Well, here's chapter 2. I'm trying to get in as many chapters as possible before writer's block comes around, like it did with my other story.

By the way, this whole story takes place within a several-month timeline, to get the plot developing. By the way, in this story, Retroville High has about 400 students. Sorry about not putting Goddard in it yet, but he'll make an appearance in the next chapter.

"We've got to shut it off!" Carl said in a panic.

"No, if we do that, he could be trapped there!" said Jimmy. "Will, what were the coordinates?"

"44678-9663." he replied. "I don't know where it is, but since it was in your handwriting, I thought that was going to be where we would explore."

"Carl must have grabbed it and thought the same thing you did." Jimmy reasoned.

"How do we get him out of there?" exclaimed Carl.

"Maybe if I can get a tractor beam inside the portal, we'll be able to bring him back."

However, just as he said those words, Sheen was launched right into Will's arms, who set him down gently. He now looked completely different. Instead of his blue shirt and black pants, they were green and white. His eyes were now a light Orange.

"What in the 4 hells happened to him?" asked Will.

"It looks like his DNA had been affected." said Jimmy. "I'll need to take a blood sample."

He took out a syringe and sucked about 50 grams of blood out. He put it under his computer's scanner.

"Vox, analyze DNA." said Jimmy.

The results showed some long streaks of DNA among the short ones. Also, the long ones were somewhat Green in color.

"It looks a lot like ectoplasm, except that the green is lighter than what I've seen." said Will. "I think we better look at his blood. Vox, magnify blood by 3000x."

The computer complied and they saw ectoplasm everywhere in the blood and beginning to merge with the normal cells. All present were in a panic by this point.

"It seems to be trying to control the cells." said Jimmy. "I saw the same thing with the DNA."

"We don't have anything to stop the merging." said Will. "I never brought back a Hornaka's blood, and by the time I went to their native planet and back, it'd be too late. Still, there's something I was told about it, but I can't quite put my finger on it."

"Let's see where the coordinates lead to."

"What do I do while you guys look at it?" asked Carl.

"Just don't do anything else to screw this up." said Will.

They were finding out just what world it was, and it turned out to be the ghost-zone.

"That can't be true." said Jimmy. "Ghosts don't exist."

"Not in this world, but we've got to go somewhere when we die, and this is probably it." said Will.

"We better cut the power now!"

"It doesn't seem to be working. Until we can shut it down, anything can come through. We better find some anti-ghost weapons, but where can we?"

"The ghost hunter Jack Fenton is Daniel's father. We better see him as soon as possible to get an idea for equipment. They'll probably be made out of ectoplasm."

"I can get that if you give me a few days."

"I don't think we have any time. We have to do something now!"

"Guys, Sheen's waking up." said Carl timidly.

"Whoa, what happened?" asked Sheen.

"Well, for starters, you're floating about a foot off the ground." said Jimmy. "I think you're now part ghost."

"Cool!" replied Sheen. "I wonder what my powers are."

"I wouldn't try experimenting right now. This could be very harmful, so don't do anything until we have more information."

"For now, just try to change back." said Will.

Sheen tried and tried, but after a few minutes, he just gave up. Will put a hand on his shoulder, but as soon as he did that, Sheen became intangible and was falling through the floor. Desperately, he tried to fly and actually did it, but he soon came crashing down.

2 green rings surrounded him and he changed back to his human self. All of them looked worried.

"How do we explain this?" asked Will.

"We better not say anything." replied Jimmy. "There have been reports of ghosts, and I now believe them. Everybody's afraid of them, so if we say that he's half ghost, he's going to have a pretty miserable time."

"He probably doesn't have much control of his powers." said Will. "How are we going to keep it secret?"

His worries came to pass. Over the next 2 weeks, parts of him went intangible for a few seconds before going back to normal. Cindy was definitely noticing something, but she didn't have a clue what it was.

Jimmy couldn't do too much because he was busy trying to stay away from Dash, who seemed to make him his main target. Danny sometimes intervened and defended him, but it wasn't very often.

"What happened to you?" asked Libby during one lunch period.

"Why in the hell would you care?" Jimmy growled, in a very bad mood.

"Neutron, you're getting bullied again." said Cindy. "Why won't you just tell someone?"

Jimmy walked away without giving her a response. He had too much on his mind to really care about either of them.

Over time, Sheen got some control over his powers. Still, it was very embarrassing when his pants fell down while he was flirting with Libby. She had not spoken to him since.

Jimmy took his hover car, and followed Danny home. After waiting a few minutes, he knocked on the door with Carl and Sheen standing beside him.

"Who are you?" asked Jack Fenton. He was a huge man wearing an orange jumpsuit.

"I'm Jimmy Neutron and these are my friends, Carl and Sheen." replied Jimmy. "I'd like to learn about some of your ghost weapons, since a ghost portal has opened up in my lab and we can't shut it off. We need some sort of defense."

"Don't worry, I'll tell you everything." Jack said, hopping up and down like a schoolgirl.

"Are you boring them with your ghost lectures?" groaned a girl. She looked a lot like Danny, only a little older. She saw them and recognized Jimmy. "So you're the one Cindy always complains about. You don't look that bad to me. My name's Jasmine, but call me Jazz."

"Pleased to meet you." said Jimmy. "These are my friends: Carl and Sheen. How do you know Cindy?"

"We've been pen pals for about 6 months. She really trusts me, and I give her whatever advice I can."

Jimmy smiled and followed Jack and Maddie. They lectured on their various inventions and what they knew about ghosts. He was listening attentively.

"Can I borrow some of your inventions?" asked Jimmy. "At least until I build my own."

"Of course you can, Jim." replied Jack. "I've got hundreds of them. Besides, with Dannny…"

"Jack…" Maddie said, giving him a warning look.

"Right, sorry. Anyway, they'll be ghosts coming out of your portal and you need to know how to fight them. Here's a copy of the Fenton Thermos, Fenton ghost fisher, Fenton ghost gloves, and a couple of ectoplasmic weapons. That ought the give the ghosts a challenge."

"Jack, it's time for our ghost patrol." said Maddie.

"Yes, it is. Well, just make sure any ghost that comes out of that portal is sent back. We can't have them run around."

Meanwhile, Carl was following Jazz, rapidly developing a crush on her, while Sheen was trying to hold her back.

"Carl, quite developing useless crushes!" said Sheen. "All she's going to do is reject you."

"But she's beautiful and kind." replied Carl. "I wonder if she likes Llamas."

"I doubt it, and who cares? You're going to scare the living daylights out of her if you don't stop!"

"Ghost directly ahead." said a mechanical voice. Jack showed up and the machine immediately identified Sheen. Jack took out his anti-ghost weapons, leaving Sheen to run for his life.

Carl was trying to follow Jazz, but he lost her.

"What are you doing up here?" asked Danny. "You're another one of the guys with a crush on my sister, aren't you?"

"I can't help it!" yelled Carl.

"Just be quiet and don't say anything about it. She's busy writing on her computer, and she'll be furious if you disturb her. Just go rejoin your friends."

Jimmy was analyzing the machines and reporting back to Will.

"Based on your information, I can get started right away." said Will. "Still, I'd like to see the actual copy before trying to build one. I still remember your earlier inventions. William out."

He saw Sheen running from Jack and his ghost inventions. Maddie stopped him and wanted to hear the story.

"So either the Ghost Finder isn't working, or we've found ourselves a Halfa!" said Jack.

"Half ghost, half human, right?" said Jimmy. "I guess I can tell you, but don't tell anyone else. He's had these powers for nearly a month, and Will and I don't have a clue what to do about it."

"He'll get control in time." said Maddie. "It'll take about 5 months for his body parts to completely stop fazing at random, and his ghost abilities should show in about another 2 months. If what you told us is true, he can now morph from ghost to human at will, but only for a short period of time."

"You'd better train him in fight." said Jack. "There's going to be lots of ghosts around soon."

"I'll try, but he's really hyperactive." said Jimmy. "He doesn't really know how to fight, but I think I can teach him."

Suddenly, a ghost fazed into the room. Sheen was about to go ghost when Jack stopped him. He was skinny and was mainly black with a few white spots, including his hair.

"Don't worry, it's Phantom." said Jack. "he's on our side and also a Halfa, so nothing to worry about. Any ghosts around?"

"I'm not sure, but I think I saw a few ghosts flying out from the East." replied Phantom. "I'll capture them as soon as possible."

"Hey, let me do it!" said Sheen. "None will get past me!"

"You better train a little first before you go out fighting." said Phantom. "You may be half-ghost, but you can be killed, don't forget that. Also, you better train before fighting."

"After he's trained, Me, Goddard, Sheen, Carl, and William will be able to beat any ghost!" said Jimmy.

"I wouldn't be so sure." said Jack. "Some are difficult to beat, and there are a few exceptionally dangerous ghosts."

"Even I have a very hard time beating them." said Phantom. "The most deadly kind are probably shape-shifters. They can even look like a human."

"We better watch out for them, then." said Jimmy. "I think we better go now. Thanks for the info!"

They all went back to the lab and gave Will the weapons the Fentons gave them.

"From what you've told me, I have an idea who the other halfa is, but I want more evidence." said Will.

"Never mind about that now." said Jimmy. "Let's begin building the ghost weapons."

Well, that's the second chapter. Don't worry, there's going to be some action in the next one, sort of Sheen's first test in real fighting.

There will be some romance in the story, but not till towards the end. I'm trying to keep them as in character as possible, but I'm sorry if I made any mistakes.
