WARNING: Certain details within Mario series canon have been altered. Things like making goombas a bit more anthropomorphic than usual. This is just how goombas shall appear in Ooo. If you prefer, simply consider any mention of goombas with arms to be referring to that mysterious force that allows them to hold things without having them. Also, the Bowser side plot will be removed as the only character that would fit the role (With Finn as Mario and PB as PP) is Ice King, but he's way too "Comic Relief" to play the role of a "Remorseless King of Evil."

Please do not kill me for any changes you may not agree with.


More Prologue - A Rogue's Welcome

"Yo, Finn, wake up bro. We're here!"

Finn opened his eyes to see the town of Rogueport off in the distance. It remained there, in the distance, for some time. Finally, Finn asked "Why aren't we getting any closer?"

"You're sure you want to Rogueport, then?" the boat's pilot asked, "I did tell you the various sordid stories about the place, right?"

"Of course we do, Princess Bubblegum is waiting for us! And we're heroes, so there's nothing that goes on in that town that we wouldn't be able to handle," Finn replied.

"You say a princess is waiting for you?" the pilot asked, clearly not believing them. "Well, anyway, if you insist…"

As soon as they were off the boat, it sped out of the harbor as fast as it was legally allowed to.

The Rogueport docks were staffed by an eclectic mix of mushroom folk, rodent folk, and, perhaps most oddly, sentient bombs.

"Do you see PB anywhere, bro?" Jake asked.

"Maybe she's waiting for us in town somewhere," Finn replied, "Let's just look around."

Jake hopped into Finn's backpack, and the two started off, but then stopped as something ahead of them was causing a commotion.

A young mushroom girl, dressed in a duster coat over the stereotypical schoolgirl outfit, was being chased by a group of costumed thugs. "Get away from me, you creeps! I have nothing to say to you!" She yelled.

"Oh, give it up, girly! I know you were asking around about the Mystic- uh- thingies… Anyway, you're gonna tell us everything you know!" the biggest one (And therefore, the one in charge) yelled back.

"I wouldn't tell you anything even if you asked nicely!" she responded.

"Oh, we'll see about that, little girl." The big thug turned to his minions and said, "Grab her, boys! We're taking her back to the fortress for interrogation!"

The two smaller thugs saluted him. "Yes sir, Lord Crump!"

The girl backed away as they approached her. "S-stay back! I'll scream, I swear!"

"Buh-huh-hah! Look around, girly! You're in the wrong town if you think anybody's gonna come save you!" Lord Crump yelled.

"Dude, we have to help her!" Finn whispered to Jake.

"You just wanna help her 'cuz you think she's cute," Jake replied.

Finn blushed profusely. "No!"

Jake raised an eyebrow.

"Okay, yeah, but that's not the only reason! What kind of heroes would we be if we didn't help her?"

"Point. Let's do this!"

Finn charged in to the rescue. As he approached, he gave a slight nod to the girl, who proceeded to duck behind him.

"Oh, thank Glob!" She said.

"Oh, come on!" Lord Crump shouted, "The one time there's a hero in town, and he's there when I need to kidnap someone!" He cracked his knuckles. "Well, it looks like I'll also be adding murder to my list of crimes committed today."

Finn brandished his trusty golden sword. "Yeah, not happening, dude. I'm too awesome to die here," he said. And then his eyes went wide as he narrowly dodged a flying body press.

"Get him, hero! You can do it! You just gotta hit him a bunch!" the girl cheered.

Finn charged at his foe and slashed hard, cutting a large gash in Lord Crump's suit.

"YOU RUINED MY SUIT! HOW DARE YOU?!" Lord Crump cried. "BOYS! GET HIM!"

Suddenly, the area was flooded with those costumed weirdoes, who all immediately jumped at our heroes. Fortunately, they were too busy bouncing off of each other to realize they weren't hitting any of them.

"Quick, this way!" The girl called, and she and Finn slipped out through a conspicuously open spot in their enemies' attack pattern.

The costumed idiots continued their attack for several minutes before finally Lord Crump realized something was amiss. "HOLD IT!"

They all stopped their attack, and it suddenly became clear what was wrong.

"They got away?! Motherlumping- AAAAAAAAARGH! That little- He's gonna pay for ruining my favorite uniform!"


Meanwhile, in an alley somewhere in Rogueport, our heroes stopped to catch their breath.

"-whew- I think we lost them," the mushroom girl said. "Anyway, thanks for that, back there. You really are a hero."

Finn blushed, "Heh, It was nothing. Y'know, just doing what heroes do."

"Well, you totally deserve a reward!" And with that, she gave him a kiss on the cheek, which only served to intensify his blushing.

"Uh, so, I guess introductions are in order," Finn said after he managed to calm down enough to form coherent sentences again. "I'm Finn, and this is my bro Jake."

Jake poked his head out of Finn's backpack. "Yo!"

"You don't look like a dog, though," the girl pointed out.

"We get that a lot. Finn here's adopted, actually," Jake explained, patting Finn on the head. "Still, I couldn't have asked for a better brother."

"And you are?" Finn asked.

"Oh, right! My name's Goombella. It's a pleasure to meet you both," said the girl, "In case you don't know, I'm a goomba, one of the varieties of mushroom folk native to the Mushroom Kingdom."

"So, why were those weird costumed jerks chasing you?" Finn asked.

"I guess it's because they were after the research I've been doing in town, see, I'm here on an internship with my archeology professor, and we're studying the legends surrounding this town," Goombella explained, "Which, by the way, if it weren't for the fact one of those legends involves some kind of treasure, we'd probably be long gone from this toilet of a town by now."

"Wait, treasure?" Finn asked, "That's actually kind of interesting, 'cuz we're here about a treasure hunt, too."

Jake dug around in Finn's backpack and popped out with the map in hand. "Check it! We got a treasure map and everything."

Goombella's eyes widened. "Oh my Glob! Let me see that!" she cried, grabbing the map from Jake's hands. "This is- Is it? Could it really be…?" She grabbed Finn by the shoulders and shook him. "TELL ME WHERE YOU GOT THIS!"

"We- We got it from Princess Bubblegum. She sent it to us and told us to meet her here."

"Why if it isn't Finn and Jake!" a new voice called. The voice, as you might have guessed, belonged to Peppermint Butler. "What brings you two out here? And by the way, have you seen the princess recently? We got separated, and now I can't seem to find her anywhere."

"Wait what? PB is missing?" Finn asked, "What might have happened to her?"

"You don't think she got kidnapped, bro?" asked Jake.

"Naw, Prubs is way too awesome to get kidnapped nowadays," Finn replied.

"Yeah, that can't possibly be what happened," Jake agreed.

"Oh, well. If you find out anything about what happened, you can find me at the inn on the town square. I recommend staying there if you end up needing a rest yourselves." And with that, Pepbut walked off.

The three of them stood in silence for a moment, before Goombella spoke up. "You know, there's a chance we're all after the same treasure. If that's actually the case, then maybe my professor might know something about your princess friend. His name's Dr. Frankly, and he's currently set up over in the slums. Come on, I'll take you there."


A/N: This feels like a good place to stop for now. Tune in next chapter for the rest of the Prologue, where we'll meet Dr. Frankly, Finn and Jake learn about Action Commands, and the quest for the "Mystic Thingies" begins!
