Angry Luigi groaned getting out of his bed.
"I just wanted to see Atticus, but that will never happen." Angry Luigi says.
"That's your dream? Well, go! You gotta chase your dreams." Savannah says.
"No way, it's probably dangerous." Angry Luigi says.
Meanwhile, Mugman woke up. He then looked around. He rubbed the sleep from his eyes.
"Happy birthday, Mugman!" Kettle says.
"Elder Kettle?" Mugman asked tiredly. "Where am I?"
"The Inkwell Isles. You're home." Kettle says. He made Mugman his birthday pancakes.
Mugman smiled at this. He loved Elder Kettle's pancakes.
Meanwhile, Rosalina was reading when she sensed something.
"Oh, no…" She says. "I got a bad feeling…"
The Foxes were having a nice time relaxing, when something arrived to confront them.
"Is that us?" Luke asked.
"Yeah, they look like evil versions of us. Looks like we're in trouble." Emma says as the evil Luke tries punching Luke, who dodged. Alem tuber and his evil counterpart smirked and started fighting as Angry Luigi gulped.
"Why are you here?" Oliver asked.
"We're waiting for the world to burn." Evil Oliver says as they both shoot magic at each other.
"I have no time for this. I gotta find Atticus." Angry Luigi says, leaping over his evil counterpart, who shot Insanity's flames as Angry Luigi was sent flying.
"He mastered it?! We are screwed." Angry Luigi says as he is kicked aside.
The Foxes manage to subdue their evil counterparts as Luke knocks his evil counterpart out. They shot a magic blast, knocking out the evil Angry Luigi.
Alem tuber and his counterpart was tossing blow after blow and shooting blasts before Luke knocked out evil Alem tuber.
"That should do it. Well, Cuphead got what he wanted, a multiversal event. He better get ready." Alem tuber grumbled and grabbed his brother.
"We're going to stop the multiversal guests from going to Mugman's party." Alem tuber says.
"Wait for me!" Emma says.
"No, this is too big for you." Alem tuber says, dragging his brother around.
Meanwhile, Remy and the others were decorating for Mugman's birthday party.
"It has to be big." Remy says.
"For sure!" Stephen says. "I spent hours on his cake! I sure hope he likes 17 layers of chocolate, cookies & cream, and white chocolate…because that's exactly what I made!"
"And the flavored ice sculptures didn't make themselves." Lonnie says.
"It's gonna be a party to remember." Remy says with a smile.
With Mona, she was at work. She was determined to be off in time for Mugman's birthday celebration.
The whole town was decorating for the blue cup's celebration.
With Cuphead, Jitro sighed.
"That invitation brought the multiverse. This Is your fault." Jitro says. "Now your brother has to deal with that. He just wanted a nice birthday and you couldn't respect that. You never treated him with the respect he deserved. Now how to deal with the multiverse...that's it! Men, get the cosmic buddies they seem to travel through dimensions."
"What if they refuse?" Blaze asked.
"They won't." Jitro says.
His men go out to get the cosmic buddies.
Meanwhile, Mona was driving and saw Ashley blasting a demon with a barrage of spells and shrieking.
"What's going on?" Mona asked.
"Cuphead brought the multiverse and to think I was growing to admire him…" Ashley says, annoyed.
Jitro's men came.
"Fine, take the monster, sheesh…" She says
"We need you to come with us." One of them says as Mona was concerned.
"You need my help? Of course you 7do." Ashley sighed.
"Be safe." Mona says.
Later, Mugman and Mona were at the movies, seeing the new Dirk Dangerous movie.
"Mugsy, this guy looks awesome!" Mona says.
"I know!" Mugman says. "He likes to live dangerously!"
Meanwhile, Angry Luigi made a crystal sculpture.
"Brandy, look, realities are falling apart, gather your crew and meet me in my world. We need to stop this mess. I wonder what the writers will come up with. We all know how birthdays are the most important things in the world now and that Angry Luigi's channel just died." Delta says, breaking the 4th wall.
"No, we're not coming. Get the Smash fighters like Mario, Link, Kirby, and get some of the assist characters " Chrissy says.
"Hey, aren't we assist characters?" Ana asked
"Okay, we accept!" Kat says.
"Aren't you guys supposed to be heroes?" Oliver asked.
"Ugh, fine, we'll do it. Goodbye for good." Alem tuber says, getting to the ship.
"Yeah, no." Angry Luigi says as Alem tuber dragged him on the ship.
"Let's go. Who knows what monsters will come?" Jitro says as Bill sighed.
Meanwhile, Mona took Mugman to the mall.
"When is your birthday?" Mugman asked.
"I don't want you to worry about me." Mona says.
"I'd still like to know." Mugman says. "I'd like to treat you right."
"It's okay." Mona says, walking off to be alone. Mugman pitied her. Mona goes to an alleyway to cry hard.
"We're going on a space mission!" Kat and Ana say, packing their ninja tools.
Luke was rehearsing for the party with Shane.
"Crud, I just remembered it's Mona's birthday. She said she didn't want to upset Mugman and she'd forget her own birthday." Penny says.
"I think Mugman was willing to share with her." Shane says.
"That's sweet, them being birthday twins." Luke says
"I thought Mugman was done with sharing?" Lori asked.
"He does want to share with his beautiful Mona." Shane says.
Meanwhile, Alem tuber glared at Cuphead.
"You caused us to leave our home to fix your mistake. Why can't you do it?" He asked.
"Because he'll make it worse." Jitro says.
A few bounty hunters came in and tried to attack, but Ashley's wand glowed as her hair turned white and she shot a magic blast at one of their heads.
Kat leaped and slashed a few as Link stabbed some.
"Okay, if we're going to save the multiverse we're going to need help" Angry Luigi says.
Meanwhile they had to redecorate for Mona. Mugman had told them that he was willing to share with Mona. He was willing to make her happy.
"What kind of cake does Mona like?" Stephen asked.
"Vanilla." Penny says.
"I have the perfect vanilla cake!" Stephen said and dashed off to make it.
Luke smiled. "We're getting invited to the Chipettes' birthday this summer." Luke says as Savannah sent them the invitation for them to attend it.
Meanwhile, Mona sniffed.
"Hey, love. It's okay if you share a birthday with me." Mugman says. "I want to celebrate with you. Are you 17 today, too?"
She nodded.
"You deserve to be happy." Mugman tells Mona. "You are a gorgeous gem that must be admired."
Mona blushed and kissed Mugman.
Later, they arrived.
"Surprise!" Everyone says. Mugman smiled as Mona was stunned.
"What a wonderful surprise!" Mugman says, holding Mona's hands. Mona smiled a bit.
"Do you like it, love?" Mugman asked Mona.
She nodded, still stunned.
"What to do?" Mugman wondered as the party began.
Mona looks around, seeing the gifts and opens Penny's gift to see a new bike.
Mugman opened Luke's gift, which was a new pirate outfit. He grinned and put it on.
"Thanks, Luke, I love it!" Mugman says.
Mona opened her gift from Luke. It was a new faux fur jacket.
"Thanks, Luke, I just love it!" Mona says.
Mugman opens Shane's gift and sees three pairs of designer sunglasses.
"I love it!" Mugman says.
Later, Mona was eating pizza and thinking of the show.
"Mona, have you opened my gift?" Shane asked.
She opens it to reveal a new stage jacket.
"Shane, thank you!" Mona says.
Soon, it was time for Shane and Luke to do their show.
"First of all, can we wish Mona and Mugman a very happy birthday?" Shane says.
"Happy birthday!" Everyone says to Mona and Mugman.
Luke and Shane perform their song "California Man", their first collaboration song.
Everyone loved it as Mugman smiled.
Meanwhile, a lot of the multiversal guests were being stopped from coming.
"Done and done." Angry Luigi says. "You guys do what you need to do. I'll find Atticus."
Luke watches Mona and Mugman dance. He sheds tears.
Chalice sees this. Luke is now sobbing. The party stopped as everyone was concerned. Chalice sees Luke is lonely.
Lucy holds him as the dancing continues.
Later, Mona sat alone, thinking of her parents.
Meanwhile, Lucy goes to be alone when someone punches her, sending her flying as she was coughing. The figure revealed herself as Lynn.
"Lynn, you're back…" Lucy says.
"I'm not your Lynn, but I guess you're evil in this dimension." the alternate Lynn says as she rushed and started punching Lucy.
"I'm sorry." Lucy sniffed as Lynn kicked her.
Meanwhile, the party was going on as Mugman smiled at the ice sculptures Lonnie made.
"Try one!" Lonnie says with a smile.
Mugman tries a piece of one. "Mmmm! Blue raspberry! My favorite!" He says with a grin. "Mona! Come try a flavored ice sculpture!"
"Okay." Mona says and comes to try one. She liked the cherry and strawberry-flavored sculptures the most.
Later, Mona sobbed as Young Cricket pats her.
"Mona, what's wrong?" Penny asked, concerned for her friend.
"He has his Elder Kettle…" Mona sobbed.
"Oh, is it because he has a parent and you don't?" Penny asked. Mona nodded.
"Mona, my love, you could always stay with me." Mugman says as he holds her hands.
"No, I do have parents. But they never come home. My dad is an artist and my mom is a model." Mona sniffed. "But I'll take you up on your offer for tonight if that's okay."
"Of course." Mugman says. "I'll make sure you're comfortable and happy. You deserve to be treated right."
Mona smiles and kisses Mugman.
Ashley was blasting some monsters apart.
"That's the last of them" Tiff says as they were falling.
"We're going to die!" Tiff and Tuff say as the warp star saves them.
"See you crazy pokemon" Jason says waving as Pikachu and other pokemon leave to their dimension
"That was one crazy adventure." Sonic says.
"Poyo!" Kirby says as Mario gives a thumbs up. Shadow and Silver nod and walk off as Wario tries to get greedy, but Emila glares.
The Cosmic buddies arrive at the party to see Mugman hitting a pinata as Mona smiles at him.
Ashley sees Kettle hugging Mona as her hair turns white. She leaves as Red decides to go for the food.
"Oh, hey, Red, glad you could make it!" Mona says as Kat and Ana do an epic entrance.
"We saved the party!" Kat says as Ana giggled.
Mugman got his share of the candy.
"So, Red, I may be moving. It depends on what my parents decide." Mona says.
"That's cool. So, you're getting adopted?" Red asked.
"It's a possibility." Mona says.
"Boy, is Ashley going to be jealous…" Red says.
Later, Luke shows Mugman's highlight reel. Mugman was smiling at it as Mona held him close.
Stephen soon wheeled in the cakes he made. "Ta-da!" Stephen says with a smile. "Mugman, your cake is 17 layers of chocolate, cookies & cream, and white chocolate! And Mona, your cake was made with a Meyers family recipe for the perfect vanilla cake."
"Amazing!" They say. Mugman drooled slightly at the sight of his cake. Oliver lit the candles with Luke's help as everyone sang to Mona and Mugman.
After the singing, Mugman thinks of a wish and so does Mona.
Mugman wishes to have a better future and so does Mona. They then blew out their candles and smiled at each other as cheering ensued.
Later, as everyone helped themselves to the cakes, Mona gasped as her mother's limo came up.
"Is that your mom?" Mugman asked Mona, eating his third slice of cake.
She nodded. Mona's mom approached the couple.
"Mom?" Mona asked.
"Happy birthday, dear." She says.
"Thanks." Mona says before hugging her mom.
Soon, the party was coming to an end as Mona yawned.
Ashley spies, jealous of Mona. Mona then left with Mugman as she would stay the night with him.
"It's unfair that everyone has a happy family but me." Ashley says as Red gulped.
