Hey guys!
I know, I've got all my other fanfics to attend to, but I couldn't resist writing this! Recently, I finished binge-watching one of my favourite cartoons as a kid that I rediscovered called Grossology, and I thought, why not make a crossover between Grossology and Danny Phantom? Considering that there's no Danny Phantom and Grossology crossovers on this site, this will be the first ever Danny Phantom and Grossology crossover!
Anyway, this is set after Grossology ended with Night Of The Living Roadkill, and on the Danny Phantom end, this is pre-Phantom Planet. So, after D-Stabilised. Just, so that you readers get a sense of the timeframe. And, Jazz is eighteen, both Danny and Abby are sixteen(I believe that both Jazz and Danny have their birthdays during summer), and Ty is fifteen. Just so you know their ages.
Anyway, I don't own Danny Phantom, that belongs to Butch Hartman, and I don't own Grossology, that belongs to Nelvana. All I own is this story!
Enjoy, and please read and review!

Chapter One
The Announcement
It was a nice, calm, sunny day in Amity Park, Illinois. Not a single ghost was in sight, which was good news for a certain black-haired teenager.
At Casper High, the resident high school, the bell for home rang one final time… and the doors burst open as a flood of cheering students rushed out, and among them a familiar trio.
Tucker Foley, the resident techno-geek, Sam Manson, an Ultra-Recyclo Vegetarian who was also Goth, and Danny Fenton, the son of the town's resident ghost hunters Jack and Maddie Fenton with a huge, ghostly secret, were at the back of the stream of excited students, but they too were cheering; even Sam was cracking a smile here and there.
"Dude, I can't believe it's here! Summer vacation!" Tucker cheered. "No more homework… no more curfews… three fun-filled months ahead!"
"I know the feeling, Tuck," Danny said, his own grin wider than his friend's. "Now that it's summer, there's no homework or assignments or any other school work that I need to worry about, and my mom and dad are lax on my curfew. I can stay out all night fighting ghosts, and my parents wouldn't scold me over curfew or not studying. All I have to worry about this summer, is fighting ghosts, making sure my parents don't rip me apart molecule by molecule or that Val doesn't waste me, and catching up on some much-needed sleep."
Sam and Tucker smiled knowingly at each other, knowing what Danny was talking about.
You see, Danny's secret was that he was half-ghost and the town's local superhero, Danny Phantom. Ironic, huh, that the son of Amity Park's most well-known ghost hunters was half-ghost.
Now, Danny wasn't born with his ghost powers; he had gotten them when he had an accident in his parents' Ghost Portal, a dimensional doorway into the Ghost Zone, home of all things spooky and ghostly. He had accidentally pressed a button, which turned out to be the "On" button, and the portal turned on. It electrocuted Danny with both electricity and ecto-energy. It half-killed Danny, but since the ectoplasm had bonded with Danny's DNA, it protected him from being fully killed and made him half-human, half-ghost. After a month after the accident and having his powers, Danny fought his first ghost, which was the Lunch Lady, and decided from then on to protect his town from the ghosts threatening to take over it, and the world, and who wanted to fully kill him. He had faced some tough challenges in his ghost-fighting life, from his archenemy Vlad Plasmius, AKA Vlad Masters, a fellow human-ghost hybrid, only older and eviler, to facing off against his ultimate enemy, Dan Phantom-AKA, his evil alternate future self, to at first battling against, then with, his "cousin", Danielle "Dani" Phantom, the third human-ghost hybrid in existence who happened to be his clone and one of many in Vlad's attempts to clone him to get his perfect half-ghost son when Danny refused to join him, showing her who Vlad really was which lead her to make the right choice and defect from Vlad's side, and then stabilising her after she came back for help and was almost melted into ectoplasmic goop, to his battles with the Red Huntress-AKA Valerie Grey, AKA his friend and ex-girlfriend, to dealing with Freakshow and the whole Reality Gauntlet incident, when the whole world knew his secret, including his parents, which was now fixed and was almost a year ago, to dealing with the agency known as the Guys In White, who would do anything to capture him and experiment on him and dissect him, to controlling his powers and developing new ones(like his Ghostly Wail and his ice powers). It hadn't been easy the last two years, but with the help of the three people who knew his secret-Sam and Tucker, who were there when the accident first happened and had stuck by him and kept his secret while occasionally helping him out in his ghost fights, and his big sister Jazz, who had discovered his secret during the whole Spectra incident, but didn't decide to tell him until Danny had discovered she knew during his fight against his evil alternate future self, wanting to wait until he told her, and had been a valuable member of the team, even if she had captured him in the Fenton Thermos a couple of times-, he had come out a better person and a better hero, even though his grades had slipped, and he had given up sleep and meals for protecting the town against all spectral threats, and that his parents hated his ghost form, along with Valerie, who had a grudge against him ever since the Axion Labs incident when he tried to stop Cujo and inadvertently caused Valerie's dad to lose his job, and the times he was framed and mind-controlled.
But, since summer was here, he could catch a break and relax for a bit, before his ghost sense went off and he needed to protect the town as Danny Phantom.
And that just made him happy, and even more so since his ghost sense hadn't gone off all day.
"So, what do you guys wanna do since it's the first day of summer? Go to the Nasty Burger, head to the park, catch a movie, visit the arcade?" Tucker asked his two best friends.
"I'm in the mood for a movie. And, I've heard the new zombie film is pretty good. The graphic scenes where the zombies eat people are really realistic," Sam answered.
"Cool. What about you, Danny?" Tucker asked his best friend.
Danny was about to answer when his phone went off. He took it out of his pocket and read the text before typing a quick message back and putting his phone back in his pocket.
"Sorry guys, but I can't for the movie. Jazz just texted me; said that our parents have something to tell both me and her," Danny informed his friends, slightly worried.
Sam and Tucker also shared worried looks.
"Do you think your parents know that you're…" Tucker started and trailed off meaningly.
"I don't think so, but I'll call you guys in case they do know and things take a turn for the worse. But, I think it's just nothing," Danny answered.
Sam and Tucker shared another worried look, but smiled for their friend's sake.
"So… wanna rain check the movie?" Sam asked.
"Sure," Danny agreed. "And guys, relax. I'm pretty sure it's nothing Danny Phantom-related."
"Still, Danny, be careful, in case it is Phantom-related," Sam advised.
"I'm always careful."
"Lovebirds," Tucker "coughed".
"WE'RE NOT LOVEBIRDS!" Danny and Sam yelled, even as blushes spread on their cheeks.
Suddenly, a beeping sound came and Jazz pulled up to the sidewalk in her car.
"Hop in, little brother," Jazz invited.
Danny turned to his friends and said, "I'll be fine, guys. See you tomorrow at the Nasty Burger?"
"Sure, dude. See ya!" Tucker said back as Danny walked to his sister's car, Sam still having a worried look.
Tucker, noticing this, elbowed Sam gently.
"Relax, Sam. Danny will be fine, I'm sure," Tucker assured her.
At that, Sam smiled.
Danny, who was now in the car, asked Jazz, "So… what do our parents want to talk to us about?"
"Don't know. They just told me to text you that they wanted to talk to both me and you and if I could pick you up," Jazz answered as she started the car, before driving it as she pulled away from the curb.
"Do you think they, y'know, found out?" Danny inquired, looking worried.
"I'm sure that Mom and Dad haven't found out. But still, it might be wise to be on guard, just in case," Jazz answered, eyes fixed on the road.
"Then what is it about, then?"
"I… have no clue."
That caused Danny to have a look of worry on his face as he looked out the window.
Silence fell upon the Fenton siblings as Jazz drove back to Fenton Works. Soon, they had arrived.
Jazz parked the car next to the curb and she and Danny walked out and headed to the door, going straight inside. Once inside, they saw that their parents were sitting down on the couch with smiles on their faces, obviously having waited for them.
"Hey kids! Glad that you're here. We've got something big to tell you two," Maddie said.
Danny and Jazz looked at each other before sitting down on the available chairs in the room.
"Uhh… what do you want to talk to us about?" Danny asked.
"It doesn't have anything to do with Danny Phantom, right?" Jazz asked.
Almost immediately, she heard Danny hiss sarcastically, "Smooth. Totally not suspicious at all."
Jazz glared at him.
"No kids. It's not about the ghost boy. It's something else," Jack answered.
Jazz and Danny both let out sighs of relief.
"And that something else is that we're heading out of town," Maddie revealed.
"Phew," Danny and Jazz muttered in unison, slumping in their seats with relief, before their eyes widened and they sat straight back up. "Wait, WHAT!?"
"Look, I know it might sound bad, but we're just going away for two weeks, and then we'll come back," Maddie told them.
At that, Danny and Jazz sat back, before sitting upright again. "Wait, WHAT!?"
"Now, Danny-Boy, Jazzy-Pants, it isn't as bad as you may think. We're just going away from Amity Park for the first two weeks of summer, and then we're coming back,"Jack assured them.
"Oh."
"So…" Jazz started after a period of silence, "where are we going? Los Angeles, Chicago, Boston, New York…"
"Cape Canaveral?" Danny interjected hopefully.
"No, we're not going to any of those places; we're going to see my sister and her family in Charlesberg, Massachusetts."
"Wait… WHAT!?"
"Yep, we're going to see your Aunt Petunia and Uncle Harvey!" Jack boomed, smiling.
"But Mom, Dad, we haven't seen Aunt Petunia and Uncle Harvey in eight years. Not since, you know, the Incident," Jazz pointed out, looking at her parents meaningfully.
"I know, Jazz, and I was surprised as you two are right now when Petunia called me. But, she's eager to see us again, despite the Incident. Wants to reconnect with us, since we're family," Maddie told her.
"But, why?" Danny asked, as he looked at Jazz warily. Even though Aunt Petunia was family, he remembered clearly the last time someone close to his parents wanted to reconnect with them(cough, cough, Vlad Masters/Plasmius, cough, cough).
"Well, she's family. She wants to catch up with us, see how we've been going. Nothing wrong with that," Maddie answered her son. "Now kids, could you go upstairs and start packing for our trip? We're going to be leaving soon."
After she said that, she and Jack stood up and headed for the stairs.
"Uhhh… how soon?" Jazz asked.
"We're leaving first thing tomorrow, Jazzy-Pants!" Jack answered.
At that, Danny and Jazz stood up, eyes practically bugging out of their heads.
"TOMORROW!?"
"Yes, tomorrow, so I advise that you two start packing straight away," Maddie advised, before she and Jack walked up the stairs and to their room to start packing as well.
As soon as they were out of sight, Danny looked worriedly at Jazz and said, "This is bad."
"How can it be bad?" Jazz asked.
"I don't know, what if a ghost attacks while we're gone? What if Ember tries to take over the world through her music or Undergrowth comes back, or Vortex? What if the ghosts come after me while we're away? What if they do come after me, and Mom and Dad discover my secret, much less our aunt and uncle and cousins. Jazz, all of that is bad," Danny answered as he sat down, looking nervous.
"Danny, relax," Jazz firmly told her little brother as she sat next to him. "Danny, none of that's gonna happen, since Tucker and Sam are still in town. And, don't forget Valerie. Besides, we'll pack enough ghost-hunting gear to last the two weeks that we're gone if the ghosts do come after you. And, you've been hiding your secret for two years; I'm sure they're not gonna figure it out while we're visiting our aunt and uncle and cousins. Heck, I didn't figure it out until I saw you transform."
"I know, but… man, this is like Vlad all over again. I know that Aunt Petunia is family, but what if she's evil? What if she and our uncle and cousins are all evil? I can't take that chance."
"Daniel James Fenton, this is not like Vlad. Aunt Petunia, Uncle Harvey and our cousins are family. They're not evil. In fact, just to calm your paranoid brain, they're not even involved in anything ghostly or paranormal; Aunt Petunia's an entomologist and Uncle Harvey's a water treatment worker. They're completely normal. So, calm down, take a few deep breaths, and relax."
Danny did just that, relaxing instantly. He smiled at Jazz. "Thanks Jazz."
"No prob, little brother," Jazz smiled back, before she stood up, smirking at her halfa brother.
"I mean, how abnormal can Aunt Petunia, Uncle Harvey and our cousins Ty and Abby actually be? It's not like they're leading double lives or anything," Danny commented.
"That's true, and probably unlikely, considering how normal Aunt Petunia and Uncle Harvey's jobs are. Now, what should we pack first; clothes, or ghost-hunting weapons just in case?"
…
Meanwhile
At the same time, when the students of Casper High were finally free to go on summer vacation, along with a certain trio, the students of Ringworm High were allowed the same freedom. A similar flood of students poured out of the school, cheering and shouting in excitement at the fact that they were now on summer vacation. Among them, two siblings with a secret of their own like their cousin, except much, much more grosser. Currently, one of them was charging through the students, excitement written all over him.
"YES! Finally; summer's here!" Ty Archer cheered as his sister, Abby Archer, rolled her eyes and smirked, her trademark ponytail swinging slightly behind her.
"And, you know what that means?" Ty asked Abby, grinning knowingly as Abby grinned back.
"Yep, I do," Abby answered.
You see, as mentioned above, Ty and Abby Archer have a secret like their cousin; they were Grossologists, agents for the top-secret government agency the Bureau of Grossology, where they solved disgusting crimes and fought gross villains. Sometimes, it had been tough, and sometimes, it had been impossible, but they managed to defeat the bad guy and their evil schemes, no matter how gross it got.
Of course, nobody outside the Bureau knew about their double lives except for the Detective, which meant getting out of class was tricky business when they were needed to defeat a gross baddie and their evil plans. Which was why they, like their cousin, looked forward to summer. Summer, to them, meant being full-time Grossologists.
"So, who do you think will be behind the first gross crime that we'll receive now that summer's started? Sloppy Joe? Insectiva? Lance Boil?" Ty guessed.
"Hmmm, could be any of them, considering we haven't had a single assignment from the Director all day," Abby said. It was true; the Director hadn't called them once for asking-well, demanding-that they check out the gross crime that the Director had been told about and stop the villain behind it. The siblings didn't know whether to be happy or disappointed that they weren't tracking down any bad guys right now. "But, I'm sure that this summer isn't going to be boring. In fact, I'm positive that the Director's gonna call us right now."
Well, Abby was right about her first prediction; hers and Ty's first two weeks of summer was definitely not going to be boring. Far from it. And, she was semi-right about her second prediction; someone did call her. But, it was not the Director.
Her phone began ringing and Abby pulled it out from her pocket and answered it.
"Hello? Oh, hi Mom. Hmmm. What kind of announcement? Oh, okay. Sure. Yeah, me and Ty will be there. Okay, see you soon, Mom. Love you, bye."
With that, Abby ended the call.
"What was the call about?" Ty asked his sixteen-year-old sister.
"Mom called me to tell me that she and Dad want to talk with us back home. Something about someone coming to visit us," Abby relayed to her brother as they walked to her car; since Abby had received her driver's licence a month ago, she now drove a car, though she still let Ty drive the GRS-1 when they were on missions.
Abby got behind the driver's seat while Ty got in the passenger's seat and said, "Oh, good. For a second, I thought Mom had figured out our secret identities."
"I was worried there too, Ty, until she said that she and Dad wanted to tell us that someone was coming to visit us."
Silence descended on the Archer siblings, until they came to their house. Abby parked her car in the driveway and she and Ty got out and walked up to the front door of the house, heading inside.
Once inside, they found their parents sitting on the couch, smiles on their faces. Casting a look at each other, Ty and Abby sat down as Abby said, "So… what do you guys want to tell us?"
"Well, kids, you see, um…" Harvey started, and Petunia picked up, "You see, Abby and Ty, we're… having my sister and her family come over to stay with us."
At that, Ty and Abby's jaws dropped and their eyes bugged out.
"Wait, WHAT!?"
"Yes, your Aunt Maddie and Uncle Jack are coming to stay with us, along with your cousins. They'll be here for two weeks."
"But Mom, Dad, we haven't seen Aunt Maddie and Uncle Jack since the Incident eight years ago. Why call them to visit us now?" Abby asked.
"Well, Maddie's my sister, and despite hers and Jack's, eccentrics, I want to catch up with her, see how she and her family are since eight years have gone by. I think it was about time too," Petunia answered.
"Oh."
"So… when are they coming here?" Ty asked.
"Tomorrow."
"TOMORROW!?" Abby and Ty exclaimed, standing up, jaws hanging and eyes bugging out.
"Now kids, I know it seems sudden, but Maddie and Jack assured us that they would be here tomorrow in their, uh, Fenton RV. No need to panic," Harvey assured his son and daughter. He smiled and added, "Also, Abby, Ty, I'm sure you'll get along with your cousins. They may not be into the gross science stuff as much as you two, but I'm sure you'll find some things to bond over."
Abby and Ty smirked knowingly at each other. Their parents, much less their aunt and uncle and cousins, had no idea how much they were into the gross science stuff that they were in.
However, that lasted for a few seconds, as their smirks dropped as realisation came crashing in. Their aunt, uncle and two cousins were coming over. Which meant four new people to hide their Grossologist secret from, especially if they were needed to help catch a villain.
Suddenly, family coming over sounded more daunting than it was originally.
"Uhh… great, Mom and Dad. I'm sure me and Ty will get along great with our cousins. Right, Ty?" Abby asked her younger brother.
"Oh, yeah. We'll, uh, get along wonderfully with our cousins," Ty agreed, smiling nervously.
"Great!" Petunia exclaimed happily, before she and Harvey headed towards the guest room. "Me and your father are gonna get the guest room prepared for your aunt and uncle. Abby, Ty, could bring in a blow-up bed each into your rooms? You're gonna be sharing with your cousins."
"Sure thing, Mom," Abby agreed.
Petunia and Harvey smiled at her before they walked into the guest room, getting it ready for Jack and Maddie, while back in the living room, Ty and Abby were freaking out.
"This is bad, Abby. What if Uncle Jack, Aunt Maddie or our cousins sees us go to the secret entrance for the Gag Lab in the shed? What if they see us either talking to Lab Rat or the Director on our grossometers? What if they see us in our slime suits? What if-" Ty started to worry, until Abby said, "Ty, calm down. Neither Aunt Maddie, Uncle Jack or our cousins are gonna discover that we're Grossologists. Sure, there's more of a risk since we're hiding our secret identities from four other people now, but we can do it. We've faced more impossible odds on the field."
"You're right, Abby. But still, it's gonna be hard."
"When has it not been hard? Besides, I think we can handle it. Aside from Uncle Jack's and Aunt Maddie's job, they're perfectly normal, even though our aunt and uncle are a bit eccentric."
"Yeah. It's not like Aunt Maddie, Uncle Jack, or our cousins Jazz and Danny are leading double lives or anything, like us," Ty said, agreeing with Abby.
"The chances of that are pretty low, despite our aunt and uncle's job."
"Yep. By the way, who's blowing up the first blow-up mattress?"
Abby groaned and face-palmed.
Little did she, Ty, or their cousin Danny know exactly what type of double lives the other lead, or how they would intersect…
Yep, I made Ty, Abby and Danny cousins! By making Petunia and Maddie sisters!
Has anyone noticed that Maddie and Petunia look kinda similar, despite different clothing choices, hairstyles and eye colours?
And now, the Fenton family is going to visit the Archers! What's gonna happen, are there going to be misunderstandings where Ty and Abby believe that Danny Phantom is a villain, or will they believe that Phantom and all of the ghost attacks in Amity Park are a hoax? Is there gonna be a villainous team-up between the villains of Grossology and Danny Phantom? And will Ty, Abby and Danny discover the other's respectful secrets? You'll hav to wait and see…
By the way, what's the name of the city Grossology is based in?
Sorry if I made any of the characters OOC. I try not to, but if I did, could you point it out and I'll try to fix it up as best as I can and try to make them more in-character. This is my first time writing a Grossology fanfic, even though it's a crossover with Danny Phantom.
Please read and review! I take constructive criticism, but please, no flames or hate reviews. Like I said, this is my first time writing a Grossology fic, despite it being a crossover.
Enjoy!
