A/N: I can't help it, but the title of this episode reminds me of something disgusting.

Muddy Bottom!

"So are you guys psyched?" asked Yumi loudly after finding out that her parents were going to be gone for the weekend.

"You bet," said Odd. "This will be the best party ever! I got the DJ covered."

"I hope you aren't planning on using Sissi's music, Odd," said the stern one. "I bet her Jigglypuff can sing better than some of the artists on her CD."

Odd gagged. "Thinking about her taste makes me taste my breakfast again." Later that day, Yumi was getting nervous about asking her parents for permission for the bash. She twirled noodles with her chopsticks while her parents stared.

"…So…," she dragged, "I was thinking about having a little get-together with my friends this weekend while you guys are gone; if that's okay?"

"Hm?" mumbled Yumi's mother. "What do you think, Takeo?"

"I think it's perfectly fine," he said, slurping his soup. "It's just a couple of friends, right Yumi…"

"Oh, thank you!" cried Yumi. She got up and gave her father a kiss on the cheek. "You guys are the best parents ever!" She darted like a Dodrio to her room. Yumi's mother wondered if Yumi was ever going to finish her udon.

"Suck up," uttered Yumi's little brother, Hiroki. Yumi fell on her bed, planning in her mind the things she were going to hold at her party. Just then her cell phone rang. It was Odd.

"Odd?" spoke Yumi.

"Hey, we're having another game of Slip an' Sock!"

"Wanna give me the play-by-play?" Yumi chuckled.

"Sure," said Odd. Yumi heard some muttering in the background. "Oh and Jeremy says that he can't contact Lyoko for some reason."

"Hope XANA doesn't attack us."

Odd gave the details to Yumi as Ulrich slid down the polished hallway on his socks.

"And…it's a new record! 12 feet and 7 inches!" Ulrich jumped jubilantly but stopped when he saw the gym teacher around the corner.

"Uh oh," said Odd to Yumi. "Gotta go. Code: BIG FAT CLOWN." He put on a fake smile as he hung up. "Jim! What brings you to these parts of the hallways?"

"I don't understand you three," Jim grunted with his arms on his waist. "Every vacation you guys always stay behind. Probably because your parents are sick of you. I sympathize with them." Weirded out, Jim left Odd to attempt to beat Ulrich's record. He pulled off his yellow shoes and stood back.

"Jeremy," called Ulrich, "wanna ref?"

"Go ahead, Ulrich," Jeremy responded, typing away on his laptop.

"And…" Odd took his stance, "slide!" Odd yelled as he accelerate much too quickly and fell on top of himself. "Here," Ulrich walked over to him and held out his hand. "Need a hand?" He pulled him up and noticed a white square of paper underneath Odd's foot. "Hey, what's this?" Ulrich wondered as he picked it up. Odd started to sweat.

Jeremy closed his computer and got up. "Who's that girl?" It was a small portrait of a black girl with shoulder-length, highlighted hair.

"Uhh," Odd stuttered, "I've got to get to bed." He grabbed the photo and ran to his room. Ulrich gave a confused look to Jeremy.

On sat on the steps to the cafeteria, thinking about what happened last night. His cell phone rang and interrupted his thoughts. Odd looked at the caller ID then put his cell back into his purple pocket.

"Come on, Kiwi," he called. The Granbull got up from its resting position and followed its trainer to the school gate. He spotted the girl he was looking for. She had on a plaid mini-skirt and was dressed in all black. Next to her was a rugged-looking Sneasel, leaning against the wall.

"Hey, Sam."

The girl turned around. "Hi," she said with a small smile. Odd walked up to her and paused for a second. Then, he gave her a quick kiss on the lips. Granbull walked over to Sneasel.

"Gran?" Sneasel got up off the wall and walked over to its owner.

"So…how's it going?"

"Okay," she responded. "It was hard to get out of school, though." She put on a frustrated look. "Are we here to talk or are we here to DJ?" Odd stopped looking at the ground. "You know what I want, and you know that I want it now," she whispered although there was no one around.

"Alright, follow me," said Odd. He led the two of them to the computer lab.

"Is this it?" she asked, picking up the compact, metallic device.

"It's the most powerful laptop our school has."

"I bet I could mix some cool jams with this. Let's go." She started to take off, but Odd stopped her.

"Wait, don't tell me you're going to steal it."

"How else am I going to prepare for that party?" She motioned to her Sneasel, and it hopped onto her shoulder. Odd was about to answer, but he heard a door open.

"Hide!" He grabbed the laptop and shoved the girl and her Pokemon under a desk.

"Well, well, well," smirked Jim, "if it isn't Odd 'Sticky Fingers' Della Robbia."

"Uhh," said Odd nervously. He realized the cold, heavy object he held in his hands. "A mouthful to say, huh Jim?"

"Uh-uh," barked Jim. "I'm taking you straight to the principal's office."

"No! Wait!" he set the laptop down on the desk.

"The waiting time from this point is 0 minutes, Odd," said Jim, pulling Odd and Kiwi out of the room. Odd's eyes went to Sam's as he got locked out of the computer lab. As Jim was busy with his keys, Kiwi bared is teeth at Jim's leg. Odd shook his head, and Kiwi sat down. Ulrich and Jeremy spotted the innocent purple thieves as the teacher led them to the headmaster's office.

"Odd?" said Jeremy. "Jim? What did Odd do?"

"Ahh," Jim stopped. "I caught this crook red-handed trying to steal a laptop from the computer lab."

"Oh, that's because… " Jeremy tried to make up an excuse to back up his friend.

"…because he needed it for working on a school project," finished Ulrich.

"But if he needed a computer, couldn't he borrow yours, Jeremy?" Jim said. Jeremy protested but Jim responded, "I'm sure your computers are just as good as the best ones in this school. Now…off you go." Jim resumed his duty as he left the four of them in the administration entrance.

When the big, fat clown left, Ulrich started, "What was that all about?"

"I had…stuff," replied Odd. He looked at the front door, where he saw a small, blue Pokemon. "Hey, a Quagsire.'

"Quagsire," its eyes weren't charming dots as normal.

"Uh oh," said Ulrich. The Pokemon raised its floppy arms and launched a Muddy Water attack from its small mouth at the boys. Gallons of gallons of river water flooded the room. Ulrich pulled out the Pokeball from his pocket.

"Go, Nuzleaf!" The Wily Pokemon landed on a sofa. "Nature Power!" The Pokemon fired dozens of bright stars at Quagsire, sending it flying out the door.

"Go, Beldum," called Jeremy, releasing it. "Beldum, has a tower been activated?" Beldum adjusted its eye. If it had hair on its neck, it would have been standing on end.

"Bel," it said in its robotic voice. It circled around Jeremy.

"Let's go." Jeremy led his friends in the direction of the basement.

"Wait." Odd stopped. "I stole the laptop because Sam needed it."

"Sam?" questioned Ulrich.

"Yeah," explained Odd, "the girl. She's locked with her Sneasel in the computer lab."

"Alright, you'd better go, Jeremy," said Ulrich. Jeremy nodded and went down the passageway with his laptop. "I'll call Yumi." Somewhere miles away, John Swamp was giving a news report.

"Good afternoon. Swamp here, at our local river. Reports have come in of knots of Quagsire attacking innocent citizens. As you can see, many Quagsire have left their bog homes and are on a rampage…"

As Odd and Ulrich reached the science building, they were stopped by a wall of Quagsire.

Odd looked shocked. "We have to get through that door." Without warning, a Quagsire used Dig, followed by another one, and another one. "Where did they all go?"

"I don't know, but I don't want to stay here to find out," said Ulrich. "Let's go." He motioned Odd to follow him through the door of the science wing.

"Kiwi! Use Headbutt!" commanded Odd.

"Gran!" The door rocketed off of its hinges, and Ulrich rescued Sam and Sneasel.

"Thanks man," was the first thing she said.

"No time for chitter-chatter," said Odd. "We have to get out of here."

Sam started to look uneasy. "What's going on?" Suddenly, Ulrich and Nuzleaf were thrown onto the wall.

"That's a good question," said Odd as he started to sink.

"Back to the door!" yelled Ulrich. He led the group to the doorway, which was a few feet underground. He climbed up the muddy barrier, allowing him to aid his friends back up to solid ground.

"The school's sinking," announced Odd. "If we don't act quick, we'll be starting to have to wear mining helmets to school!" He and Ulrich dashed in the direction of the woods. Sam and her Pokemon followed, not sure of what was going on.

Meanwhile, Jim was in his office, working on his lats. Loud rock music streamed through his tiny room as he descended to his doom.

"Where's Yumi?" demanded Odd.

"Already on Lyoko," said Jeremy.

"Pick up the pace," said Odd. "I think the Quagsire are coming from the river. They know where the factory is."

"Would someone tell me what's going on?" Sam walked closer to Jeremy.

"Not really," he said as Odd and Ulrich descended down the elevator. "It's a long story."

Yumi and Misdreavus emerged from a scanner, exhausted.

"Yumi, are you okay?" said Ulrich, running over to her help her up.

"Those Hornjasks," she panted. "Misdreavus and I couldn't take on three of them."

"Well four is bigger than three," said Odd. "I think."

"Hey, I'm the Einstein," interrupted Jeremy. "So let me transfer you guys. Transfer Ulrich. Scanner Granbull. Virtualization." Three Hornjasks were taking on Aelita, who had used Secret Power to shield herself by forming a rock igloo.

"Nuzleaf." A Hornjask had fired a Signal Beam at Nuzleaf without warning.

"Wow, XANA's monsters are getting tougher," said Ulrich, taking out his saber. "Better use Double Team." Two clones self-emerged.

"Kiwi, I don't think you can attack these fellas," said Odd. "They're too fast." Granbull nodded and used Scary Face on the leader Hornjask.

"Here I go," hollered Odd. "Laser Arrow!" He launched himself off the mountain and fired three rounds at the leader Hornjask. It was still too fast for him. The other two had broken through Aelita's barrier. Luckily, Ulrich and his doubles were there to defend her.

"Looks like you're outnumbered, XANA," said an Ulrich. The other Ulrichs chuckled as they easily evaded each of the monsters' attacks.

"Ulrich!" warned Jeremy. "The leader's coming back."

"Huh?" Two Ulrichs were now missing. "Aelita! Run!" The leader Hornjask zoomed towards the girl, but out of nowhere, Nuzleaf jumped up and struck it with a Pound attack. It was not very effective… "Try Nature Power," yelled the last Ulrich. Tons of boulders materialized out of nowhere on the three flying monsters. Nuzleaf carried Aelita in the direction of the tower, while two of the Hornjasks were destroyed. The leader was the last one standing.

"I got this one," said Odd, loading his wrist. "Laser…Arrow." The spinning arrowhead punctured the pupil of the monster's eye, causing a huge explosion. Aelita made it across the moving platforms to the tower.

Back at school, Jim had realized the sky was no longer visible, and he was currently in a closet. "Hello. Listen, I need help. I'm at the junior high school, I'm trapped in a closet, and there's tons of mud pouring in here." Jim screamed into his cell phone, "No, lady. This is not a practical joke! Help! I don't wanna die!" Luckily, Aelita entered the code before the mud reached Jim's big head.

"Return to the past, now." The ominous white light spread across the restless city.

"Hey, Sam," greeted Odd.

She turned around. "Hi."

"Listen," said Odd, "if you really want a good computer, I know a guy that has one right now."

"Really?" she said hesitantly.

"Yeah," Odd responded. "He's a real Einstein."

"Alright, Odd. If you say so. Come on, Sneasel," she called to her Pokemon. It was holding a crescent-shaped bone that it found in a bush.
