The black SUV takes them to a large mansion a few miles outside the Tri-City area. It stops just short of the high, intimidating gates before they slowly open. The SUV lurches forward, driving up the long driveway before stopping in front of the mansion's elegant wooden doors. A middle aged, medium height man wearing a green polo shirt, khaki slacks, and white deck shoes greets Kim and Ron as they climb out of the SUV.

"Kim Possible, I'm so honored to meet you." The man turns to Ron "And you would be…"

"Ron Stoppable. I play a more supportive boyfriend, sidekick distraction role."

"Okay," responds the man. He offers his hand to Kim and then to Ron. "Anyway, I'm Stewart Emerald."

"Nice to meet you, Mr. Emerald," Kim cordially responds and shakes his hand. "So let's get started. Where was the mask before it was stolen?"

"Right to the point. I like that. Follow me and I'll show you."

Emerald takes the teens inside his mansion. They pass several priceless paintings, vases, and furniture on there way to his library. On the floor, Kim notices a trail of black ash leading to the library from the grand stair case and from the stair case to somewhere in the upper floor. She bends down on one knee to have a closer look.

"The burglar entered my home through my hearth in my private study upstairs," Mr. Emerald explains. "He left a trail of ash footprints all over my new oriental rug, which just burns my toast almost as much as the theft of one of my masks."

A realization quickly hits Kim. "They would be more intact in the study," she says. "I'll quickly go up there and scan one with the kimmunicator so Wade can analyze it. Be right back." Kim follows the trail back to the study leaving Ron and Mr. Emerald standing outside his library. Rufus comes out of Ron's pocket and climbs up to Ron's shoulder.

"Hi," a greeting Rufus exclaims to Mr. Emerald.

"What is that, a hairless, bucktooth rat?"

The description offends Rufus who angrily exclaims, "Hey!"

"Rufus is a naked mole rat, thank you very much," Ron responds defensively.

Up in the study, Kim finds a relatively intact footprint near the hearth of the chimney. By now, Wade joins her via the kimmunicator and waits for the scan. "Just aim the kimmunicator at the footprint and I'll be able to analyze it," instructs Wade.

Kim begins to aim the kimmunicator at the footprint when something about it seems odd to her. "These are bare," she exclaims.

"What?"

"The burglar wore no shoes. In fact these look like the footprints of a large monkey."

Kim and Wade simultaneously exclaim in unison, "Monkey Fist!"

"You know what this means," Wade says.

"That the mask comes with some monkey theme attach to it. I better tell Ron."

"Kim, wait. You better still scan the footprint. It might give us a clue of where Monkey Fist has been."

Kim aims the kimmunicator at the footprint and a red beam shoots out of itengulfing the footprint. A digital image of the footprint appears onits little screen.

"I'll analyze this and get back to you," Wade says.

"Thanks Wade."

Wade signs off and Kim stuffs her kimmunicator back into her pocket. She then heads back to the library to meet back up with Ron and Mr. Emerald and to see if Mr. Emerald can shed some light as to the reason why Monkey Fist would want his mask. She begins to suspect that it may have some connection to the mystical monkey power possessed by Monkey Fist and Ron, which worries her.

"No way!" Ron almost shouts.

While waiting for Kim to finish finding and scanning a viable footprint of the burglar, Mr. Emerald escorts Ron and Rufus, still standing on Ron's shoulder, into the library to view the damaged display case that once held the now stolen mask. Looking over the rest of Mr. Emerald's remaining collection, a beat up hockey mask with a large scratch thatgoes from the forehead, passing through the left eye hole, and down to its chin catches his attention.

Mr. Emerald responds, "Yes way!"

"Is that the mask from the Slasher movies?"

"That particular mask is from Slasher V: Reborn and Enraged. My makeup was used for the gruesome face of the slasher and for the victim's dead bodies."

"Cool."

Rufus stares at the mask when he notices the punched opening in the display case and sees a small wad of black hair attached to one of the opening's jagged edges. He begins to alert Ron to the piece of valuable evidence he has just found by squeaking and pointing at the opening. Ron, still mesmerized by the Slasher's mask, unintentionally ignores Rufus's promptings.

Rufus however draws the attention of Mr. Emerald. "Ah, son, I think your mole rat is trying to tell you something."

"What?"

Ron turns to an exuberant Rufus on his shoulder and follows Rufus' pointings to the jagged opening of the display case. He seesa wad of black hair and leans in for a closer look, which allows Rufus to sniff it. Immediately, a disgusted look forms on Rufus' face, "Monkey!"

A cold expression forms on Ron's face as he realizes this could only mean one thing, "Monkey Fist!"

Mr. Emerald asks, "Who?"

"My arch foe," answers Ron as his cold steely expression remains.

"Since when do sidekicks have arch foes?"

Before Ron can respond to Mr. Emerald's question, Kim bursts into the library with an excited look on her face.

"Kim, it was…"

"Monkey Fist!"

"How did you…"

"Footprint next to the hearth in the study. You?"

"Wad of hair caught on the jagged edge of broken glass in the library."

"All right we established who the thief is. Now we need to know why he would want this particular mask."

"Obviously it has to do with becoming the monkey king or something along those lines and ruling the world," Ron shakes his head, "so predictable."

"Do you know anything about your mask that might be useful, Mr. Emerald?" asks Kim.

Mr. Emerald answers, "Well, when I bought it from a vender in China, he said that in the wrong hands it could be very dangerous. Then he said he only takes cash and not personal checks. That was it. I didn't press for details because I thought the old man was just trying to spice up my interest with some superstitious garbage so that I would buy it."

"Why did you buy it?" asks Ron.

"It was one of the most bizarre things I had ever seen. It gave off this eerie, creepy vibe and I knew I just had to have it for my collection."

"Can you describe it?" Kim asks.

"It's called the Mask of Guaduelme and I can do one better. I'll show you. I keep a photo of all my masks in my wallet."

Mr. Emerald reaches into his back pocket and pulls out a large wallet due mostly from keeping a wallet sized photo of every mask he owns and not from keeping a large wad of bills in it.

"You carry photos of your masks with you," a perplexed Ron exclaims.

"People carry around photos of their loves ones. I consider these masks my babies. Now let's see."

Mr. Emerald flips through the many plastic card holders in the wallet until he finds the desired photo. He shows it to Kim and Ron. "What did I tell you? Isn't it the most bizarre mask you every laid your eyes on."

Kim and Ron stare at photo of a wooden mask decorated to resemble an angry monkey. Red gemlike stones fill its eye holes while its painted devilish mouth grins wickly back at them through the photo. Ron and Rufus' hearts begin to beat faster as they stare into the object of their resent, disturbing dream earlier in the park. Images of the mask hovering over its box flash in their minds while their crawling skin tries to get away from the image before their brains can command their legs to run.

Panic and fear will soon erupt in a most spectacular scene.

"Its…"

Before Kim can finish her sentence, Ron panics and screams, "Evil monkey mask! Ahhhhhhhhhhh!"

Rufus joins in. "Ahhhhhhhhh!"

Ron quickly runs, as if on fire, out of the library screaming while Rufus, also screaming, hangs on for dear life to Ron's shirt.Ron heads to the sturdy decorated front doors but, because of his overwhelming fear and panic, does not attempt to open them. He runs full steam into the closed doors, which do not give. His screaming abruptly stops as he momentarily adheres to the front doors before slowly falling backward and landing on the floor. Rufus lies beside him and both lose consciousness.

Kim rushes over to check on them. "Ron!"

She kneels along side him and cradles his head onto her lap. She gently touches the large bruise on his forehead then delicately picks up Rufus with both hands and checks on him. Mr. Emerald approaches.

"Now that was a 9.7 on the freak scale," Mr. Emerald states as he surveys the scene before him. "Here, let's bring them to the living room. There's a couch we can place him in until he wakes up."

And with that Mr. Emerald picks up Ron and carries him to the living room. Kim, carrying Rufus, follows close behind with an extremely worried expression on her face.
