to be waiting at the parking lot. Let me take care of this."

"Stop this nonsense now or else," Sally warns.

"Or else what?"

"I'll be breaking up with you."

John tries to give out his excuses to justify his actions. "But Sally, they humiliated me…"

"So what? Then you are just going to turn against them?"

"What? No, of course not. Well, that goth classmate of ours really deserves a beating."

Suddenly, Sally slaps John's face, making everyone stunned at this feat.

"Sally? Wwwwwwhwhwhwhwhwat…?" John utters in disbelief, "I thought you promised not to hurt me. That was our vows."

At that distraction, the gang eventually escapes on a clean sweep.

"Well, you hurt my feelings right inside. It is done." And at that note, Sally walks away from John, who whines from this unbelievable turn of events. Danny aids him by his side, but John still cries like a baby.

The gang escapes via the fire exit backstage. But before they all escape, Sally catches up with Lars. "Hey, it was great seeing you perform."

"Thank you," Lars resolutely replies.

"Hey, take this with you." By her words, Sally kisses Lars on the cheek. "Take it as something to fulfill your night." After that, she walks away from the stage. In turn, Lars takes delight on this that he lets out a beam in response.

"Lars, aren't you coming?" Lynn asks him from behind.

"Hold on!" he utters back.
