Meanwhile, Shaggy and Scooby were in the basement, looking scared, and Scooby even whimpered. The two shivered nervously as they explored the basement. As they were walking, Scooby stepped on a familiar looking tail: it was the Hyde Hound's tail who was asleep.
"Like, zoinks!" Shaggy yelped.
"Shaggy?" Earl called.
"Scooby-Doo?" Flem called.
"Where are you?" Chicken called.
"They could be anywhere." Trixie sighed.
"You guys, I heard something," Katrina said as she heard a noise coming from a mile ahead of them. "Follow me."
The others then followed the werecat over to where she heard the noise. Shaggy stepped on the bucket filled with water, and the mop landed on his head. Scooby was juggling light bulbs so they don't hit the ground and the cowardly Great Dane landed on top of his best friend. Luckily for them, the Hyde Hound was fast asleep.
"There they are." Katrina told the others.
Gleek looked over and yelped as he saw the Hyde Hound and climbed up to Zan's shoulder in fright.
"Shh... Be very, very quiet." Trixie told the others so they wouldn't wake up the Hyde Hound.
"Don't move either." Katrina added.
Gleek shivered while biting his nails.
"Don't breathe... Don't blink... Don't move..." Chicken said in stunned fear like in the Five Nights at Freddy's musical starring famous YouTuber: Markiplier.
Meanwhile, Becker was checking the security monitors again. "Hmm..." The man hummed to himself in thought.
"Mr. Becker?" Velma called out.
"Aaaugh!" Becker screamed before glaring. "I already gave you kids all-access passes, why are you back here, exactly?!"
"Because Mr. Becker, this is very serious." Cindy said as she handed him a Blue Falcon video tape.
Becker took the case with a scoff once he saw what it was. "Quite frankly, kids, uh, I don't have time to determine some slime that turns people into monsters," he then tossed the tape back and Fred caught it as he watched the security cameras. "I still gotta catch the clowns who ate all the best food!"
"Is that all you even care about?!" Buttercup glared as she grabbed Becker by his shirt. "Someone EATING ALL THE FOOD WHEN THERE ARE LIVES IN DANGER?!"
Cindy was about to get in the middle of this, but realized who was involved and decided to back out.
"Let go of me!" Becker told the raven-haired Powerpuff Girl.
Mike grabbed the toughest Powerpuff Girl away from Becker.
"LET GO OF ME!" Buttercup snapped.
"Heel, Buttercup, heel!" Mike told the girl.
"Lemme at him!" Buttercup demanded as she tried to punch the air while Mike held onto her.
"Sorry about that, sir," Mike told Becker. "I'll get her to cool down."
"See that you do." Becker nodded.
"Buttercup, take it easy." Mike told the girl.
Buttercup growled, but soon calmed down only because Mike told her to.
Meanwhile, back with the other group...
"This is scary," Flem commented. "I vote to get out of here."
"Hey, gang, there's another room there!" Earl pointed out to a door.
"Let's find out," Jayna suggested. "Come on, guys!"
Everyone then followed after the female Wonder Twin. Jayna held Gleek nice and tight as they came inside to explore the other room.
"Kinda looks like the lab in Pinky & the Brain." Trixie commented.
"Jumping Jupiter!" Zan gasped. "Where are we?"
"This must be Mr. Hyde's lair." Shaggy guessed.
"Uh-oh..." Scooby moaned.
"He's got all kinds of floor plans of the convention, and even street maps." Earl pointed out.
"But why?" Flem asked.
"Like, I have no idea, you guys, and why's this one marked Alternate Emergency Route?" Shaggy wondered himself.
Gleek looked over to saw blinking lights in the room and tapped the Wonder Twins.
"What is it, Gleek?" Zan asked the blue monkey.
Gleek pointed to the blinking lights. Shaggy went with the others and nervously opened the door. They saw Mr. Hyde and Dr. Fear in there, getting ready for their next attack and they saw lion and bear creatures, standing guard. Dr. Hyde laughed as he took out his gun and shot a mannequin with a ball of slime.
"Zoinks!" Shaggy gasped. "That's the Psycho Ooze, remember? From Episode 22!"
"It turns people into monsters!" Scooby added.
The lion creature growled and pointed at the others.
"What? Spies?" Mr. Hyde replied. "Intruders?!" He then shot a gun and the others managed to dodge it.
"Attack them!" Dr. Fear commanded.
The lion and bear creatures then went after them as well. Everyone soon ran as they were being chaed. Mr. Hyde shot his slime gun while the lion and bear creatures chased them.
"I got an idea!" Trixie said before she did hand signs. "Shadow Clone... Jutsu! Transform!"
In a poof of smoke, there were suddenly clones of the others. The creatures soon went after the clones.
"Ruuuun!" Trixie told the others.
"Destroy them all!" Dr. Fear commanded. "We gotta find the real ones."
The bad guys and the two mutant creatures were destroying the clones that go away in another poof of smoke.
"Thanks, Naruto," Trixie smiled to herself. "Now for my next attack, I hope I get it right."
The bear creature was attacking the clones from left to right.
"Hey, Smokey!" Trixie called out.
The bear looked over and saw the real Trixie and her clone were making a swirly blue energy ball.
"Eat this! Rasagan!" Trixie called out as she jumped up and hit the bear creature in the stomach with her attack.
The bear growled from the impact and fell to the floor.
"You're as threatening as the Pokemon known as Teddiursa!" Trixie taunted.
The lion creature soon roared as he was right behind her.
"Look out!" Chicken warned Trixie.
Jayna rushed over and kicked the lion over to the side.
"Thanks!" Trixie beamed.
"What're friends for?" Jayna smiled.
Trixie smiled back.
"Where's Shaggy and Scooby?" Jayna asked.
"Up there!" Trixie replied as she pointed to the cowardly duo going up the stairs.
Flem and Earl panicked as they decided to join Shaggy and Scooby.
The four were soon outside on the roof.
"We're trapped!" Flem panicked.
"What do we do now?" Earl asked.
They heard Mr. Hyde and Dr. Fear's laughter and saw them with their guns.
"To those foolish enough to spy on us-" Mr. Hyde began.
"Taste the oozing chaos of fear!" Dr. Fear finished.
Mr. Hyde laughed as he shot more and more slime against Shaggy, Scooby, Flem, and Earl.
"Like, don't let it hit you guys!" Shaggy yelped.
"Yeah, I don't wanna be turned into a monster just like Zan had!" Flem agreed.
"This is scarier than the camp out when Cow came over to give Chicken his hairbrush!" Earl panicked. "And then Bigfoot took all our food!"
Meanwhile with the other group...
"Please, Mr. Becker," Cindy begged. "You have to listen to us... The threat is real!"
"Too real, look!" Fred added as he pointed to one monitor. "There's Shaggy, Scooby, Flem, and Earl!"
"And Mr. Hyde and Dr. Fear!" Trent added.
"We gotta do something!" Brianna cried out.
"Hey, where did Mike, Sammy, Phil, and Lil run off to?" Cindy wondered.
"There's no time to worry about that," Becker replied. "Come on!"
They all then went off to help the others as this was anything but good.
Dr. Fear and Mr. Hyde laughed as they kept shooting the four.
"You guys, this way to the big balloon!" Shaggy suggested.
Everyone then rushed to climb onto the Frankenstein Jr balloon. Once they all made it up, Shaggy and Scooby took the ladder away to keep Dr. Fear and Mr. Hyde from climbing up it after them.
"You can't get us!" Flem and Earl mocked and made funny faces.
The villains kept shooting at the four who were dodging the attacks.
"Like, we gotta get to higher ground, you guys." Shaggy said.
"What could be higher than this?!" Earl panicked as they ran off.
"Hey, ugly!" Trent called out.
The villains turned around and saw Fred, Daphne, Velma, Brianna, Trent, Cindy, Courtney, Buttercup, Chicken, Katrina, Zan, Jayna, Gleek, Trixie, Becker, and the guards.
"You leave them alone!" Cindy demanded.
"Fools, you cannot stop us!" Dr. Fear laughed.
Mr. Hyde soon snapped the balloon rope in half and rode off with the now flying Frankenstein Jr balloon.
"They're getting away!" Courtney yelped.
Buttercup growled and flew up there to stop the two villains.
"I'm glad I ain't up there." Chicken said nervously since he was afraid of heights and flying despite being a bird.
"You cannot escape us!" Mr. Hyde laughed as he jumped onto the balloon with Dr. Fear.
"Looks like those guys are in need of some serious pest control." Cindy said.
Buttercup soon glared as she zoomed down to beat up the villains.
"And here she comes now!" Cindy announced.
"I'm gonna make these freaks cry for their mommies!" Buttercup promised darkly.
"And who might you be?" Dr. Fear scoffed at Buttercup.
"I'm Buttercup: The toughest fighter of the Powerpuff Girls." Buttercup announced with a glare.
"Well then, little girl, prepare to become a monster." Mr. Hyde mocked as he shot his weapon at the Powerpuff Girl.
Buttercup glared as she avoided the slime blasts and punched them back which sent the slime flying everywhere.
"You're tough, young one, but you shall watch as we turn all of the town into hideous monsters." Dr. Fear mocked.
"Not if we have anything to say about that." Buttercup replied.
"We?" Mr. Hyde asked.
"NOW!" Buttercup signaled.
A shadow came up to the balloon, revealing to be Action Girl, Dark Queen, Moon Shadow, and Supergirl.
"Not you freaks again," Dr. Fear huffed. "Don't you have anything else better to do?"
"Yeah? Kicking some action!" Action Girl replied before lunging out for him with Moon Shadow.
Mr. Hyde backs up and bumps into Supergirl and Dark Queen. "Hello, ladies," He then greeted. "Watch as the town will become monsters."
"I don't think so, Dr. Fear." Supergirl glared.
"Oh, no? Watch this." Mr. Hyde replied as he soon pulled out bombs and threw them into the town which made people run away from them.
"Oh, no!" Supergirl panicked and went to save the innocent townspeople.
"You're going to pay!" Dark Queen glared.
"I think not!" Mr. Hyde glared back as he shot green slime at her.
"Oh, no!" Moon Shadow gasped. "Sis!"
"YOU MONSTER!" Action Girl snapped.
Dark Queen came out with a smirk as she didn't change into a monster.
"What?!" Dr. Fear snapped. "How come you didn't change into a monster?!"
"Because your formulas don't work on people like me!" Dark a Queen smirked. "In Episode 46 when Action Guy teamed up with The She-Wolf when you plotted revenge after your life sentence for mutating those orphans!"
"And in Episode 55 when you changed people into werewolves and Action Guy and The She-Wolf stopped you again." Action Girl added.
"If it doesn't work on you, then maybe it'll work on your brother." Dr. Fear growled at Dark Queen.
"It's the end, you guys!" Flem panicked. "They're all gonna be monsterified!"
"I never got to have my braces taken off!" Earl cried out in dismay.
"Huh? Over there!" Scooby said before pointing to City Hall.
"City Hall!" Shaggy realized.
"You mean we gotta jump?" Earl asked.
"No, we're going to take you there." Action Girl promised.
"Hang on." Dark Queen comforted.
Everyone clung to the heroes as they got off of the Frankenstein Jr balloon.
"You can hide from the view, but you cannot hide from Mr. Hyde and Dr. Fear!" Mr. Hyde glared before opening up his cloak which made bats fly out. "Go, my lovelies, seek them out!"
The bats soon attacked the wall that Shaggy, Scooby, Flem, and Earl were hiding behind.
"Like, he's gone batty." Shaggy commented.
"We gotta do something!" Buttercup cried out.
"I got it, but I need concentration." Action Girl told the others.
Everyone then stayed quiet so that one of the greatest heroes of Cartoon Network City could focus.
"And now, for the finishing touch!" Dr. Fear called out.
Action Girl closed her eyes and opened her eyes as they turned red and the skies became cloudy.
"Huh?" Cindy asked. "What happened to the sun?"
"Cindy, don't scream." Brianna told the usually cowardly girl.
"I'll try." Cindy said.
Action Girl snarled and soon began a new power that no one had yet ever seen before.
"What?!" Dr. Fear called out.
"What's going on here?!" Mr. Hyde demanded.
"What exactly is happening?" Supergirl asked herself as not even she knew what Action Girl was doing.
Action Girl zipped down in front of the four cowardly people, glaring at the villains. "So, you like bats, huh? Why don't you try on my pets for size then?" she then mockingly asked.
Everyone's shadow came life and morphed into wolves made out of shadows and had beady red eyes.
"Whoa..." Buttercup whispered in awestruck.
"Awesome." Dark Queen added.
"Impressive." Supergirl agreed.
"Mega awesome!" Moon Shadow beamed.
"Wow." Flem and Earl said in unison.
Action Girl snarled at Dr. Fear and Mr. Hyde as her power took over. The shadow wolves attacked the bats and the green slime came like a tsunami.
"Run!" Earl cried out.
"It's a Psycho Tsunami!" Shaggy yelped.
Flem, Earl, Shaggy, and Scooby ran to the door to avoid the flood of slime while Action Girl was attempting to hold off the chaos with her newly discovered power.
"Come on," Supergirl suggested. "We better follow them."
"Right." Dark Queen agreed.
They even ran down the stairs and the slime still followed them.
"Gangway!" Scooby cried out.
"Oh, I wish I could help, but I'm just me..." Cindy sighed. "Too bad I'm not a superhero like the others."
The four were soon trapped and they knocked on the door.
"Open up!" Earl cried out. "Ooze Alert!"
The janitor didn't hear them as he was vacuuming and listening to music on his headphones.
"Help!" Flem cried out.
The slime then splashed down and was about to get them at the door. Shaggy, Scooby, Flem, and Earl screamed ducked out of the way to avoid the slime tsunami, and continued to run down the stairs.
"Hurry, you guys, we're not fast enough!" Shaggy cried out. "Quick, jump!"
They all then jumped onto the banister as the slime was spreading everywhere.
"Like, whatever happens, don't let it touch you, guys!" Shaggy told the others.
"Guys, it's rising!" Scooby gulped as the slime was rising up from the stairs.
"What are we going to do?" Flem asked.
"The next best thing," Earl said before yelling. "HEEEELP!"
Busting out of the wall was Supergirl, Buttercup, Moon Shadow, and Dark Queen.
"Like, we're saved!" Shaggy cheered.
"Come with us if you wanna live." Buttercup told the others.
"Like, you don't have to ask us twice!" Shaggy replied.
"Go, go!" Scooby called out as he jumped into Moon Shadow's arms.
"And like, hurry!" Shaggy added as he jumped into Dark Queen's arms.
The heroes then helped the scared ones out of the slime filled building.
In the Mayor's Office, the press was talking to him about the situation...
"Have no doubt, my friends," The Mayor smiled. "We will get to the bottom of this Dr. Fear and Mr. Hyde nonsense, until then, I assure you everything is under complete control."
The press then took pictures of their beloved mayor. The phone then rang and the mayor answered it.
"Yes?" The Mayor smirked.
"Hey, uh, this is Becker, Mr. Mayor," Becker said on the phone as he walked with the others downtown. "Hyde and Fear were just sighted flying over City Hall! You may be under attack!"
"Well, now, I wasn't expecting that..." The Mayor said as he hung up the phone.
The press still continued to take pictures.
Moon Shadow, Supergirl, Dark Queen, and Action Girl helped Shaggy, Scooby, Flem, and Earl out as the slime was flooding the building.
"Maybe we can climb our way out of this." Shaggy suggested.
"Maybe not," Buttercup replied. "I don't want to become a monster."
"Moon Shadow and Dark Queen, you guys are the only ones who are immune to this," Supergirl said to the werewolf twins. "Maybe you can find a way out of this since Action Girl isn't here."
"I don't know, I-" Dark Queen began before she fell down after slipping into the ooze with Shaggy, Scooby, and her twin brother.
"Guys, we gotta help 'em!" Supergirl yelped.
Buttercup, Supergirl, Flem, and Earl fell into the ooze as well. Shaggy and Scooby gasped as they came out of the ooze.
"Scooby!" Shaggy cried out.
"Shaggy!" Scooby cried back. "I've been oozed!"
"I think I swallowed some." Earl moaned.
"Um, guys?" Supergirl spoke up.
"Oh, no, they've turned Buttercup into a monster!" Flem panicked. "A freak!"
Buttercup shook the ooze off of herself. "Ugh! I hate pistachio!"
"Wait..." Dark Queen said.
"Did you say pistachio?" Moon Shadow asked.
"This isn't Psycho Ooze!" Buttercup glared.
Meanwhile, the press was leaving the mayor's office...
"Sorry to cut this short, folks, but something's come up," The Mayor told the people. "And I have to go, uh, to the bathroom..."
The press then left and the mayor shut the door behind them.
"City Hall under attack?" The mayor muttered to himself before opening the door. "What next?"
Then suddenly, a wave of slime hit him and the ooze filled into the mayor's office and broke the doors open, sending everyone riding in a slime wave, and it sent them out of the elevator after it was opened.
"This is so gross." Dark Queen winced.
An old woman walked by the statue with files in her arms and then screamed once she save the ooze wave coming toward her. The woman dropped everything and climbed to the statue as the ooze was rising.
"This is worse than the Kids Choice Awards slime cannon!" Moon Shadow cried out.
The ooze was even coming outside of the City Hall, covering everyone in slime.
"No, Scooby, no!" Shaggy panicked for his best friend.
"Oh, no, Earl, not you too!" Flem yelped. "You've turned into a hideous monster!"
"In the name of ham and rye, our friends, you shall be avenged!" Shaggy bravely promised.
"It's just, it's too, it's too horrible!" Flem and Shaggy cried together only for Shaggy to see that the slime covered mess he had was not Scooby, but the Mayor.
"Uh, you guys?" Earl spoke up.
"I'm sorry, you guys." Shaggy replied.
"Me too," Flem added. "I'm sorry that you are so incredibly hideous looking."
"Shaggy, we're right behind you." Scooby said.
"Scooby-Doo?" Shaggy asked as he looked behind him.
"Earl, is that you, buddy?" Flem added.
The two then realized their best friends were all right which relieved them very much.
"Like, you're all right!" Shaggy smiled. "We're not monsters!"
"Uh-huh." Scooby nodded.
"Of course you're not monsters," The Mayor scoffed before shoving Shaggy, Scooby, and Flem away from him. "You're nitwits!"
"Nitwits?!" Dark Queen glared. "WE JUST SAVED YOUR LIFE AND THIS IS WHAT WE GET?! WHY, YOU-"
The others soon came down the stairs as Moon Shadow did the best to calm down his twin sister before she would go crazy on the mayor.
"But the Psycho Ooze?" Flem remembered.
"You Mystery Incorporated Nimrods are fired!" The Mayor snapped.
Everyone else gasped while Shaggy whimpered.
"And you four are supposed to be heroes," The Mayor scolded the superheroes. "Well, none of you did a very good job!...Wait, weren't there five of you?"
"Let me at him! Let me at him!" Dark Queen growled until Moon Shadow restrained her. "LET ME GO, I WANT HIM FOR MY DINNER!"
"Did Action Girl make it out okay?" Moon Shadow asked the others. "I feel bad for leaving her alone with those two baddies."
"Where is she?" Dark Queen asked sadly. "YOU LEFT HER ALONE?!"
"Now, now, take it easy, Li-Erm.. Sis." Moon Shadow said nervously.
"WHAT DID YOU DO THAT FOR?!" Dark Queen snapped.
"Because she told me to," Moon Shadow defended. "She said she could handle it."
"But she's all alone!" Dark Queen replied. "If anything happens to her, I'll-"
"RELAX!" Moon Shadow told her. "She's been doing this longer than we have, we can trust her, and I know you do since you've been together for so long."
Dark Queen just glared and noticed that the press was looking on the roof as they seen a figure standing there. "What are you guys looking at?" she then asked.
"Up there..." A photographer pointed up to the roof.
"Look up there, it's her!" A newslady added. "Here, in our town, I can't believe this!"
"I can't see!" Cindy jumped up and down. "Ugh... Curse my short stature. Trent, can I get on your shoulders, please?"
"Sure, Cindy." Trent allowed.
Cindy smiled and got on his shoulder and looked up as well and gasped.
"Can ya see, Cindy?" Trent asked.
"Yep," Cindy nodded. "Thank you, Trent."
"It's Action Girl." Brianna told the others.
"Huh?!" Dark Queen asked out of shock.
This was soon on the news.
"In a quirky trust of the Mr. Hyde and Dr. Fear story, City Hall was flooded with strange ooze that later turned out to be a harmless pistachio flavored foam." The reporter reported.
"It's just terrible what happened," Jennifer said as she was being interviewed. "And for this happening to take place during the Mega Mondo Pop-A-Con Palooza, it would've ruined everything. That's why due to the increased danger levels, not to mention the increase in demand for tickets, the Blue Falcon movie screening will not be held at the Convention Center. It will be screened in the San De Pedro Baseball Stadium across the street," she then sent a glare to her assistant. "Andrea, why are you just standing there around?! Go get my lunch now!"
"Yes, ma'am!" Andrea replied as she dashed off just to do that.
"On a lighter side of this story, check out the four so-called investigators who actually thought they were turning into monsters," The reporter smirked as he took turn with the camera. "This security footage actually posted on YouTube."
There was then a YouTube video shown of Flem, Earl, Shaggy, and Scooby freaking out about the Psycho Ooze which was actually just pistachio foam.
"And on the other news the five greatest heroes from Nicktropolis and Cartoon Network City arrived at San De Pedro, but are they really heroes?" The reporter continued.
