On June 15th, Luna knocked on Luke's door, holding his half-birthday pancakes. She heard him sobbing.

She came in. "Happy Half-birthday, Luke!" Luna says. Luke looked at the slightly burned pancakes, then ate some.

"What's wrong? Do you want to talk about it?" Luna asked.

Luke pushes the rest of his breakfast aside, drinks every drop of milk in his cup, then goes off to shower.

Lucy had overheard Luke crying. "I probably failed him already." Lucy says. But Charity shook her head.

"Then why is he upset?" Lucy asked.

"He knows you and Luna remembered. But he has his doubts about everyone else remembering." Charity says.

Luan got Oliver his half-birthday breakfast. Oliver ate every bite.

Lucy glared, she only planned for Luke's party. She wanted Oliver to celebrate elsewhere or even on a different day.

Soon, Luke goes out to be alone. Just him. He did his things, then went to work on kingdom stuff with Chalice. Chalice could see he was feeling down.

"What's wrong?" Chalice asked.

"My siblings cannot be trusted. They don't want Luke to have his day." Luke says. "That's fine. That's just great!"

The siblings were decorating for Luke. "Everyone, it has to be perfect." Lucy says. "Or we die at the hands of Luke, the king of the Inkwell Isles."

They nod nervously.

At the castle, Luke gets showered with gifts from the kingdom. He smiled at this.

They got him toys and goodies, and even some white chocolate sculptures of himself.

"Amazing!" Luke says.

"Shall we go on the royal carriage, my lovely Lukey?" Chalice asked.

Luke nodded. They got on and rode through the town of Inkwell.

People cheered seeing Luke, who was smiling and waving to the crowd in his carriage.

They took pictures and videos as he smiled.

In Texas, things were starting to come together.

"Good. no one leaves until Luke says, don't eat any of the food before he does, make sure the attention is on Luke and Luke alone, Luke goes first for the piñata, and don't eat his cake." Lucy says, sounding nervous.

The cosmic buddies were having Oliver's party at the Mushroom Kingdom as Savannah planned it.

Soon Oliver arrived. "Surprise!" Everyone says. "Happy half-birthday, Oliver!" they say as Oliver smiles.

Luke sighed as he came back from his "kingdom celebration".

Lola finds him. "Hi, Lukey, I have a surprise for you." Lola says. She had a blindfold in hand.

Luke just stares at the ground. "I know the rest of you forgot." He says.

Lola sighed and put it on him, then she led him to the party. When they arrived, Luke sighed, taking off the blindfold as confetti rained down on him. Luke looked around as the guests, siblings and friends popped out.

"Happy half-birthday, Luke!" They say.

There were decorations, food and lots of gifts and crystal sculptures of Luke. Balloons on the walls and a bunch of golf courses, also arcade games Lisa made.

Luke smiled and opened Garrett's gift, seeing a new basketball and smiled. Chalice brought him a cool ring with a golf ball jewel. He grinned and put it on.

Leni made him a half-birthday suit. Mugman got Luke white chocolate boxes.

"This is amazing!" Luke says and opens Luna's gift seeing a new microphone.

Lola got him a throne and a crown. He smiled at this.

Luke opens Charity's gift, but doesn't see anything inside.

Luke hissed at his mother. "My own mother forgot…" Luke hissed.

"That's because your gift isn't in the box, cupcake." Charity says.

Luke looks for it, and when he finds it, he sees it's a whole new stage wardrobe designed by his favorite costume designer, Alina Golding.

Luke squealed. "Thank you, Mom!" Luke says. "This is wonderful!"

"Happy halfway to 20, my lovely little treasure!" Charity said to Luke as she hugged him.

Soon, Lola did a pageant performance for Luke. He clapped when she finished.

Luan does a comedy show, telling jokes. Luke laughs at them all.

Cuphead and Lucy go on stage and both play the piano. Luke loved this and clapped along.

They soon finish as Lucy reads a poem. He smiles at this.

Soon, Luke plays games with his friends as they have fun.

Then Chalice feeds Luke some pizza. After that, he goes to be alone. The others set up the golf course.

"Don't do anything without Luke." Lucy says.

Oliver was having a great time celebrating his half-birthday. Surrounded by family and friends, he was the center of attention and everyone was eager to celebrate with him. His wife Amber lovingly fed him cupcakes and other treats, while Emma enjoyed her own food nearby. Alem tuber watched with a smile on his face, crossing his arms as he observed the festivities.

The atmosphere was filled with laughter and joy as everyone shared stories and reminisced about past times. Oliver was in his element, smiling and laughing along with the others. He was clearly enjoying the attention and the celebration of his special day.

Meanwhile, Luke smiled as he beat Lori and Chalice at golf. He was definitely getting better at it. Luke then grabbed his golf bag and walked away.

"Is he OK?" Leni asked.

"He knows there's no happiness in the air at his party. He knows that Oliver is having the better party." Luna says.

"Which means we're doomed. You want me to measure your coffin sizes?" Lucy asked the siblings.

"Time for a golf game!" Oliver says

A few minutes later

"Mario, number one, he he!" Mario says as he leaped in mid air.

"Mario!" Bowser growled as Mario looked at Bowser. " Hello" Mario says

"You're having a party without me? Unacceptable!" Bowser growled.

"You know Mario can beat you, right?" Bill asked

"Not this time, this time he's going down and I don't care if Oliver gets in the way" Bowser says as Kamek used magic binding Oliver down.

"Mario it's just me and you, oh and my army." Bowser says as Alem tuber was beating up most of the army with Delta.

Mario looked at him "Let's a-go!" Mario says as Bowser tries to punch Mario as Mario leaped up.

"Showtime!" Bowser says and shoots flames as Mario dodges.

Meanwhile, Luke just sat outside and stared at the sky.

"Luke, there's more fun activities." Lisa says.

"Yeah, right…." Luke says sadly, looking at pictures from Oliver's party.

Lisa leads him back in and Luke gasps, seeing his favorite music stars.

"Y-You….You brought…." Luke just stood there in shock.

"Yep." Lisa says.

Luke was shocked to see Bruno Mars right there, on stage, in person. He also saw Laine Hardy and Brad Paisley. He couldn't believe it.

"Hello, everyone, where is the special half-birthday boy?" Bruno asked.

Luke comes up on stage, still shocked by all this.

"How would you like to perform with us?" Brad asked.

"Oh, wow! Sure!" Luke says, beaming. He performed "That's What I Like" with Bruno Mars, "Alcohol" with Brad Paisley, and "Other LA" with Laine Hardy.

Everyone was loving this as they recorded and took pictures.

Lynn brought out the piñata afterwards.

"Sweet!" Luke says.

Meanwhile, Bowser pants. "Okay, Bowser you're clearly beat and you're outnumbered." Daisy says

"I suggest you leave" Rosalina says but Bowser refused as Rosalina had no choice and opened a portal as Bowser looked down as he and his minions fell in the portal

"Awesome!" Alem tuber says

"Way to go!" Luigi says.

Oliver felt defenseless and sad.

With Luke, he was given his nine-iron and smiled as he smashed his piñata open. Candy spilled out as everyone took some.

"I can't believe you did that for me…" Luke says as Lisa smiles at him.

With Oliver, Rosalina untied him as Savannah got his piñata. Luigi was hiding behind Mario.

"Hey, the danger is over." Daisy says

Oliver looked down.

"Hey, no one is perfect." Peach says.

"That's not the point, okay?" Oliver says sadly.

"Hey, what's wrong?" Amber asked.

"One minute, it's a happy occasion. The next, it's interrupted! I think I was wrong to know that anyone was going to celebrate me!" Oliver cried.

"That happened to me, too." Peach says sadly.

"You know Luke hates it when his siblings don't show up to his events" Alem tuber says

"Hey, we tried to give you a party. It's not our fault." Jack says.

"Oh, right." Alem tuber says punching his brother in the face.

"Come, Oliver, I have a surprise for you" Amber says, taking him to Inkwell Isles and showing him a parade float. Oliver sniffed, unhappy. There was something, or someone, that was missing.

"You miss Luke and the cups, right?" Amber asked. Oliver began wailing.

"Happy half-birthday, son." Gabriel says as he comforts Oliver.

Meanwhile, at Luke's party, the lights went off as Luke looked nervous. He felt tears pricking his eyes.

It soon lit up to reveal a nice golf-themed 19 and a half layer cake with 19 and a half candles. He looked up at it, then looked down.

It said "Happy Half-birthday, Luke Flynn! You're almost 20!" It had golf-themed candles on it as well.

Leni had the camera as everyone began to sing. Luke could feel his tears falling from his eyes as he took it in.

"Luke, are you okay, what's wrong?" Lucy asked as she used magic, stopping the candles from melting as everyone looked concerned.

"I MISS HAVING MY PARTY WITH OLIVER, OKAY?!" Luke says as he bursts into tears and flees the room.

Lucy realized she made a mistake and texted Amber.

Luke was crying outside, planning to kill his siblings. He sobbed into his hands as he covered his face with them. He started to reminisce, looking back on all the birthdays he shared with Oliver. He felt happier then, celebrating and sharing the fun with him.

All he could do at this point was cry. He felt unhappy.

Soon, Amber came up with Oliver. "Happy half-birthday, Luke!" Amber says. Luke and Oliver hug.

They soon headed in and gasped as there were two 19 and a half layer cakes.

Oliver's cake was chocolate with emerald green icing and candles.

Everyone began to sing to them as they smile.

Oliver wishes for Gabriel to have a epic birthday in the future Luke does the same for his mother. Everyone cheered as they blew out the candles.

Soon, Lincoln played the ANH highlight reel Luke adores as everyone cheered and had cake.

Lucy planned Luna's anniversary.

"I have an anniversary?" Luna asked.

"The day our ex-father took you to see Mick. the day you became a rockstar." Lucy says as Luna looks down.

"My ex-father's dream, not mine…he forced that meeting for his idea of me. You think Luan liked pranks? No, that was him who got her into comedy. He got me into music and he got Lynn into sports." Luna began sobbing.

"I had no idea." Lucy says.

"I don't want to celebrate that!" Luna sobbed.

"We won't. What about me?" Lucy asked. "Were my skills natural?" Luna nodded.

"I'm so sorry you had to go through that, but I need to plan Mom's anniversary." Lucy says.

Charity was concerned for Luna.
