Savannah smiled on her birthday. It was May and university and school were ending soon. Prom at Greendale High and Fairway University would be the next day.
Sal was watching the news when they reported a robbery in Greendale. The Cosmic Buddies intervened and successfully stopped the robbery using their martial arts skills. They then proceeded to eliminate additional criminals who were hiding in the shadows. They leap away smirking.
"Honestly, I hope Emila gets better " Sabrina says.
"Me, too." Alex says.
At Fairway University, Luke and Mugman were finalizing everything for the Freshman Fling, the prom for all the freshmen at Fairway. Mugman and Luke were painting some Venice-themed scenery as Cuphead watched.
"What's the theme here?" Cuphead asked.
"Springtime In Venice." Mugman says.
"So amazing!" Oliver says, walking in with Beau, who was dressed head to toe in a gondolier costume as he was going to be one of the waiters at this prom.
Lisa smiled, getting ready for the science fair and hoping to win.
Lucy had still been missing, she was gone. But little does Luke know, she's going to turn up where he least expects it.
Chalice steps into the Fairway gym, gasping when she sees the decorating job Luke, Mugman, and Oliver did.
"This looks incredible!" Chalice says. "But some of the committee sent me because they're in a bind now…"
"Oh? And why is that?" Luke says.
"The DJ is double-booked, so he had to cancel." Chalice says. "Now there won't be any music to dance to…."
"Luna can play music." Mugman says.
"You called me?" Luna asked Mugman. Mugman explains everything, and Luna agrees to play music at the Freshman Fling.
Savannah smiled as she was going to celebrate, but Mr. and Mrs. Clusterfield were seen trying to rob a factory.
"Come on, let's get some payback!" Alem tuber says as Angry Luigi looks nervous.
They soon arrive. "Okay, it's payback time." Alem tuber says as Card Shark was there
"Oh, it's the Card Shark!" Jack says.
"The brats!" Mr. Clusterfield says.
Card Shark shot water at them as Angry Luigi was blasted down. Alem tuber leaped and punched Card Shark in the face and kicked him.
Card Shark growled and made water shark constructs.
"Oh, crud…" Jack says.
"We may be in trouble." Alem tuber says as Card Shark smirks.
Angry Luigi groaned as the Cosmic buddies got ready.
"Wait, I hate water!" Delta hissed.
Chrissy turned into Big Chill and shot ice at the sharks.
Mr. and Mrs. Clusterfield drove away as Delta glared. She curled into a ball, but Card Shark blasted her.
Angry Luigi turned into Cannonbolt and rolled after the Clusterfields as he gave chase. Savannah followed Cannonbolt.
Card Shark tries punching Big Chill who flew away as Alem tuber leaped and punched Card Shark as Alex rushed in and attacked Card Shark.
Cannonbolt turned into XLR8 and went faster before missiles hit him, causing explosions. Angry Luigi fell hard into the place where the next show would be at.
Savannah launched herself with the Plunge-it as she slammed it on the limo and holds on to the handle and shrieked as the car was moving, taking her with it. Card Shark used smoke bombs as the heroes fell asleep.
Savannah woke up as they were all tied up.
Meanwhile, the others were finished as Luna smiled.
"Good job!" Luna says.
Luke smiled.
Meanwhile Emma called Jitro and his men but they hung up on her. Emma called Jason.
Jason was at home and was now concerned as he met up with Emma. "Let's kick butt!" Emma says.
They sneak into the base. "Okay, let's do this" Emma says as Guards glared.
Skylia sensed this and realized her kids were in trouble and decided to save them.
She snuck in and sees them making plans to kidnap Luke and use his powers to rule the earth.
"Hey, let us out! Or else!" Delta says
"Or else what?" Big Owl asked.
Suddenly, magic balls hit him as Emila arrived furiously.
Skylia was Surprised as Emila used a spell to free them as the Cosmic buddies smirk.
"Too late, we already have plans to kidnap Luke, Cosmic losers." Mrs. Clusterfield says.
"Looking for me?!" Luke says, flying in with Oliver next to him. "You aren't using me for ANYTHING!" Luke says.
"We're not Cosmic losers, it's Cosmic Buddies." Jason says.
Card Shark shot water, blasting Luke down as Alem tuber punched Mr. Clusterfield down. Chrissy leaped and turned into Wildvine and used vines on Big Owl while Delta and Oliver took out guards.
Angry Luigi stomped on Card Shark. "Time for my Elemental Storm!" Angry Luigi says as he tries to do it, but couldn't memorize the chant. He ended up zapping himself.
Angry Luigi sighed and put a fire flower in his Omnitrix, turning into Fire Rath.
"Here comes Rath!" Fire Rath says and uses fire slashes, only to be blasted with water.
Alem tuber was punching Mr. Clusterfield as he smirked.
"Okay, let's end this." Savannah says as she and Bill mess with the controls.
Luke hissed as Card Shark tried punching him, who leaped and kicked him down. Two guards tried to shoot him as he leaped and kicked them down. Oliver used magic to slam guards down.
Card Shark makes water sharks. Luke freezes them and breaks the ice sharks. He then uses his Lightning Lariat to tie up Card Shark after punching him and knocking him out cold.
As for the Clusterfields, their plans were burned by Oliver as well as their backup plans. Oliver then took them away after making sure they didn't wake up until he got them to the high-security prison.
Big Owl knocked Chrissy back as Chrissy shot plasma waves as he flew up.
"I got this." Delta says.
The cup trio sees this fight going on and they help out.
Delta spin dashed into Big Owl and clapped her hands.
"Okay, let's bail!" Bill says as a helicopter leaves.
"And there goes Anti-Hybrid. Eh, we'll get him another time." Bill says as they head to celebrate Savannah.
There were decorations everywhere at the local park as Savannah's party got underway.
Luke and Oliver were with the cup trio at the ice cream shop. Mugman got his ice cream as his mind wandered.
"Is it true? You 5 were the ones who stopped those villains?" A fan asked.
"Yep! All 5 of us!" Oliver says.
The cosmic buddies see this on the news.
"They didn't mention us." Alem tuber says as Emila sighed.
"Okay, happy birthday, Savannah!" Jason says as Savannah smiles, seeing food.
With Mugman, something was clearly on his mind. The other four noticed.
"What is it?" Luke asked.
"I am going to ask Margo to marry me." Mugman says.
Everyone cheered for Mugman, who blushed a little. His brother smiled at him.
Meanwhile, at Savannah's birthday party.
"Our highlight reel consists of our greatest moments." Angry Luigi says as he shows it.
There was footage of them performing on stage as Savannah smiled.
Soon, she opened gifts. Angry Luigi got her some hair accessories. Emila got her some new shoes.
Savannah pulled Angry Luigi on the dance floor as Angry Luigi looked nervous.
Cuphead later crashed Savannah's party as he heard the cake was cool.
"Cake!" Cuphead says and had some of the cake as Savannah tried to be as nice to him as possible.
Chalice came to get Cuphead.
"You can stay." Savannah says to Cuphead.
"Yippee!" he says. The party had fun games, which everyone enjoyed, then everyone else got to have cake.
Later, Cuphead went home. He had fallen in love with Lucy and planned to propose to her someday. Right now, he was happy that his brother was going to ask Margo to marry him.
