New story just in time for Halloween.

Lisa Loud was putting the finishing touches on her new device. She was busy torching some of the remaining metal pieces together, with her head covered with a mask. As this was going on, Lily was watching the whole thing with her mask.

"Walla, my device is complete!" Lisa said, uncovering her mask, as she looked at her finished product: a portal opener. Lily uncovered her mask, and gave a laugh at it.

As Lisa was doing this, the rest of her crazy family, the 9 sisters and one son, were busy causing chaos in the living room. Suddenly, Lincoln burst through the locked closed door of Lisa's room, and by burst I mean, what Lori would normally say, LITERALLY BREAKING through the door like a battering ram. He ended up landing on his back in the wall.

"Oh, that is the last time I ever let Lynn use me for throwing practice!" Lincoln said, brushing himself off.

"Ah, Lincoln. I see that you've crashed at the precise time to observe my new invention." Lisa said, dragging Lincoln to where the device was.

"Looks like some kind of portal." Lincoln said.

"And that you'd be correct." Lisa responded.

"Just like the one Jimmy back in Retroville has."

"Actually, I was aiming towards a comparison with Jack Fenton's." Lisa said.

"Jack Fenton?" It took a few seconds for Lincoln to finally put together what Lisa was implying. "Wait, this wouldn't have anything to do with the Ghost Zone, wouldn't it?" Lincoln asked.

"Indeed it would, for after finding the proper titanium, locating the exact stats for this alternate universe and finding some uh…spare parts…" Lisa was too cowardly to admit the fact that she found extra pieces from Fenton products. "I've successfully constructed my own portal to the Ghost Sphere."

"You mean Ghost Zone."

"Ghost Sphere resembles a more scientific name." Lisa said, as she was currently using the control panel on the side of it.

"Hold it, why are you doing this, Lisa?" Lincoln asked. "I thought you didn't believe in ghosts, or at least you didn't want to, after that Syndicate tried to take over the world."

"Well, putting your exposition aside, I decided to brush off the skepticism in my cerebrum, and analyze this pseudo-science myself." Lisa said, as she pulled up a chart from the roof. "Besides, I have a theory that may suggest that these ghosts aren't actually apparitions, but rather extra-terrestrials with ghost-like DNA."

"And here we go again." Lincoln said, laughing this off. "Why won't you ever admit you're wrong about ghosts?"

"Because Lincoln, they disregard and contradict about 342 laws of science. I'm determined to debunk those Fentons on ghosts!" Lisa said.

"What's this about ghosts?" Lucy asked, scaring the two.

"Lucy, how'd you get in here?!" Lincoln asked.

"The door was broken." Lucy responded. "And those ghosts aren't aliens. They're as real as vampires and the souls inside my mirror."

Both Lisa and Lincoln were shocked by this statement. "Argument. Invalid." Lisa smirked. "Now, I must activate this slang named after an infant." Lisa began using the control panel again. But after thinking back to what happened with the Evil Syndicate, Lincoln began to feel uncomfortable.

"Hold it, Lisa." Lincoln said. "I don't think this is a good idea."

"Indeed, older brother." Lucy said. "The spirit world is dark and complex, or to put it into worlds of your favorite rappers…it ain't nothin' to mess with."

"I adore the citation, but a scientist has to discover, what a scientist has to discover." Lisa said.

"But remember the last time we dealt with ghosts?!" Lincoln asked. "We should just leave this to Danny and his family!"

At that moment, the portal finally lit up, with a spinning green light in the middle.

"I did it! I must be the youngest to build a gateway to the Ghost Zone!" Lisa said.

"At least none of us got superpowers." Lincoln said, then sighed at this response, thinking it'd be cool to have Danny's powers.

"Now, I must capture one of these creatures, and study it's DNA, and finally determine that…something escaped out of the portal didn't it?" Indeed, a ghost entered through the portal. It was a black spirit with red eyes, as it gave a laugh.

"Spectra!" Lincoln said. "We meet again!"

"Hello, little Loud child. Good to see your precious face again." Spectra said, holding his cheeks.

"Well, I'm not happy to see the ghost who made my family hate me again!" Lincoln said.

"And now you're going to be ever more unhappy, for I will have my revenge!" Spectra said, as her assistant Bertram, who was a green blob, popped out of the portal and messed with the controls.

"Don't do that! It'll cause an interference with reality and the Ghost Sphere!" Lisa said.

"That's the point, you geeky kid!" Bertram said. "Also, it's Ghost Zone!"

"I don't refer it by that name!" Lisa said. Soon the sphere started to shake. The portal started to leak out portions of the Ghost Zone, like the equivalent of a freezing.

"We better get out of here!" Lincoln said, as Spectra laughed. The three siblings, with Lily ran out, not before Lily grabbed her blanket. The entire house was turning green, as the entire inside was getting sucked inside the Ghost Zone. The three ran downstairs, where all of the sisters were making noise.

"Get out of the house!" Lucy screamed, or at least in her own terms, as she still had her low voice.

"I bet this has Lisa literally smelled all over it." Lori said. However, the sisters ended up getting caught inside the green spell, as they started floating inside the Ghost Zone, while screaming.

"Lisa, what on Earth have you done?!" Lynn Sr., the father said, as him and Rita were sucked into the GZ.

"No!" Lincoln said, grabbing his hand. Lisa pulled Lincoln out of the house, as the three sisters and the brother ended up getting out.

"Sup Lincoln?" Clyde said, happily walking towards Lincoln, but his smile faded as he saw the house fly from the ground, with green lights coming through every window.

"LOUDS!" Mr. Grosse, their neighbor yelled. "Turn off that blasted light show of….OH!" Soon, the house vanished as if it was sucked into a portal. "Blasted magic tricks! You better come back to give me your lasagna!" Mr. Grosse closed the window.

"The house! THE HOUSE! She took the house!" Lincoln said. "Way to go, Lisa!"

"What was that all about?!" Clyde asked, scared.

"My gateway device might've made an error." Lisa said.

"Now we have to find our family!" Lincoln said. "But where could they be?"

"Where else? The Ghost Zone." Lucy said.

"You're right, Lucy. Then this means, ladies and gentlemen, we have to return to the Ghost Zone!" Lincoln said.

"Sweet, I've always wanted to see that place!" Clyde said. "But wait, where else are we going to find a ghost portal?"

"Oh, I know a guy!" Lincoln smiled.

….

Lincoln knocked on the Fenton door, as Danny answered it.

"Lincoln? What are you doing here?" Danny asked.

"We uh…kinda have a problem." Lincoln said.

"Hello, hott...I mean Danny." Lucy said, blushing.

Danny immediately got the idea, after wondering why he came to the door. He looked to Lisa.

"You wouldn't have anything to do with this, would you?" Danny asked Lisa.

"Um, that is…classified information!" Lisa responded.

"Oh boy, this is going to be fun." Danny sarcastically said.

TO BE CONTINUED...

But yeah, this was the opener of the story. This isn't as short as the other short stories, but it's not as long as the main NH series. It's rather the length of an episode.

Yeah, Zim and Dani will also play parts in the story.
