I don't own Danny Phantom or Grossology. They are owned by their respective companies. Though Joe Gutchern is an original character.

It was another day in Ringworm as the people went through their usual routines. Some were enjoying lunch at a cafe or restaurant while others read the newspaper, both paper and electronic. The rest, however, noticed a giant snot monster salmon kg through the streets with a man of an utterly unhygienic lifestyle sat on its shoulder.

"Ahhh~nothing like a nice walk through town to get your daily dose of nuggets. Isn't that right, Franken-Booger?"

The enormous mucus man just roared as he extended sticky, gooey tendrils into the noses of the masses. Sucking up the crusty, gooey, or sometimes runny nose gold, the monster increased in size as he slimed away.

While most people ran from the terrifying sight, the ones who had their runny or stuffy nose picked clean were happy to breathe normally again.

Flying high in the sky were brother and sister Ty and Abby Archer, agents of the Bureau of Grosology, grossologist as they were called, in the GRS-1. And when a situation like this occurred, it was anyone's guess these two would put a stop to such disgusting crimes. Though their identities were kept secret.

The GRS-1 was closing in on the creature as it swatted them with difficulty.

"Remind me again why we let Sloppy Joe keep that thing?" Ty Archer asked while driving.

"Come on. It's his only friend." Abby responded. "What were we supposed to do?"

"I don't know...take it back to the gag lab?" the younger brother answered.

"But you saw how lonely Joe is without him-Look out!"

Ty had managed to dodge another swat from the gooey boogery giant.

"He's dating Insectiva. How lonely can he be?" Ty groaned as Abby readied the built-in goo cannons.

Firing away at the living loogy, the goop was absorbed within the confines of its body as it gathered the goop into its mouth. With a nasally gasp, it lubricated the substance even more and spat it out with great speed, nearly hitting the GRS-1.

"This is going to be harder than last," Abby commented.

"I know," Ty said as he looked around. "Since the city Went green, there's no contaminates that we can use to lure and contain the guy. Mucus is made to absorb this stuff, and he doesn't get any—"

"Then he won't shrink down. I know."

It was true. While it was better for the environment and the people, no smoke stakes meant they needed something else to defeat this gross, gooey, greenish foe.

Flying around, the duo did not have many options. Fortunately, an answer came in the form of tech support.

"Ty. Abby," came a voice from the monitor inside the GRS-1. In a moment, Lab Rat's face appeared as well as a map. "There's a construction site nearby the city. I'll send you the coordinates."

"Thanks, Lab Rat!" Ty and Abby remarked as they flew away from the fifty-foot snot monster chasing them with a loud roar echoing in the city.

As the snot giant followed, the sawdust and other contaminates were absorbed, being filtered inside its body, which dried to contain them. With the mucus drying, the enormous pile of living boogers shrunk down to the size of a small candy bar.

"There we go. Back to a fun-size nugget," Abby said as she picked up the tiny living booger. "Awww! You're just a teeny weeny little guy now, aren't you?"

"Roar!" The booger monster tried to yell, but it came off as a high pitch squeak to the grosssologists' humor.

Sloppy Joe ran up with fury at what he saw.

"What the heck! Why'd ya have to shrink down my little buddy?" The Incredibly filthy man said as he scooped up the Frankenstein booger and ran.

The duo would have given chase, but their communicators went off. Joe would have to wait for now.

Opening the device, the screen blurred to reveal the director, a man whose squeamishness questioned why he would be leading a department of grossology.

"Grossologists!" the director cried from the gagcom. "We have an emergency. People have been reporting a foul smell rotting through the city. Ugh! It smells like...like," the squeamish man held his gag reflex. "It's making people vomit! Just get going!"

"We're on it, sir," Ty replied. "Lab Rat, can you tell us anything about the smell?"

"All I'm getting is news of a terrible odor with people vomiting. But get this, the pattern is like a path."

The gagcom had another screen show the path of people regurgitating.

"Funny it looks to be heading toward the mall," Abby commented.

"I wonder who could be behind this...we just saw Sloppy Joe run in the other direction, and he's nowhere near as fast at the stench is spreading," Ty said, looking in the direction the criminal escaped to.

"Then I guess we'll just have to sniff it out at the mall," Abby commenter with her goo cannon cocked.

They went in that direction, unsure of what to expect.

They were shocked to see what seemed like a mixture of garbage, vile, and any other bodily fluids flying ina messy tarp. They had never seen a ghost, so they didn't know what to make of Joe when they saw him. But they had the words for his odor.

"Feu! That's some stench, buddy," Ty said with his goop cannon aimed. "You might even be on the top ten worst smells."

The spirit paid him no mind but did pause for a moment in reflection. It was the first time Joe hadn't been called the smelliest thing. It was rather refreshing for him. Turning around, Joe wanted to see who could handle his stench. To his surprise, Ty and Abby were dressing in spandex slime suits with goggles, but no mask.

"Well, this is a first," Gutchern commented with glee. "No one's ever been able to stomach my stench. I usually have them passing out. You two are different."

"We're grossologists, buddy. Your stench is nothing for the queen of squeam," Abby said sternly with pride.

Her brother, Ty, rolled his eyes at her self-proclaimed title. While nothing had made her throw up except that one time, it was something well earned.

"We shall see about that," Gutchern said with a grin before he blasted them.

Ty and Abby rolled to the side as they fired shots at Gutchern.

The goo went right through Joe and hit whatever was behind him. The brother and sister duo were shocked to see their weapons had no effect.

"Now it's my turn," the ghost said with a wicked sense of excitement.

Joe's stomach expanded, with his layers becoming transparent as some form of liquid was bubbling inside.

The two siblings rushed forward to interrupt the gross ghost. But it was too late.

"Watch out!" Ty exclaimed as he dodged the incoming filth. The stuff piled on everywhere as it was spewed all over the ground. Citizens who regained consciousness took a whiff of the scent before emptying their stomachs of any snack or meal, adding more to the mess.

"If I didn't know any better, I'd say he's giving away free cow pies," Abby quipped as she started blasting. "Why don't you get a whiff of this!"

She sent a blast to the spirit, which had the same effect as last time, giving their foe no sense of worry. In fact, he was giving a broad, goopy, drippy smile.

"Nice try, but how about I really bring the stench?!" He said before sending a blast at her.

While the two fought valiantly, they were getting nowhere. The spirit was still full of energy while the grossologists were tiring out.

Matters were only made worse when their goop launchers ran out of ammo.

"Uh-oh," Ty squeezed as the launcher "pffft" in emptiness. "Uhhh...Abby?"

"Masks on! We'll take him head-on," the older sister quipped as she donned her gas mask and ran up to the ghost.

"You said my stench isn't much," Joe said with the most giant smirk on his filthy face. "Then try this on for size."

With a guttural roar, he shook and loosened the filth covering him as his stretch grew in folds.

People not committed unconsciously as everyone else ran to escape the horrid, unfathomable odor.

"Whoa!" Abby exclaimed at the force, but she kept her posture intact, along with her nose and stomach. "You just might make Joe seem mild."

At that, the gross ghost gave her a look. He actually seemed offended.

"Different guy."

"Alias is Sloppy Joe," Ty remarked as he had his mask on and used a wrench to open a nearby fire hydrant.

The rushing water pushed Gutchern back as he dissolved and turned into a mushy, squishy pile of dung-like ectoplasm, complete with a horrendous gassy odor that killed the flies that gathered.

"Smells like victory," Abby gloated.

Ty just rolled his eyes as he brought out a claw and took a sample. The readings he got were off the charts. However, all the substance began to reform around in a smelly ball before the face of Joe was seen. This time, his grin was wicked.

"Ok, we're going need more info on this guy," Ty squeaked.

"Gutchern," the ghost said as he floated closer. "Joe Gutchern."

"Uhh...thanks?"

The awkward moment didn't last long as the ghost resumed his disgusting barrage of garbage hoop being thrown into the air. The siblings jumped out of the way as the combined smell rotten fish, compost, and, what seemed to be, fecal matter flooded their noses once more.

"This can't go on," Ty remarked. "While we can handle this smell, our weapons don't seem to do much, and this much garbage, or whatever it is, can't be good for the people."

"We need to get him out of here and clean up the area. But how?"

The answer to Abby's question came in the form of a series of blasts along with a shout.

"Hey! Joe! Remember me!?"

From the skies flew in Danny Phantom carrying some equipment. With beams of ecto-energy aimed at the specter, he was making room between Joe and the grossologists.

With a blaster in hand, the ghost boy fired away, but instead of a laser or ray, foam came from the barrel. It splattered onto Joe like the goop but stuck. A loud hiss could be heard as some of his disgusting exteriors fell apart.

Joe screamed with a loud, "Aaaaaaaah!" as he backed away.

The grossologists were surprised.

"Huh? Where'd he get that?" Ty wondered out loud. He activated his visor, zooming in on the logo printed on the devices.

All they saw was a green F on it.

Gutchern, thinking he had enough, powered through the stream of ecto-foam. While his pace was slow and steady, the funk that fell off him maintained their pungent odor.

The smells lingered as they made their way to Danny. It wasn't long till it reached his nose, causing him to lose focus and wobble his aim.

Holding himself together, the ghost boy grabbed his head, dropping his weapon, and keep on Joe.

Seeing his chance, the gross ghost Decided to charge ahead, bile, and everything rebuilding and reforming along the way.

"Look out!" Abby cried as she ran to the boy. She tried to push Danny out of the way but found herself going through him. Fortunately, the girl had managed to push the device the ghost boy was holding onto, dragging him out of the way.

Lifting Abby, Danny soared out of the way as the two landed near Ty.

"Whoa!" Ty exclaimed.

His sister was no better as she didn't understand why she went through the boy.

But nobody had time to process their thoughts as Joe, angry he missed, flew back as he took a deep breath before spewing out more goopy, gunky vile at his foes.

Thinking fats, Danny produced a shield around him and the grossologists. Though some were deflected, the rest of the ecto-slime stuck onto the down like dried snot under a desk. It hardened and took a gummier like texture as the trio was surrounded and trapped inside.

Joe, seemingly happy with himself, flew way in victory.

"Now, let's see what else has changed," he said. "But first, a little pick me up."

Inside the dome, the grossologists turn to the ghost boy in a stunned fashion.

"What was that?!" Ty asked Danny, who kneeled down. "with the flying and blasting and...this shield!?"

"Ty," Abby tapped her brother on the shoulder.

"I mean, how is this scientifically possible?"

"Ty."

"Our weapons barely did anything, but you hit him and-"

"Ty!"

The boy now noticed Danny almost heaving on the ground. His face was greener than anything around them, even his ectoplasm.

"I don't get it. It smells like the normal filth we deal with," Ty remarked, sniffing the air before it dawned on him. "Oh..."

"Yeah," Abby said as she threw a punch at the dome. With a small crack, the crust of the prison gave way to a going center that dripped inside with a gelatinous feel.

It served to make Danny greener as he struggled to stand up.

"How can you guys fight stuff like this?" Danny finally spoke. "Who are you?"

"We're grossologist," Abby answered as she and Ty examined the walls from a way out. With their goop cannons empty, no one could blast their way out.

"Never heard of you," Danny replied as he mustered all his strength to get up. The smell was nauseating. "anyway, let's get out of here."

"How? The walls are like a mix of snot, gum, wax, and whatever else our scanner's aren't picking up," Ty had his claw scanner out, trying to get a sample.

Danny didn't say a word but picked up the brother and sister before phasing them out of the makeshift prison. The ghost boy let go of the grossologists and took a deep breath, happy to be out. Though the smell outside wasn't that much better from the mess, Joe left.

"Great," Danny groaned.

The grossologists saw...or smelled it and realized that things are getting worse.

They also realized that they need this ghost kid's help.

"Come on! We'll explain at the Gaglab," Ty said as he and Abby walked to the GRS1. Danny followed though he had one question along the way.

"What the heck is a gaglab?"

And Danny meets Ty and Abby under most disgusting circumstances. though given the brother and sister's job, that's an understanding.

Special Thanks! to Flower Princess11 for all her help!
