(This is all taking place a year after Lane's 15th birthday.)

It was a nice March day. Unlike his female counterpart, Lukas wasn't as loud in the mornings. He preferred to save his loud guitar and instrument playing for later in the day, out of respect for his siblings.

There was a knock on his door. Lane came in with his birthday breakfast.

"Awww, thanks, bro! This looks righteous! I love sunny-side-up eggs!" Lukas says.

"No problem." Lane says.

Meanwhile, Luna wakes up in a sad mood.

"Did they forget?" Luna asked herself as there was a knock on her door.

"Who is it?" Luna asked.

"It's a woody day! Or should I say, cakey day!" Luan jokes, coming in with Lincoln, holding Luna's birthday breakfast. The rocker girl smiles at the root beer float-flavored pancakes and scrambled eggs.

"This is sweet! Thanks, you two!" Luna says.

"No problem!" Lincoln says.

After breakfast, the two of them get ready for the day and leave to visit their respective friends. Luna was with the Moon Goats while Lukas was with his band.

Back at home, the other siblings prepare a Sweet 16 party for them.

Lori smiled at this. The siblings even got them gifts. But soon, the party setup began to fall apart as the younger siblings started fighting.

"Stop it!" Lori says to them as she and Loki put an end to it. The decorations and all were in complete shambles.

"Look at what you all have done!" Loki says as they look around.

Luna looked annoyed, seeing this as her eye twitched. Lukas was doing the same thing.

"So, this is how we're going to remember our 16th birthday…" Luna says.

"BY SEEING OUR SIBLINGS GET IN A HUGE FIGHT!" Lukas says.

They leave the house.

Lisa and Levi use their robots to help fix the mess. Rita was scolding the rest of the siblings.

"How could you?!" Rita says to the younger siblings. "No TV for a week!" She says.

The younger siblings look ashamed.

Luna and Lukas sighed sadly.

Later, they get texts to head to a restaurant with a dance floor. They arrive to see decorations, gifts, and their siblings.

"Surprise! Happy Sweet 16, Luna and Lukas!" Everyone says.

The two rockers are very surprised by this.

They look around at everything. There were rock & roll decorations and a pile of gifts for them both.

"Wow!" they say.

They soon open Luan and Lane's gifts first.

"Guitars? That's rad!" Lukas says.

"Amazing! Thank you!" Luna says.

They then open Lincoln and Linka's gifts. Lincoln and Linka made some rad drawings of them

"Thanks Linc, it's amazing " Luna says

Leni and Loni made them new clothes.

Lucy and Lars read some poems.

Later, Luan and Lane juggled for them as other people were there. Pop-Pop then showed up.

"Pop-Pop!" Lukas and Luna say, smiling.

"Hey, kiddos, happy 16th birthday!" he says, giving them $300 gift cards to the music store.

"Thanks Pop-Pop." they say.

Lola and her counterpart do a dual pageant show for them, loving the rock & roll theme of it.

"Way to go, sis." Luna says. Lola smiled.

Soon everyone was eating as Lincoln was happy for his sister and brother.

Lincoln then looks at the 4th wall. "See, guys? No matter how things look, the Louds stick together."

"We'll be all right." Linka says.

Rita arrived with birthday cakes for Luna and Lukas, bringing smiles to the siblings' faces. The cakes were beautifully decorated with colorful frosting and topped with 16 candles on them both. Luna's cake was chocolate with vanilla filling, while Lukas' cake was vanilla with chocolate filling.

As they blew out their candles, Rita and the others sang "Happy Birthday" to them. The siblings were overjoyed and thanked Rita for the delicious cakes. They spent the rest of the day celebrating with their family and friends, enjoying the treats, and playing games.

The next day Lucy and Lars was washing the dishes.

"Lars, want to work on some blood?" Lucy asked

"Yeah." Lars says as they go to do so.

Linka looked on before deciding to watch some TV.

"Hey, Linka." Lars says, scaring her.

"What?" She asked.

"We wanted to go to the store to buy supplies, but Lola ruined it." Lars says as suddenly Lincoln was being manhandled by Girl Lynn.

"Leave him alone!" Linka says.

Lola kicked Lexx as Luna and Luan was at it again.

"Todd, tell my siblings I wish for this madness to end." Lisa says. Levi nods in agreement.

Lynn Sr. tries to get control, but Loki shrugged while texting. Lynn Sr. then ran to take cover in his room.

Lori then appeared in her military uniform.

The siblings froze in terror as they looked at her.

"What's wrong with you all?!" Lori asked. "What is going on here?!"

They point at each other, trying to explain.

"He/She started it!" They say.

"Lynn assaulted me!" Lincoln says.

Lori glares at Girl Lynn.

"It's our thing." Girl Lynn says.

"Lori, we need a ride to get supplies." Lucy says

"Yeah." Lars says as Loki gets off his phone.

Lori gives them a ride.

Later, Rita came back and saw what had happened. Those responsible had to clean up their messes. Lincoln and Linka sighed.
