Where we last off, Mario and his friends parted ways after driving out the evil demon Abigor and his monsters invading the Nintendo Skyscraper. Everyone thought all's well that ends well…

until Mario returned to his apartment to find his beloved Princess Peach turned into a zombie! It seems that Abigor did NOT try to make her smitten with Wario (who is long gone by now) as promised but rather cursed her into one of the walking dead!

Mario quickly rushes to Kirby and Link's room and knocks loudly. They have since woken up from their nap and are watching horror movies on TV (since that's the only thing that's on.)

"I'll get it!" says Kirby. But as soon as he is about to open the door, Mario gives up knocking and opens the door himself. This squashes the poor little puffball flat. "Owie!" he squealed.

Ignoring Kirby, Mario announces, "I-a have some very important news!"

Link responds by grabbing an air pump to reinflate his pancake-shaped friend.

"What's up?" Kirby asked after becoming three-dimensional again.

"So when I–a went back to Peach's and my apartment, you'll never-a guess what I found. Princess-a…Peach…has-a been turned into…"

Mario's friends brace themselves for the what he'll say.

"A ZOMBIE!"

Link and Kirby fall to the ground.

"But…how?" Kirby asks as Mario helped them up.

"Well…remember-a Wario's part of the deal? That Peach would-a fall in love with him and not me? Well…I think he lived up to his part of the bargain…at least sort of. He didn't-a brainwash her to leave me for him, he-a erased all her memories of me, and then cursed her to be a zombie!"

But when Mario and his friends return to Mario's apartment, Peach is gone! All that's left was…

"A golden die?" Mario says, confused. "She was in here just a little while ago!"

Mario picks it up curiously.

"Somehow I-a get the feeling I've-a seen this thing before. Check it out, the die can be opened and rearranged. I wonder what happens if I rearrange it THIS way…"

As Mario rearranged the cube, everyone begins to feel dizzy and nauseous. So Mario stops.

"Glad that's-a over!" Mario says.

"Strange…nothing has changed…" Kirby says quizzically.

"Let's look around," Mario suggests.

"Search all rooms!" Kirby adds.

The trio split up. Kirby runs into the bathroom, Mario the kitchen, and Link the living room.

"Oh, a bathroom! I wanted to wash my flippers anyway…" Kirby thought.

Suddenly, the toilet vaccumes Kirby in, not unlike Kirby himself.

"I'M BEING SUCKED IN! HEEEEEEEEELP!"

Mario checks the fridge. It then does the same to Mario.

"LET-A ME GO!"

Link checks the living room couch when he suffers the same fate to the TV.

"AARRRGHHHH!"

"WHAT'S HAPPENING TO US?" Mario and Kirby scream, as they and Link get swallowed by a void.

Mario lands straight on his head.

"That-a hurt hard!" He rubs his head and looks around as Link and Kirby got up. "Where…where are we?"

It looks like some sort of crypt. There were graves everywhere! Like in a horror movie!

"We're-a alone, scared! I'm-a afraid we're in…the Underwhere!" Mario says worriedly.

"Look t-t-t-there! Near that grave there's a bony hand! It's holding a book! C'mon, grab it!" Kirby pointed out.

Mario retrieves it and opened it. "Hm…it-a seems this is a magic book. It-a may come in handy!"

Mario flips through the pages and chants a spell to test it out. "Dienstmädchen verwandeln!"

Mario and friends are zapped by a flash of light, and they were wearing wigs and maid outfits!

"What the heck?" Mario exclaims. "This is-a the wrong spell! I'll-a try this one instead. Sesam öffne dich!"

A gate hatch opens with a creek.

"The door!" Kirby says. "It opened!"

Mario, Link and Kirby walk through. The only sounds they hear are water dripping.

"Mama mia!" Mario sighed. "This isn't-a much better than the graveyard."

"I can barely walk in these high heels!" Kirby complained. "I want to go back to Dream Land!"

"This is Dream Land…" a demonic voice said. "Or should I say…Nightmare Land!"

"WHOA!" Mario said, almost losing his balance.

The voice belonged to one of Abigor's minions, accompanied by Chucky. "Who are you?" Chucky demanded. "And what brings you to the Elm Street Tunnel?"

"We're-a…we're Abigor's maids! We're-a ready to make Abigor's room squeaky clean again!" Mario said hesitatingly.

"Then go right here. After you!" Abigor's minion said, surprisingly politely. As soon as they opened the door, he kicked them in. "Welcome to Abigor's temple, Infernum!"

They were in a circular arena with a star marking on it. There was crowds of monsters watching. They heard a familiar voice…

"Greetingsssssssss! Whyyyy, ifff, ittt isn'ttttt Marioooooo, Linkkkkk, andddd Kirbyyyyyy, notoriousssssssss mugsssss offf theeee videoooooo gameeeee sceneeeeeee! Welcomeeeeeeee tooo theeee Underwhereeeeeeeeeee! I ammm Abigorrrrrrr! Snoopinggggggggg asss usuallllll forrrr Peachhhhhh, I seeeee, Marioooooo? Greatttttt plan, but your mission ends here! Commmme onnn, guysssss, getttt himmmm!"

They were ambused by a horde of monsters. They shoved Mario and friends around like a bunch of people cutting in line at the fair.

"Mario!" Kirby shouted. "The spellbook! Read from the spellbook!"

"Okay! Follow-a me! We-a have to stay together!"

The trio shuffled themselves through the crowd and finally found a small space in the crowd that wasn't occupied with monsters.

Mario quickly flipped through the spellbook. "Dingelchenzauber, Schubberfluch, Fellfroschmutation...Ah! The Düster-Helden-Horror spell! That's it!"

No sooner said than done! Shortly after Mario utters the magic formula, our three friends transform into the Hellish Triumvirate!

Mario becomes a wizard with green skin, a nosering, and a giant sledgehammer. Link becomes a wolf with a thirst for blood. And Kirby gains cobalt armor with a belt and a chain.

Although the monsters still put up a fight, bombarding them with tanks, missiles, and bones, the Hellish Triumvirate will never give up!

"Party…

Mario pounds his hammer into a slimy red monster, and Kirby swings zombies, feral hogs, and werewolves around with his chain! Link bites the lights out of hundreds of demons.

in the Underwhere!"

The monsters were left in the dust while Mario and co. rejoiced.

"Abigor! They kicked our butts! I'm scared of them…"

"Alright, let's get outta here! But mark my words, I'll be back!"

They all left in a skull-shaped puff of smoke.

The three friends stood at the now-empty arena. There was a door right in front of them.

Mario went up to the door and motioned for Link and Kirby to follow.

They shook their heads. "Mario, I think you should do it," Kirby said. "She's yours. Go get her!"

With that, Mario burst open the door while Link and Kirby watched.

"Princess-a Peach, your savior is-a here!" The room was empty except for a green wall and a luxorious, pink bed. On it sat Peach, still a zombie.

"At last! Princess-a Peach! I've saved you!"

"Your mother scrubs toilets in the Underwhere…" Peach said in a monotone voice.

"What are you-a saying, dear? You-a must be possessed! But…but…"

"My-a love for you is stronger than this curse!"

And with that, Mario kisses ker. Kirby blushes and covered his eyes, while Link stands paralyzed in shock from Mario kissing a zombie.

Mario opens his eyes.

"It…it-a didn't work…" Mario says sadly. He goes back to the group with Peach in his arms. She is silent and unresponsive.

"I'm so sorry about your girlfriend, Mario. She really loved you, you know," Kirby reassures Mario.

Link nods sincerely.

"W-who's-a going to rule the Mushroom Kingdom without her? She doesn't-a have any direct relatives…" Mario asks.

"We'll think about that later…but right now, let's be happy we're together. Think about it…Abigor could've beaten us up!" Kirby replies.

"U-Understood."

Mario, Link and Kirby come in for a group hug. The war against the Underwhere is over…

Then, Peach's pale face fades, and she opens her eyes, still in Mario's arms.

"Mario…"

The three gasp with astonishment, especially Mario! Peach smiles hugely.

"Mario, my savior! Hold me tight and never desert me again!"

Mario returns the smile.

"I-a promise! Nothing can-a separate us again!" Mario vows.

He carries her back to where Link and Kirby were.

"Who are those guys?" Peach points curiously to Link and Kirby.

"Princess-a Peach, allow me to introduce you to-a Kirby from Dream Land, and-a Link from Hyrule!"

Peach shakes hands with them both.

"All that we-a need now is a way to get home!" Mario explained.

"Yeah, you're right," Peach says. "What IS this place anyway?"

"Promise you won't freak out?" Kirby says. "We're in Infernum, a temple in the Underwhere."

"The Underwhere?" Peach puts her glove over her mouth. "You mean the place where video game characters go when they…get a Game Over?"

"The one and only."

Mario stops flipping through the spellbook. "Ah, here! I found the spell to get out of here! Es gibt keinen Ort wie zu Hause!"

The quartet is zapped, and they fall right on top of a table at some sort of party!

"Hey there! Happy Halloween!" a bearded, masked man says. Mario screams loudly.

"Where the heck are we?" asked Kirby.

They looked around. There was a band on stage, people in costumes from pirates to cavemen to muscular guys, a pig being roasted, performers on stage, people clinking drinks; there was everything. Link and Kirby soon became immersed in the fun.

"Wow! I've seen these kinds of parties on TV, but never in person! They say they'll rot your brain, but who cares?" Kirby says, enjoying himself. "Mario, over here! You're missing the party!"

Mario sat out with Peach, sneering at the party. "I don't know where we are…but one thing is for sure…it's worse than the Underwhere!" Mario said.
