Stu Pickles was working on one of his greatest inventions, a ghost portal. He didn't believe in ghosts though. He was paid to make the portal for Vlad Masters.

"Once this portal is complete I will be able to go into the ghost zone again." Vlad had said to himself. He wanted his revenge on Danny Fenton for a long time. Vlad had paid Stu to build the portal since he was a good inventor.

"The portal should be done by tonight or tomorrow morning." Stu said to Vlad.

"Excellent." Vlad said. "I'll be back tonight to see if you're done."

"Don't worry Mr. Masters. I'll do whatever I can to finish it." Vlad smiled at what Stu said and walked off to his limo. The limo drove off from the Pickles house.

Dil and Tommy watched the limo leave as they were coming back from school. "I can't believe that dad is actually making a portal to the ghost realm." Dil said excitedly.

"Dil get real. Ghosts don't exist." Tommy told him.

"Just because that you never saw one doesn't mean they don't exist. I want to go see the portal."

"You think dad will let us? He has only left the machine to sleep and to get something to eat once in a while."

"Let's call our friends over to let them see the portal."

Tommy sighed, "I don't know when you will learn that ghosts do not exist." The boys entered the house and went to their rooms. Dil decided to call the gang to come see the ghost portal.

"You mean that invention downstairs was going to be a portal, Dil?" Phil asked on the phone with Dil.

"You got it man. Are you going to come over?"

"Yeah count us in Dil." Phil said and hung up.

Dil decided to go to the Java Lava since he forgot the number to the place. Dil walked in and saw Kimi working. "Hey Dil, where's Tommy?" She asked him.

"He's doing his homework right now. I was just wondering if you and Chuckie want to see the portal our dad is making today." He asked her politely.

"You mean that invention your dad has been talking non-stop for the past few days? Count us in." Kimi said as Chuckie came through the door.

"Count us in for what?" He asked his sister.

"Oh we're going to see the portal Dil's dad has been working on for the past few weeks."

"That actually doesn't sound like a bad idea. When should we come over?" He asked Dil.

"My dad's showing it off tonight. Come over when your shift is over."

"Will do see you later." Dil walked out the door and went home.

Meanwhile at Amity Park, Danny's parents heard that Vlad was getting a new ghost portal that was made by Stu Pickles. The family packed their bags and went to California. (I do not know the name of the city where the rugrats live.) Danny was getting a little mad at Vlad for hiring someone to build the portal for him. Jazz tried to calm Danny down which actually worked.

"Danny, I know Vlad gets on your nerves but try not to show it in front of mom and dad." Jazz said to Danny.

"Thanks Jazz. I just wish Vlad would stop paying people so that he can have a ghost portal like we do. He does everything he can to kill dad, and you know that now. I just hope nothing happens while we are there at the Pickles house." Danny said.

"Don't worry about it ok. I'm just glad that dad got an invite instead of coming uninvited so we don't get into trouble." Jazz said relieved.

"Hey kids we're here." Their mom said in excitement.

That night all of Tommy's friends were here because of Dil. Tommy wasn't happy because of this. He found out that a family called the Fentons had come over because of being good friends with Vlad in college.

Everyone there was ready to see the portal turn on.

"Everyone put these goggles in so the light won't hurt your eyes." Everyone puts the goggles on. "Here we go." Stu plugs in the portal but nothing happens. "I don't get it. What went wrong?"

"I think you should check it out in the morning Mr. Pickles. You look like that you haven't got enough sleep." Vlad had told him.

"I guess your right." The grown ups and Jazz went upstairs to the living room. Tommy and the gang wanted to figure out what was wrong with the portal. Danny stayed and watched what they were going to do with the portal.

"I thought that the portal into the ghost realm will work." Dil said.

"Dil how many times do I have to tell you that ghosts don't exist?" Tommy said. Danny was just leaning against the wall.

"I wouldn't be sure of that." Danny said to Tommy. The gang stared at him.

"What are you saying?" Chuckie asked.

"I've seen ghosts all the time since my parents built their portal."

"Wow, you actually saw ghosts?" Dil asked him.

"Yes I have."

"I doubt that ghosts exist. I doubt that he has seen any ghosts either." Tommy said. Danny walked over to him.

"I dare you to walk into the portal. Any one can join him if you like." Danny said to everyone. Chuckie backed away. Phil and Lil both shook their heads no. Dil ran into the portal, and Kimi walked into the portal to give Tommy comfort for not being the only one. Tommy gulped and went into the portal. When he was in the machine with Kimi and Dil, Dil accidentally pressed a button. Then out of nowhere the machine turned on. Tommy, Kimi, and Dill were all being shocked inside the portal.

"KIMI!" Chuckie yelled and tried to get in but was stopped by Danny. "Let me go that's my sister in there and she' going to die by that electricity going through her body."

Danny stared at him and said, "Don't worry. She'll come out alive."

What happened next shocked everyone there except Danny. Tommy came walking out first. His hair was now green instead of purple and his eyes were glowing yellow. He had on a green shirt with the symbol T and L together. His pants were now shorts, and the color was red.

Dil came out next. His hair was now white and was smoothed out instead of the usual bushy. His eyes were now glowing blue. He had on a yellow and white shirt with the symbol D and L together. He was wearing shorts that were now yellow on the left and white on the right.

When Kimi came out she had grey hair. Her eyes had started to glow purple. She wore a shirt with the color red all over it with the symbol K and A together. She had a black skirt going to her knees.

"What happened to them?" Phil asked.

"Their molecules got rearranged. Now they are what ghosts call them, halfas." Danny said to them.

"What's a halfa?" Lil asked politely.

"A halfa is a person who has his or her dna mixed together with ectoplasm making them half human and half ghost." Danny said in a calm voice.

"How do they turn back to normal?" Chuckie asked.

"All they have to do is think about being in their human form. They won't have control at transforming at first, but once they get use to it. They will learn how to control their powers."

"How do you know all about this?" Phil asked this time.

""I'm what they call a halfa also." Danny transformed into his ghost form and walked over to the other halfas. "I've been in the ghost zone many times, and I have seen things that some people will probably never see in their life." One of Danny's new powers was to transform other people back to their original state if they were halfas. He tried this for the first time. Phil, Lil, and Chuckie watched as the three halfas went back to their original human form.

"Now I wish that I went into the portal." Phil said to everyone conscious. Tommy was the first one to wake up.

"What happened?" Danny changed them back before Phil said anything. He also changed back to his human form. Tommy saw Dil and Kimi starting to wake up. "Why do they look like that?"

"When you three went into the portal, your body was fused with ectoplasm." Danny stated.

"Your dna had gotten fused together, and you guys have become ghosts." Phil said.

"Awesome, I'm a ghost." Dil said.

"Think about being human." Danny said. The three new halfas obeyed and went back to their original form. Danny smiled.

"Aw man, I thought I was all ghost." Dil stated.

"Actually you can transform from human to ghost and vise versa. You are actually half ghost and half human." Danny said. He started to walk to the stairs. "Unplug the portal and go to bed. I'll tell you more about being half ghost tomorrow." Danny said and left.

"Is it just me or is that guy creepy?" Phil asked.

Tammy answered that while unplugging the portal. "He is very strange to me too. I just hope there is nothing else besides just having a ghost half." When Tommy had said this his foot went intangible and went through the floor as he walked to the stairs. He fell down and hit his head on the floor. "What had happened?"

"Your foot it went intangible or something like that." Dil said while helping him up. The gang went upstairs, and everyone had gone to bed at their house. Kimi had a little trouble while walking home, but Chuckie helped her out.

"He has a little explaining to do with these powers I now have." She said to Chuckie.

"I couldn't agree more Kimi." Chuckie said.
