While Kim & Mabel were having their little misadventure in the Skull Fracture, Ron & Dipper had arrived at the jail. Since they were waiting for the girls to return, Ron had asked Dipper about things in Gravity Falls.

"You're telling me you actually have a Halloween in summer?" he asked "oh man, that is awesome!"

"It certainly was a unique experience, that's for sure," Dipper told him.

"Halloween is like, one of all my time favorite holidays," Ron told him "last year, Kim and I did our first costumes as a couple," he added, pulling out a photo from his pants that showed the two dressed as Anna & Kristoff from Frozen.

"So, you just carry that picture around with you all the time, huh?" Dipper asked.

Ron didn't have a chance to answer before Mabel & Kim finally arrived back on the scene.

"What happened?" he asked.

"I got into a little trouble, so Mabel started a bar fight," Kim told him "no big."

"I saved the day Dipper, I'm a hero!" Mabel said happily.

"You caused surly drunk guys to fight each other, that's not exactly heroic," Dipper said.

"Why can't you let me have this?" Mabel asked.

"With any luck, we've at least slowed Drakken down," Kim said "now let's visit this Gideon kid and see if he can shine any light on what's going on."


A few minutes later, the five gathered in one of the visiting areas of the jail.

"I can't believe the cops actually agreed to this," Kim said.

"You apparently haven't met Sheriff Blubs," Dipper told her.

Kim didn't have time to ask what he meant, as a familiar chubby & pompadoured face appeared behind the glass divider.

"Why Dipper Pines, so nice to see you," Gideon said in his usual Southern accent "and Mabel, my dear, always a pleasure."

"Not for me," Mabel replied "if there wasn't a window between us, you'd so be getting a face full of spit!"

Gideon chuckled "ah, charming as always my little desert flower. And pray tell, who are your guests?"

"I'm Kim Possible, and this is Ron Stoppable & Rufus," Kim explained.

"Oh yes, the famous teen hero," Gideon told her "to what do I owe the pleasure of y'all paying me a visit here?"

"Cut the nice guy act Gideon," Dipper said.

Gideon narrowed his eyes "very well then," he replied, in a more sinister sounding tone "I suppose you're here about some recent e-mails I exchanged with a delightful new friend I found online."

"I'm surprised they let you use the Internet in prison," Dipper commented.

"Oh indeed, they feel that communication with the outside world is helpful in rehabilitation," Gideon replied "imagine my surprise when I discovered someone whose interest in ancient artifacts nearly equaled my own."

"Monkey Fist," Kim replied "and, exactly what ancient artifacts was he interested in?"

"Oh, quite a number of them," Gideon continued "he was quite delighted when I informed him of all the wonderful mystical things that could be found here. However, there was one in particular that seemed to pique his curiosity; the Mask of Magorga."

"The who of whatsit?" Mabel asked.

"The Mask of Magorga; legend has it that whoever possess the mask can enslave the minds of those they look at."

"Terrific, another mind control scam," Kim replied "and where exactly is this mask?"

"Hidden somewhere in the mountains," Gideon told her "I thought of looking for it myself, but I couldn't."

"Cause you're in jail?"

"Oh no Miss Possible; you see, the mask was locked away years ago due to how dangerous it is. However, if one were to locate a special amulet, it would help to unlock the mask's location. Despite my best efforts, I was never able to locate the amulet, so I switched over to other pursuits instead."

"So, no problem, right?" Ron asked "if creepy kid here couldn't find the amulet, then that probably means Monkey Fist & Drakken can't either."

"They wouldn't have come here if they didn't have some idea where it is," Kim told him, before turning her attention back to Gideon "you don't seem to have any trouble telling us all about this.

"That's because, my dear Miss Possible, it doesn't matter if you know, because there is absolutely nothing you can do to stop it."

"Yeah, if you've heard of me, then you've probably also heard my motto 'I can do anything,'" Kim replied "including finding a hidden mask."

"Oh, I doubt that very much Miss Possible," Gideon told her "even now, I'm sure Mr. Fist is coming closer to finding the amulet, and the mask. And with it, he shall enslave everyone in this accursed town, serving as my proxy for vengeance against all of them for putting me here!" he replied angrily before checking his watch "well, it's almost time for lunch, I don't wish to miss that," he replied in a calm voice "nice seeing you again Dipper, don't be a stranger okay?"

"I do not like that kid," Ron said, as Gideon was escorted back to his cell.

"Me neither," Kim replied "but I like the idea of Drakken & Monkey Fist in possession of a mind control mask even worse. Come on, we'd better get back."


Unknown to Kim, as they were visiting Gideon, a special someone was paying a visit to the Mystery Shack.

"Welcome to the Mystery Shack, popular tourist trap and recent hotel" Stan said "care for a room?"

"Yeah uh huh no thanks," Shego told him "I'm just browsing."

"Are you sure? I can offer a discount for a pretty lady such as yourself," Stan said, as charming as he could muster "not too much of one, but still."

"Oh yeah, so sure," Shego replied.

"Well if you change your mind, I'll be in the back room," Stan told her, giving her his best grin.

After he left, Shego began searching the shack, before she stumbled upon the parlor.

"Bingo" she said, and took something out of her bodysuit, affixing it to a nearby table "now to get out of here before that old creep comes back," she commented.


So, unaware of what just happened, the group eventually arrived back at the Shack, where Stan was in the middle of talking with local reporter Toby Determined.

"I want you to put a nice ad promoting my hotel in the Gravity Falls Gossiper," Stan said "an ad like that oughta get the guests coming in"

"And what do I get if I do?"

"I'll give you 15% off of the price of a room," Stan told him "no, scratch that, 10%. Aww what the heck, I'm feeling generous; I'll go as high as 5%" he added.

"Ordinarily, I'd turn that down, but one of your hotel rooms is probably better than the mattress I sleep on now, so you got a deal," Toby said, shaking Stan's hand.

"You won't regret this Toby," Stan said as the reporter walked off "creepy little troll," he added under his breath, before noticing the kids "hey kids and…you other two teenagers I don't know."

"Really? We're guests at your so-called hotel," Kim said angrily "I yelled at you earlier when you overcharged my friend for some old necklace."

"Oh yeah," Stan commented "how you doing?"

"Grunkle Stan, are you still on this hotel thing?" Dipper asked "this is going to fall apart, just like your bottled water business."

"Hey, that would've worked if the pool was open longer, and not so well guarded," Stan replied "where the heck were you anyway?"

"Visiting Gideon in prison," Mabel replied.

"Oh yeah? I think maybe I'll do that sometime so I can point & laugh at the little mutant's misfortune," Stan said "anyway, I'm glad you're back; Soos has disappeared, so I need you kids to work overtime to cover his shift."

"No can do Grunkle Stan, we have to find a dangerous mask before a pair of villains do," Dipper told him.

"Come on kids, I need you, I can't run this place by myself!" Stan pleaded as they walked off "kids these days, have no respect for their elders."


Soon the gang gathered in the Shack's parlor to plot their next move.

"Okay, I am sick of waiting around for Drakken & Monkey Fist to make the next move," Kim said "I say it's time we find them and stop them."

"Oh yeah, I'm on board with that idea," Mabel added happily.

"Well, you two know Gravity Falls better than anyone, any idea where they might be?"

"Hmm, two villains like them would probably need a place that's abandoned, where not many people go," Dipper mused.

"The library?" Mabel suggested.

"Unlikely," Dipper replied "also, the place might be connected to Gideon. Maybe that old factory up on the hill?"

"Or his dad's house."

"Yeah right Mabel, no villain would actually hide out in such an obvious location."


But of course, Dipper had no clue how right his sister was, for at that very moment, the villains were putting the final step of their plan into effect.

"I am beginning to lose patience," Monkey Fist said "I assumed with various high tech devices and assorted thugs at your disposal, it would not be difficult for you to locate the key needed to find the Mask of Magorga. Obviously, I thought wrong."

"Don't give me lip, monkey boy," Drakken told him "I spent most of the day having to recover from injuries I nearly sustained in a bar brawl, and I failed to defeat Kim Possible!'

"The cheerleader will be no threat to us, if we locate the key," Monkey Fist explained "for then, the mask will be ours, and she shall be but a pawn for us to control."

"And that may be sooner than you think," Drakken said "thanks to the little bug Shego planted, we shall listen in on their conversation."

"And that helps us, how?"

"Kim Possible almost always thinks one step of ahead of me," Drakken explained "if anyone can find the key, she can."

"Have to admit Dr. D, this is actually a pretty clever plan," Shego said, as she filed her nails in the corner.

"Yes, I am rather proud of it myself," Drakken commented "now, what do you say we listen in, eh?"


"Hey Dipper, maybe there's something in the journal about the amulet?" Mabel suggested.

"I doubt it; I don't recall reading anything about a mask in there."

"Duh, Gideon knew about the mask from his book, remember?" Mabel told him "so if he never found the amulet…"

"Then maybe it was written in a different book," Kim replied, "good thinking Mabel."

"Yup, that's what I do, save the day," Mabel said, putting her arms behind her head.

"Okay, let's see," Dipper said, flipping through the pages "not seeing anything…hang on. 'In my previous book, I documented the power of the dangerous Mask of Magorga'" Dipper read "'in order to keep others from locating the mask, I have separated the information about the amulet needed to locate it; if found, the amulet will lead to one of the mountains and placing it in a special groove will open a secret cave revealing the mask.'"

"Gasp!" Mabel exclaimed.

"Wow, that was incredibly helpful," Dipper commented "there's even an illustration of the amulet, see?" he added, showing the page to everyone.

"Oh no!" Kim commented.

"What?" Ron asked.

"I know where the amulet is."

"You do? How?" Mabel asked.

"Because it's the same one Tara bought from your uncle yesterday," Kim explained.

"Oh man, we had it the whole time and didn't even know it!" Mabel exclaimed "what are the odds?"

"Where is Tara anyway?" Ron asked.

"She went to go hang out with that girl Wendy and her friends," Kim told him "I suppose you two know where to find them?"

"You can count on us!" Mabel said.

"Then let's get going," Kim said "we need to get to Tara before Drakken and company find out the amulet she has is what they're looking for."


"Too late Kim Possible, you've already told us all we need to know," Drakken said, having heard everything through his radio.

"You do know she can't hear us, right?" Shego asked.

"Of course I know that."

"Hurry, time is of the essence," Monkey Fist told him "we must locate this band of teenagers and obtain the key before the young hero and her friends do."

"You leaving already Mr. Fiske?" Bud asked.

"Yes, I've just become aware of a rare archaeological treasure located in the area," Monkey Fist explained "and we're heading off to dig it up."

"I don't see any shovels."

"They're waiting with my crew over by the dig site," Monkey Fist told him.

"Oh of course, that makes perfect sense," Bud replied "well, ya'll have a good dig."

"We shall…you rotund buffoon," Monkey Fist replied under his breath as they headed out.


Back at the Mystery Shack, the twins were preparing themselves to head out to find Tara.

"Hey Dipper, check me out," Mabel said, emerging wearing a plain looking sweater with no designs on it.

"That's a new look for you."

"Yup, I call it my 'mission sweater,' like how Kim has her own mission clothes," Mabel explained "isn't Kim awesome? She has all kinds of fun adventures, and gets to fight crazy villains. And I love how she uses shortened version of words; and to think, all this time, I've been using full words like an idiot!"

"It's nice that you idolize Kim, but I think you might be taking this a little too far," Dipper told her.

"Pfft, no I'm not," Mabel said "I mean, if I copy Kim, does that mean I'll have an action packed life and a boyfriend and stuff? I mean, it prob will happen, but it could not."

"Mabel, you can't just copy someone and expect your life to be just like theirs."

"Duh, sure you can."

Dipper ignored his sister and both walked outside to where Kim was waiting by the Sloth.

"Check it out Kim, I've got mission gear like you!" Mabel said, gesturing to her sweater "and what's this?" she added, digging in her shorts pocket "oh my gosh, it's a grappling hook! Pretty sweet, am I right?"

"Oh yes, it's, certainly something," Kim replied, slightly unnerved "now, hop in the car and let's go."

"How fast does this thing go?" Mabel asked "cause sometimes I get carsick."

"It can go way fast, but we won't need to use top speed," Kim told her "still, buckle up."

Activating the ignition, Kim pulled the purple car out of the Mystery Shack parking lot and drove it towards her destination, hoping she wouldn't be too late.


Next time, Tara meets the gang and makes a connection with Lee, but things soon go sour when the bad guys arrive in search of her necklace.
