"Sorry for tight squeeze," Batman told his passengers. "We're almost there."
"It's all good; except for the Baterang I think I'm sitting on." Shaggy winced.
"Try not to shift your weight then," Batman warned. "Could be an exploding one."
Shaggy and Scooby gulped nervously to that.
"Where are we headed, Batman?" Zan asked.
"Someplace we can lie low until we can clear your names." Batman replied.
"And yours and Shadow Wolf's," Velma added. "By helping us, you've become fugitives yourselves."
"It wouldn't be the first time." Shadow Wolf muttered.
"Oh, don't remind me." Batman said to Shadow Wolf before a rock opened up to reveal a secret door.
Everyone looked around and they were soon drove into the Bat Cave.
"Jinkies!" Velma beamed. "We're in the Bat Cave?!"
"As in the actual Bat Cave?" Daphne added.
"Based on the bat guano I just stepped in, I'd say yes." Velma groaned.
"Maybe that was Ace the Bat Hound." Paulina smirked innocently.
"Wow!" Courtney gasped. "This place is amazing!"
"I know, right?!" Velma agreed.
Shaggy stood up before plucking the Baterang away from his pants, and tossed it away. "Better."
KABOOM!
"Uh, oops..." Shaggy nervously said to Shadow Wolf and Batman.
Batman and Shadow Wolf just gave him a annoyed look.
"We have some investigating to do," Batman told his guests. "Please, make yourselves at home."
"Like, it definitely has the whole cave thing going for it, but the giant penny and dino don't exactly scream 'Bat'." Shaggy commented.
"You have a point, Shaggy, but check this out." Paulina said as she saw a glass case filled with costumes inside.
"Wow!" Fred gasped. "Batman's first uniform!"
"And Robin: The Boy Wonder." Velma added.
"Batgirl's got the cutest cape ever~" Daphne smiled.
"Like, those flashy threads can only be Nightwing's." Shaggy commented.
"And this belongs to Batwoman." Courtney said as she found a gray uniform with a cape and utility belt.
"This must belong to the Red Hood." Trent said as he found a uniform that was a black suit with a brown jacket and a red face mask.
"Look, Scoob," Shaggy found Ace the Bat Hound's uniform. "Who knew Batman had a dog?"
"I did." Scooby giggled.
"I told you guys, it's Ace the Bat Hound!" Paulina smiled. "These are all Batman's sidekicks!...Except maybe Shadow Wolf of course."
"Former sidekicks." Batman corrected as he typed on his computer.
A news theme was then heard playing.
"There, The Press Report." Jayna noticed.
"Detective Bullock, you can't actually believe Mystery Incorporated is behind these crimes." A man said.
"This all started right after they arrived in Gotham!" Bullock defended. "This time, we got it all on camera."
This made the others gasp in shock and dismay. The camera shows Shaggy stealing two tubes.
"Norville Rogers, better known by his gang as Shaggy." Bullock told the people.
"Shaggy?!" Everyone else gasped.
"Norville..." Shadow Wolf chuckled under her breath.
"There you have it, folks, undeniable proof that Mystery Incorporated is guilty of-" A female voice said only to be muted.
"He really has his trademark slouch." Fred commented.
"And his tooth pick arms." Daphne added.
"And his soulless beady eyes." Scooby even agreed.
"Like, okay, we get the picture!" Shaggy glared. "But it's not me!"
"Of course not; there's no possible way that's Shaggy," Velma defended. "He walked right past a box of donuts."
"You don't suppose that Detective Bullock and his men could be...?" Fred was about to suggest.
"No, stay here," Batman told him. "It's too dangerous for you kids to be out on the street."
"Where are you going?" Brianna asked him.
"Back to where this all started: Milo's lab," Batman replied. "Something about that event still doesn't add up."
"So, let's go-" Shadow Wolf said, about to join him.
"No, you need to stay here too." Batman told her.
"But why?" Shadow Wolf asked.
"I don't want anything to happen to you just like Leo Scarlet." Batman replied.
"You mean we have to stay holed up in this cave without sustenance?" Shaggy asked.
"Or anything to eat?!" Scooby added.
"There's a supply of food in the-" Batman was about to say, but once the word 'food' was brought up, Shaggy and Scooby dashed off. "The Bat Dehydrator."
Unfortunately, it had been shrunk.
"It's been shrunk!" Shaggy cried out. "What horrific device could do this to food?"
"It's evil!" Scooby added. "Evil, I tell you!"
"It's a food dehydrator, take it or leave it." Shadow Wolf told the cowardly duo.
"She's right; it allows me to eat hydroponic meals to go." Batman said before eating the tiny steak.
The cowardly duo then took the food and ate it.
"It's like eating a full course meal." Shaggy smiled.
"In one moisture free bite." Scooby added.
"Just don't end up like that gum kid from Willy Wonka." Courtney warned.
"Ugh... I've never eaten so little, and yet feel so full." Shaggy groaned.
"Oh, instant gluttony." Scooby added.
Batman rolled his eyes and then walked toward the Batmobile.
"But Batman, we want to help." Jayna told him.
"This mud isn't made into the area," Batman said as he brought something out and Velma soon caught it. "Find out where it came from."
"You're letting me use the Bat Lab?!" Velma gasped.
"Of course, we are partners after all," Batman smiled before getting into his car. "Shadow Wolf, you're in charge."
"You got it, Bats," Shadow Wolf saluted. "And be careful."
"Don't worry, I will." Batman replied before he drove out of the Bat Cave.
"Jinkies!" Velma gushed.
"What does that word even mean?" Jayna wondered while Arceus just shrugged.
"It sounds like some kind of breakfast cereal." Courtney replied.
Shadow Wolf soon went to sit down. "I sure hope he'll be all right on his own." she then muttered to herself about Batman going off on his own, even without her this time.
Kala went over and hugged her girlfriend as comfortingly as she can. "It's going to be okay, I'm sure he's going to be fine." she soothed.
"He usually is..." Shadow Wolf admitted. "I mean, he has to be when I can't be there with him."
"You look tense." Kala observed.
"I always am, Babe, I..." Shadow Wolf replied until she then looked relaxed as Kala gave her a shoulder rub.
"You shouldn't worry so much, it'll make you sick..." Kala soothed. "My Uncle Tito always said 'The Ancient Hawaiians used to say, don't worry, be happy'."
"I think that's a Bob Marley song." Shadow Wolf smirked.
"How are you feeling now?" Kala asked.
"Back rub, please." Shadow Wolf replied.
Kala nodded and continued the back rub to relax Shadow Wolf.
"Oh, yeah... Yeah... That's so much better..." Shadow Wolf relaxed before she soon whined like a wolf pup.
"Did you just whine like a wolf pup?" Kala squealed. "That's so adorable!"
"Shut up!" Shadow Wolf covered her face as she blushed with a smirk.
"You did, that's so adorable!" Kala replied. "Come on, do it again!"
"No!" Shadow Wolf covered her face shyly.
"Pretty please for your Pineapple Princess?" Kala pouted.
"I can't just do it because you asked me, it just happens..." Shadow Wolf shrugged.
"Aw, man," Kala then pouted out of defeat. "It sounded so adorable when you did that."
"Sorry, it's just something that happens, I don't know what to tell you, you can try again." Shadow Wolf shrugged.
Kala gave Shadow Wolf another back rub so that she would hear the whine noise again, and soon enough, she did. "That is the most adorable noise I've ever heard!" she then beamed.
"Stop it," Shadow Wolf muttered while blushing. "You're gonna make me sound like a puppy."
"But it's really adorable though!" Kala defended. "Just like a wolf pup... That's so adorable."
Shadow Wolf just sighed and shook her head. Trent and Brianna passed by with chuckles toward Kala and Shadow Wolf.
"What are you laughing at?" Shadow Wolf gave them a death glare.
"Oh, nothing." Trent and Brianna replied innocently.
"I'll show you nothing..." Shadow Wolf threatened as she shook her fist.
Trent and Brianna covered their mouths, but still snickered. Shadow Wolf just rolled her eyes.
"So, um, Batman had a dog, huh?" Trent asked as he looked to the display case of Ace the Bat Hound.
"Sure did." Shadow Wolf replied.
"What ever happened to him?" Brianna asked.
"Long story..." Shadow Wolf replied.
"Oh, man, he's not dead, is he?" Brianna grimaced.
"Huh? Oh, no, nothing like that," Shadow Wolf chuckled. "He's actually with The Dog Star Patrol."
"Dog Star Patrol?" Trent repeated. "I heard about those guys; I think that Krypto the Superdog is also a member."
"He is," Shadow Wolf replied. "I always saw it as The Justice League for dogs."
Velma took some of the clay and put it underneath the microscope. "Now to see if I can identify the soil from this foot print." she then said to herself.
Once her back was turned, the soil seemed to slither away, almost as if it were alive like Flubber. When she turned around, she noticed that the soil went back to the foot print.
"Oh, okay, that was weird..." Velma said before she turned around and the soil ran off. "Guys? Something strange... Is going on..."
The soil soon morphed into a monster which made her scream and run off.
"Jeepers! The mud's alive!" Daphne gasped before ducking as the monster threw sludge toward her. "But how?!"
"Who cares?" Courtney replied. "Let's get out of here!"
Gleek yelped and ran away with the girls, running past Shaggy and Scooby who screamed and ran away as well.
"So, like, we're in a battle with possessed dirt?" Shaggy asked.
"Clearly, the chemicals in the stolen isotope spilled into the ground resulting in stimulation of the silicon particals which-" Velma tried to explain before giving up. "Ah, who am I kidding? There's no rational explanation for this!"
"I don't think even Mary and Ellody could crack this one." Jayna said to Velma.
"Or the Test twins." Zan added.
"Probably not even Dexter." Trent agreed.
"What the-?" Shadow Wolf asked. "What's going on?!"
"A mud monster is chasing us!" Daphne told her. "Help!"
"So, like, we're in a battle with possessed dirt?!" Shaggy asked.
"Yes!" Paulina replied. "Keep running!"
"This mud looks familiar, though I can't pinpoint it." Shadow Wolf said to herself in deep thought.
The monster was then throwing mud at the group.
"It must be linked to the case somehow." Fred hunched.
"You think?" Scooby replied.
The monster snarled as it chased them.
"We need Batman!" Jayna cried out.
"Oh, I hope that he's doing okay." Paulina hoped.
"Me too." Courtney agreed.
Meanwhile, Batman woke up tied up with Aquaman.
"Awaken, Batman," The Crimson Cloak demanded. "You wouldn't want to miss the final moments of your life."
"Leo, listen to me, I-" Batman tried to explain.
"Leo is gone, there is only The Crimson Cloak!" The Crimson Cloak snarled.
"I'm sorry," Batman told him. "Let me help you."
"Too late," The Crimson Cloak replied. "You didn't save me, and no one will save you, behold, I have prepared what you destroyed." He then pulled down a lever.
The machine was then turning on, causing Aquaman to wake up, looking at the Dark Knight then at The Crimson Cloak who was groaning in pain for some reason.
"Suffering sand dollars!" Aquaman exclaimed. "I know you're a ghost, but pull yourself together!"
"Great Scott, that's it!" Batman added. "How could I not had known?"
Back with the others...
A lot of the others hid away and shivered nervously from the mud monster.
"Fred!" Daphne and Velma shook their leader. "Plan?!"
"Okay, okay," Fred replied. "Shag? Scoob? You're-"
"The bait?" Shaggy and Scooby replied in deadpan. "Shocker."
The mud then dripped onto their heads. Shaggy and Scooby screamed at that before jumping up in the air and running off. The mud monster then chased after them until it then ended up in the dehydrator.
"Turn the dehydrator on!" Trent called out.
Courtney pulled down the lever and the mud monster was shrinking down, turning into dust.
"It's only dust." Kala said.
"This is all starting to make sense now." Paulina stated.
"It is?" Zan asked her.
"Yeah, think about it," Shadow Wolf replied before going to the computer and typed on it before she pressed a button and showed a picture of the villain she had in mind. "There's only one villain who could be responsible for this; watch this."
"No way!" Arceus replied.
"I don't believe it." Trent added.
"Believe it," Velma replied. "We've got to warn Batman!"
Shadow Wolf pushed a button to contact her godfather. "Batman? You there?" She then tried to call out.
The Crimson Cloak came on the screen before covering it.
"He's been captured," Kala frowned. "We have to help!"
"How?" Shaggy replied. "We're wanted by every police officer, villain, and superhero in Gotham."
"Hmm..." Fred hummed in thought.
"What is it, Fred?" Jayna asked.
"Plan B and the B is for Bat." Fred told the others as he took a look at the costumes.
"Groovy." Daphne replied.
"I call the Batwoman outfit!" Courtney called out. "Uh, unless you want it, Jayna?"
"You can wear it; I have my own costume." Jayna told her.
"I'm glad you see it my way." Courtney replied innocently.
Jayna rolled her eyes while shaking her head before looking around. "Come on, Zan, it's Wonder Twins time." She then called out to her twin brother.
"That's right." Zan replied.
"Wonder Twins' powers activate!" Jayna and Zan proclaimed in unison before they changed from their civilian outfits into their superhero uniforms.
"Magic Winx!" Paulina called out and she soon changed into her Winx form.
Fred, Daphne, Velma, Shaggy, Scooby, Trent, and Courtney grabbed the Bat Family's outfits while Brianna pulled out her mother's costume which was a black bodysuit with white stripe down the middle, purple gloves, purple boots, a utility belt with different weapons, including a crossbow, a black and white cape, and a purple mask. Trent blushed to Brianna's outfit.
"This doesn't make my butt look big, does it?" Brianna asked as she checked herself out.
Trent soon babbled and suddenly fainted.
"Uh, Trent?" Brianna called.
"Great..." Shadow Wolf deadpanned. "Elvis is a fainter."
Paulina snapped her fingers as a bucket of water splashed on Trent's face.
"Huh?" Trent asked. "What happened."
"You fainted." Paulina replied.
"Heh, sorry, guys," Trent smiled sheepishly. "It's just that Brianna looked kinda hot in that costume."
Everyone slightly rolled their eyes and got ready. Fred wore Batman's first uniform, Daphne wore the Batgirl outfit, Velma wore the Robin outfit, Courtney wore the Batwoman outfit, Brianna wore the Huntress outfit, Trent wore the Red Hood outfit, Shaggy wore the Nightwing outfit, and Scooby wore Ace the Bat Hound's outfit.
"All right, guys, let's go, but I'm leading." Shadow Wolf told the others.
"Sure," Fred replied. "No objections."
"That's what I like to hear." Shadow Wolf crossed her arms in satisfaction.
"Wouldn't be the first time Aquaman was saved by amateur heroes," Arceus commented. "I heard that he and Wonder Woman were being held hostage by the Legion of Doom once and they were saved by the Powerpuff Girls."
"Yeah, I remember that," Jayna replied. "Wonder Woman told us and the other Super Friends all about that."
"It was kinda funny to hear about." Zan chuckled.
"What are we waiting for?" Shadow Wolf replied. "Let's go!"
"We're coming!" The others agreed.
Everyone then went out of the Bat Cave to rescue The Dark Knight.
