Chapter 6 – "Mystery Mountain's Mystery."

Previously on "BMO's greatest adventure!" BMO had left Junktown with the two possessions that once belonged to Betty Petrikov, the creator behind the Beep Cheep, the ancient golden yellow computer chip to restore the land of Ooo. While BMO finished listening into Betty's Journal for the night, an annoying two-headed duck stood in his way while he was half-asleep. After defeating the two-headed duck by sending it to the Mainframe Game Frame, he continued researching on Betty the next morning. Not only did more of her life unraveled infront of BMO, he found out who the man in the Locket was, a man by the name of Simon Petrikov, former husband of Betty Petrikov. Also, not only did BMO find more information about what the Beep Cheep is, and where Betty ran off to with it, somewhere deep inside the Mystery Mountains.

BMO was huffing and puffing with every step he took while on the path of the Mystery Mountain. His arms swinging sluggishly, digital sweat drops running down his screen, acting like if he was tired, to which he was. He stopped for a moment, to look up at the bath, which he began to get a little confused. Everything infront of him was starting to turn black and white, but the ground he stood on was still in color. He tilted his body slightly, which he begun to get nervous, but he continued walking. He soon gotten onto the other side, on the black and white side, knowing that he was now on Mystery Mountain, as he began to make his ascent towards the path.

The sound of hard blues music began to play in the background, with the lights and shadows bouncing off things, like the trees, or the rocks, maybe even the animals that were there. He soon arrived to a small town on the top of the mountain, looking around at everyone that was walking by or walking around. He could see cats, mice, chickens, mice, etc. He then walked up to the bulletin board in the center of the town as he began to look over everything that was on it. Seeing lots of things for sale, seeing the local news pinned up from the Globball games, etc. but there was one thing that caught his eye. He reached up and ripped off a poster that gave a description:

"Wanted: Private Detective needed to help solve crime of missing information pertaining to the former scientist Betty Petrikov. Reward offered to anyone who can solve this crime."

BMO's eyes cut sharply as a white line ran onto his cheeks. He reached into his chest panel and dug around, pulling out a dusty wrinkled Detective's hat. He brushed it off and stretched it out, putting it on top of his square head. He grinned slightly as he began to speak into the back of his mind "I thought I would never see this life again. After solving the mystery of the missing sock, I was hit by a Dracula by King Kong, when my sweet sweet Lorraine stole not only the treasure, but Finn's sock, and my circuits, I vowed to never return to this life again. But now, I must do so, if I wish to solve the mystery of the Beep Cheep." He walked away, heading to the Office as the hard blues music began to play more.

He soon walked into a small room, where he seen a person, sitting in a chair with his tail swaying. BMO knocked on the wall slightly as the person looked up. He meowed softly, ears twitched. He sat up as he asked BMO "Nyaaa may I help you?" BMO tipped his detective's hat over, to expose his eyes batting at the person, as he spoke to him "No, but I'm here to help you." He sets the poster down on the table. The person meowed again as he spoke "Nyaa whiskers and catnip toys, you want this job?" BMO said in a bit of a serious tone, but didn't sound too serious with his natural squeaky voice "Do I look like I'm here to play games with you? Yes, I do want this job." The person nodded as he exposed his head from the shadows. It was actually a cat, a full grown cat standing on all fours. He stood infront of BMO and spoke "I am Lieutenant Tabby Hairball, and I run this little detective office. Who should I call you?" BMO grinned as he spoke "Just call me BMO." Tabby nodded as she purrs and licks her fur. The sound of the hard blues music and the sound of her licking herself meld. She soon finished as she sat down and began to explain everything to him.

"You see BMO, a few days ago, I sent another person over there to help investigate. His name is Officer Chase Hisowntail. He was at the book place, where he found a few books missing from the local book place. While there, the criminal left this on the door." He reached onto his desk and pulls out a piece of paper. He then went on "It's a riddle that no one can solve. Maybe you might know, since you're a computer." BMO looked down at the riddle as the riddle said:

"If I have it, I don't share it. If I share it, I don't have it, what am I?"

BMO tilted his head, scratching the side of his panel as the room was silent. The sound of hard blues could be heard in the background as he snapped his fingers. He looked up at Tabby and spoke "A secret. This villain has a secret. Maybe he knows more about Betty than before. We won't know what that secret is unless if I catch him. Do you know what this person look like?" Tabby nodded as she pawed at her desk, reaching in for a picture as she laid it down. BMO picked the picture up and seen the person.

This figure looked similar to BMO, except it was smaller, beige, had only one button, fits only discs, and no control. But it had the CMO letters on its sides, with its arms out of the O, and its legs and arms were darker.

Tabby then spoke to him "That is some person named CMO. He's been stealing information about Betty, and some weird information on that Beep Cheep story. There have been people and sorts coming through here, just to go find it, and no one comes back. But CMO claims that he knows more about the chip, and knows where it is. Please, go stop him, he is up to no good!" Without a second thought, he tipped his hat to Tabby and walked out of the office. BMO then talked to himself, with the blues music playing. "CMO… that no good little computer of mine is back. Last time I heard from him, he was in City of Thieves, stealing from other computers. He has always been a bad program from the "mother" board. I wonder what he wants with the Beep Cheep. Well, it's time to go find out where he is." He would then go walk down the street, before another computer-like screech would go off. BMO then took off to the site, running down the street as fast as he could with his short stubby legs.

BMO ran around the corner, and didn't see anyone there. However, he did see an old J.J model robot standing there. Its screen was cracked, its monitor was bent, and it had scruff marks on it. Surrounded by the J.J model robot was CD's scattered everywhere. There was one CD missing, and the rest of them broke. BMO would then ask "Did you see who done this?" the robot shook his head and spoke "No, but he left me this!" He pulled out a piece of paper that had another printed riddle on it. The riddle said:

"What do you get when you cross a computer with an elephant?"

Everyone that surrounded BMO and the robot talked among themselves, as if some rumor was being passed around. BMO then spoke to the robot "It has lots of memory. This villain is a computer like me, so it is showing off by saying that it has a lot of memory." BMO's cheeks puffed out as he spoke "I am incapable of emotion, but this is making me ticked!" The blues music would play again as BMO walked off into the distance, away from the crowd. He soon spoke to himself "He is being more beeping persistent with all of this information. But CMO seems to be determined to get that Beep Cheep, just like me…" He said as he would then go around the town, showing the picture, and asking if anyone has saw CMO lately.

What seemed like hours, someone had finally told him the most recent sighting of CMO. One of the mice told him that he had seen CMO down by the local paper place. He made a smug remark like "I don't know why a computer needs paper, he doesn't need it." He then walked off. BMO grinned softly as he spoke to himself again, with the blues music playing "Well well well, I guess I can say that this will not compute well for CMO, when I get the jump on him." He chuckled to himself, and arrived at the paper place.

He quietly tip-toed in as he could see so much dust and dirt caked on everything. He would walk down the small hallway as he seen a light gleaming from one of the window doors. BMO looked in the dirty window as he would see CMO. He had his computer screen light shining on the old newspaper articles from 50 years ago. BMO slowly tipped-toes into the room, hiding behind stacks of newspapers as he would stay quiet. CMO would look around, because of his paranoid state of mine. He then fell over as BMO tackled CMO down, rolling around as he had CMO's arms tied behind his back. CMO struggled and spoke "Beep! No one will stop me from the truth!" he headbutted BMO with the back of his head and ran off. BMO rubbed his panel and chased after CMO down the small hallway and out the door.

They both ran down the streets as the exciting fast blues began to play in the background. They both weren't running far, since their short stubby feet made it hard for them. BMO then tackled CMO again, making him fall on his face. BMO raised his hand over CMO and spoke "BMO Chop!" He hit CMO's head and made him unconscious. BMO took out tiny pair of handcuffs as he spoke "You have the right to remain typeless. Anything you say in normal or in binary will be held against you in the court of computers. You have the right to a computer, if you can't process one, one will be processed for you. Do you under your rights as I have beeped them to you?"

CMO groaned and swore in binary code as he spoke "0111101000001010!" BMO laughed and brought him back to Tabby. BMO then took his USB cord and attached it to CMO's head USB. Their minds were linked together as BMO would suck the information he got from CMO. CMO twitched and beeped like a fax machine. Tabby hissed and groaned as BMO was finished. He soon unplugged himself from CMO as BMO spoke to Tabby "I now know what he knows… I know where the Underground City is to the Beep Cheep…" He would take his detective hat off and would set it on the desk, leaving the office. The sad blues harmonica music would play as BMO walked out of the Mystery Mountain city. He soon would play the information he got from CMO while walking passed the black and white barrier, into the color world again.

Mainly all of the information that he had gotten from the newspaper articles was about the Beep Cheep, about all of the example trials shown in the pictures, about how well it did. Then there were articles from Betty, speaking on behalf of the Science groups that developed the Beep Cheep. Also, it shown before and after photos of what the Beep Cheep did into restoring the plants, life, etc. The photos soon shown what kind of equipment was needed into using the Beep Cheep: A computer with a large processor, and a satellite to emit the large waves of information and energy to spread to the four corners of Ooo.

BMO would soon see the Mystery Cave at the top of the mountain, and a few steps in, was a metal, but rusted, latch entrance. He then would open the door as he seen the striped yellow and black ladder going down underground. He gulped softly as he nodded to himself and would begin to descend down underground.

With all of the new information dealing with the Beep Cheep and Betty, what can he expect? Could he expect other rogue computers and robots? Or could he expect something easier for once, that could help lead him to the Beep Cheep. Would all of this end soon, or would all of this finally get to him and short circuit him?
