A little while later, the cowardly duo showed up and they dressed differently, Scooby had on an orange sweater while Shaggy dressed like Fred, only in his usual and preferred green and brown over the blue, orange, and white.

"Right, like, it's time to solve the mystery," Shaggy entered with his best pal. "Let's kick this investigation up to an eleven!"

"What the heck are you two wearing?" Mo asked.

"Well, we figured the first step in solving a mystery would be to wear the right attire." Shaggy replied casually.

Cherry face-palmed and shook her head. "I'm surrounded by morons..." she mumbled.

"I'm sorry, Daph, but your go-go boots didn't fit... Me." Shaggy then said.

Scooby showed his back hind legs to show he had on Daphne's purple boots.

"Scooby!" Daphne scolded. "Those so don't go with that sweater!"

"I don't think any of those clothes go great together." Patch said.

Velma's machine was beeping and scanning.

"It found something!" Cherry rushed over and took the paper that was scanned.

"Ah, clues!" Shaggy said as he took the paper from her to observe it. "Alas, what are these strange markings?"

Fred turned the paper the other way since it was upside down. "Words."

"That moment when Fred's the smart one..." Cherry mumbled with an aside glance.

"Let's take a look at what we've found." Patch said.

"Scooby-Doo, take notes." Shaggy told the Great Dane.

"Rotcha." Scooby replied, taking out a pad and pencil.

"Gimme that!" Cherry glared, swiping the paper back so Velma could take a look at the reading.

"Please don't be real, please don't be real." Patch prayed.

"It's come back positive..." Velma whispered, confirming it. "This is a real pterodactyl scale."

"Precisely!" Shaggy chimed in, though looked fearful of that.

"That can't be possible!" Cherry grabbed her hair. "Who could make a real pterodactyl ghost?"

Daphne went over to the crime computer since Cherry did not have her laptop on her for once and looked up the origin of the real pterodactyl ghost for all of them.

"Wait... Dr. Jacobo: The Original Pterodactyl Ghost." Atticus said.

"That's right!" Velma remembered.

"Who was he?" Patch asked.

"Jacobo wreaked havoc in a statewide crime spree." Velma started to explain.

"Ohh, right, wasn't he a crazy scientist trying to create real monsters?" Patch asked.

"Exactly." Atticus said.

"Jacobo stole millions," Velma continued. "Which he used to finance his failed experiments trying to create monsters."

"You guys think Jacobo's behind this?" Fred asked.

"No way, one day he tried to escape prison and where it didn't end so well." Atticus said.

"What happened again?" Patch asked.

"His body was lost at sea," Velma explained.

"Well, how 'bout this?" Daphne stepped in. "Jacobo's cellmate was released from prison two months ago."

"Wasn't he Old Man Wickles?" Cherry asked.

"He was also The Black Knight Ghost." Atticus said.

"That was one of the costumes that was stolen." Fred remarked.

"Right!" Shaggy chimed in again. "And... Uh... Scooby-Doo, what's your conclusion?" he then asked.

"Runny." Scooby turned his notepad to show he drew a bunny and made the pad hop around.

"Wow..." Mo droned.

"I say we go to Old Man Wickles's place, and ask him a few questions," Atticus said. "In case if he's home."

"Come on then, let's go." Fred agreed.


With that, they all came to the Mystery Machine, Fred drove of course and everyone else rode in the back.

"You guys got room back there?" Fred asked their extra passengers for the day as Cherry texted her parents where she was going to be.

"Yeah, we got room." Atticus said.

"We're good." Mo added.

"All right, just hang tight." Fred said as he drove to Old Man Wickles's house.

They kept driving and Daphne gave her boyfriend directions since she knew where to go and Fred actually agreed with her and followed where she said to go.

"Hey, uh, Scooby, would you mind if you sit over here?" Patch asked, referring to sitting with him and the kids.

"Uh... Rokay..." Scooby agreed as he then went to the back to join the kids before Patch pushed Shaggy slightly to Velma.

Mo saw what was going on and smirked. Shaggy and Velma both blinked and then glanced to each other.

"Uh, hi..." Velma smiled halfway.

"Heh... Like... Hello..." Shaggy smiled back slightly nervously.

'Yep, they have feelings for each other.' Atticus thought to himself.

Nothing else was said between Shaggy and Velma, but at least they were getting 'cozy'.

"Freddy, up on right." Daphne said once they were at the front gate.

"Jeez, can't these two try to talk?" Patch whispered to his owner, referring to Velma and Shaggy.

"Probably don't know what to say yet." Atticus whispered back with a shrug.

"Old Man Wickles' ancestral manor." Cherry sounded slightly excited.

"Oh, man, another creepy crib," Shaggy muttered as bats squeaked. "How come we can't ever investigate, like, a Burger King or something?"

"Oh, come on; I bet it's not so bad in there." Atticus assured him.

"I wanna check it out..." Cherry sounded perky this time.

"Is this like, what you mean when you call yourself a 'perky goth'?" Shaggy asked, noticing Cherry being suddenly perky.

"You are correct, sir." Cherry smirked sincerely.

"Come on, it's not that very scary." Patch said.

"Then why does Cherry like it?" Shaggy asked.

"Raggy!" Scooby called, then did fighting moves before getting out with the kids and one puppy.

"Then again, 'Creepy' is my middle name." Shaggy smiled innocently.

"It is?" Mo asked.

"Yeah, why not?" Shaggy shrugged then as they all got out of the Mystery Machine to investigate.

"Um, okay?" Mo shrugged.

"Come on, Scoob!" Shaggy called for his canine best friend.

"Rokay!" Scooby joined him as they all left the van and stood in front of the ancestral manor.

They all climbed the stairs and passed a 'No Trespassing' sign.

"Looks a bit fixer-upper..." Cherry shrugged.

A couple of boys rode by on their bikes and got the groups' attention.

"Hey, nice job last night!" a boy called before putting his thumb down to diss them. "LOSERS!"

Patch began growling at the two boys.

"What dorks." the other boy said.

"Quick, we need to think of a comeback," Daphne whispered to her friends, then called to the bullying boys. "Hey! Shut up!"

"Yes, that's masterful..." Velma deadpanned.

Cherry's eyes seemed to flash from rage of the bullying boys and her body seemed to glow which released a white tiger with purple stripes to pounce out and then jumped right in front of the mean boys who then screamed at the sight. And rode their bicycles away from them as fast as they could. The tiger snarled viciously, but let them ride off and then the tiger wandered off, nuzzling against Cherry.

"Did you torment those bullies, huh?" Cherry cooed in a baby voice. "Did ya? Did ya scare away those meany butts?"

"I sure did." The tiger purred.

"Uh, like, you all see that tiger, right?" Shaggy pointed nervously.

"Go home now." Cherry told her tiger.

"As you wish..." the tiger nodded before disappearing back into Cherry's imagination.

"It's a long story." Atticus told the others. "We'll discuss that later."

Fred tried to let them in by ringing the doorbell, but an announcement was heard.

'You are trespassing on Wickles Manor,' a man over the megaphone announced as home security. 'Leave now or pay the price.'

Atticus was about to ring the doorbell next.

"Dude," Shaggy tried to stop him. "He just said we'd pay the price!"

"Oh, come on, Shaggy, what could possibly happen with ringing a doorbell?" Atticus asked before ringing the doorbell again.

Cherry face-palmed, knowing something would happen then since Atticus said that. After the doorbell was rung again, a trap door opened up and it made all of them fall instantly down through it.


They were all sliding down a chute and placed into a sphere which rolled them down roller-coaster like tracks and brought them all into a different room.

"That's what could happen by ringing a doorbell, Atticus!" Shaggy scolded. "That!"

"That was fun!" Patch cheered. "Let's go again!"

"Guh, let's not!" Cherry groaned. "I think I just dislocated my stomach..."

'At 7:00 PM, the owner will be home to set you free.' the man over the speaker told the new 'guests'.

"Hey," a little girl scout was shown to be in her own sphere and took out a box to show them. "You wanna buy a box of cookies?"

"Excuse me," a priest added as he took out a book and was standing beside a colleague. "Have you heard the Good News?"

"Reah!" Scooby beamed. "Rhere's rookies!"

"Let me see if I can get us out of these cage spheres." Atticus said.

Velma stood up. "Uh, thanks, Atticus, but there's a thumbprint scanner."

"Let me get my make-up." Daphne said, having an idea.

"Daphne, I know you're a girly girl, but I hardly think this is the time to check your make-up..." Mo sighed.

"You know what, Mo?" Daphne smirked slightly. "It's never too late to learn how to properly apply make-up."

"Let me guess, you're going to use the make up on the thumbprint scanner to get us free, right?" Atticus asked.

"Yeah," Daphne said as she did as he predicted what he said she would do. "The last good thumbprint should still be there, so... A little blush... A pore strip... And... Voila!"

This allowed the sphere to come apart and free them instantly.

"Okay, being a girly girl has its perks, I guess..." Mo shrugged. "Wait 'til I tell my mother."

"I enjoy being a girl." Daphne smiled, then decided to do the same with the girl scout and the two pastors.

"Okay, now let's find a way out of here and to the living room." Patch said.

"Hopefully before 7:00..." Cherry added.


It was a long walk, but they finally made it to the top floor. The girl scout and pastors thanked Mystery Inc and friends for letting them out, the girl scout even let them have some cookies on the house as a reward.

"Let's see if I can try to get my mechanic's job back..." one of the pastors muttered as he left with them.

"Rhanks for the rookies!" Scooby smiled to the girl scout.

"You're welcome!" the girl scout beamed as she eagerly skipped out the door.

"Okay, from here we should split up and search for clues." Atticus said.

"Yeah, come on, Scoob," Shaggy agreed, already going with the Great Dane. "We'll go this way."

Scooby nodded and left with Shaggy instantly.

"You stole the thing I say!" Fred gawked at Atticus like he was gratefully offended.

"Aw, just go with Daphne, we all know how you like pairing off with her." Cherry scoffed.

"Yeah." Patch nodded.

Fred turned red slightly, unable to say anything after that.

"I'll go with you wherever you go." Mo said to Atticus.

"I'll go with Patch..." Cherry shrugged.

"I was thinking of going with Scooby and Shaggy just to keep an eye on them," Patch said. "You still wanna come?"

"Yeah, who knows what trouble those two could get in around a place like this?" Cherry looked at the place. "I feel like I should know this place... It makes me think of a place that my mother told me about that she went to when she was a little girl."

"Mo and I will go with Fred, Daphne, and Velma." Atticus said.

"Okay, that'll do." Cherry agreed.

"Let's go!" Patch called as he walked ahead.

Cherry then followed the puppy.

"He did it again!" Fred whined which made Daphne and Velma roll their eyes at him.


"So, Cherry, you know this place?" Patch asked before they caught up with Shaggy and Scooby.

"I feel like I should..." Cherry said. "My grandparents were busy most of the time after they adopted my mother and her sister was getting married by the time she was born, so they had to send my mother to friends or family members... I think this is one of them."

"Cool." Patch smiled.

"It seems to match her descriptions and I have a photographic memory," Cherry said. "It inspired my gothic writing..."

"Ooh, there they are!" Patch found Scooby and Shaggy.

"Hey, guys, wait up!" Cherry called to them.

"Like, are you two joining us to help us search for clues?" Shaggy asked.

"Yeah... Sure..." Cherry shrugged, putting her hands in her pockets as always.

"Stay close..." Shaggy said, taking out a magnifying glass as they were coming through one hallway.

"Okay." Patch said.

Shaggy then mysteriously walked around with the glass.

"And I thought Atticus was over the top..." Cherry mumbled under her breath.

Scooby creaked one door open and decided to check it out. "Rearching for clues~..." he sang to himself as he investigated.

"You go with Shaggy, I'll be with Scooby." Patch said.

"You dogs do need to stick together..." Cherry understood as she left with the cowardly human in Mystery Inc.

Patch nodded, then came to the Great Dane's side. "Hey, Scooby, let me help ya find some clues."

"Rokay." Scooby smiled to him.

"But it might not be easy." Patch said.

"Reah..." Scooby agreed. He then found a safe that said 'SECRET: DO NOT OPEN'. "Raha! A clue!"

"That seems like it would be a possible place to keep a secret inside." Patch said.

However, Scooby stood up on his hind legs and took the sunglasses that were above the safe.

"Or you could find a clue to make yourself look cool..." Patch face-pawed.


While Scooby did that, Atticus and Mo were with the rest of the gang. There were glowing green footprints that were visible on the floor.

"Shiny footprints." Daphne noticed, she seemed much sharper in her detective work lately.

"I'm impressed, Daphne," Atticus smiled to her. "You seem more focused on solving mysteries lately than just looking your best or getting kidnapped."

"Well, I've matured since the last time." Daphne said.

"Still impressive." Atticus approved.

"That glow..." Velma looked at the footprints. "It's similar to the ptereodactyl ghost."

"Let's follow these footprints and see where they lead." Mo said.

"Good idea." Daphne agreed.

The footprints began to lead them to more stairs.

"We're getting warm." Mo diagnosed.

"They lead to his library." Atticus said.

"Should have the answers to what we need to know." Mo assumed.

"I think you're right." Atticus agreed.

Scooby and Patch kept exploring, though Scooby was looking through random items and calling them clues while Patch just rolled his eyes at the Great Dane, but was looking for real clues.

"Come on, there's gotta be a real clue around here somewhere." Patch said to himself while looking around.

Scooby opened one drawer and saw a private diary. However, he found a pair of white boxers with red hearts on them and wore them on his head like a hat. "A clue!"

"Steve on Blue's Clues has more common sense than you do..." Patch grumbled, a little frustrated and impatient with Scooby's goofball antics. The young Dalmatian then saw the private diary and found it more of a possible clue then what Scooby found.

"Well, it looks like Wickles shares Jacobo's fascination with the supernatural." Velma observed once they came up into the library to do further investigating.

"Yep, sure looks like it." Mo said.

Atticus began to look through the shelves of all the books until he finally found the book they were looking for.

"You sure you wanna do that?" Fred asked, remembering the doorbell incident.

"Yes." Atticus nodded before removing the book from the shelf.

And where to their luck, nothing bad happened. The others flinched, but grew relieved when nothing bad happened.

"So, is it the book we're looking for?" Mo asked.

"What is it?" Daphne asked.

Velma took a closer look at the book. "It's an obsolete Celtic text used by secret societies in the mid-19th century."

Atticus cracked the book open and there was a list of handwritten names on the front page.

"Look!" Daphne pointed to the final name on the list. "The book belonged to J. Jacabo, the original pterodactyl ghost."

"Maybe he gave it to Wickles before he died." Fred suggested.

"Being his cell mate, it would make sense." Atticus said.


Shaggy and Cherry were still looking for clues.

"Hey, Cherry, check this out," Shaggy said once he found a dusty old gramophone. "It looks like a giant record player."

"That's a gramophone, genius..." Cherry mumbled. "You have to crank it and then the sound comes out through the top."

Shaggy did just that to see if it still worked. Nothing happened. Shaggy tried again and leaned in. However, there was an explosion and suddenly a rap song blared through the horn. Cherry scratched the needle and took out the record to wave away the dust and smoke.

"Man, like, that thing hasn't been used in years." Shaggy coughed.

"You said it..." Cherry grunted. "Gah!"


Back in the library, the book was placed on a table.

"Can you read it?" Mo asked Velma or Atticus once they found the writing after the book was opened.

"It's an amalgamation of magic and science." Velma noted.

"In English terms, it means?" Mo asked.

"The action, process, or combining of something," Atticus explained to his girlfriend. "This basically balances magic and science, the two greatest rivals in the known universes."

"Right." Velma nodded to that as she looked further. "Here's a list of ingredients on how to create your own carbon-based organic, composite predators."

Mo looked to Atticus again.

"It's an instruction manual on how to create monsters!" Atticus said in slight worry.

"Oh," Mo said before getting worried. "Ohh..."

"Yeah..." Atticus nodded once.

Fred, Daphne, and Velma looked very worried and scared then.


Meanwhile, back with Shaggy, Cherry, Scooby, and Patch...

"Scoob." Shaggy greeted his dog best friend once he saw him coming with the boxer shorts, sunglasses, and hat on, carrying a pile of useless junk.

"Clues!" Scooby said, dropping the stuff in the middle of the floor.

"Those aren't clues, Scoob," Shaggy sighed. "Those are just things you want!"

"Yeah, why would a toilet brush be a clue?" Cherry added once she saw the instrument in the pile.

"That's what I asked him when he grabbed it." Patch muffled, not getting any saliva over the diary he found.

"Scooby-Dooby-Doo~..." Scooby sang into the brush, acting like a blues singer. "Doo-Doo-Be-Dooby~..."

"Just 'cuz you can sing in it, Scoob, doesn't make it a clue..." Shaggy informed before laughing and singing with him. "It just makes it awesome!"

Cherry rolled her eyes, then bent down to Patch's height and took the book. "Whatcha got there, boy?"

"Wickles's diary," Patch replied. "I thought it'd be important."

"And you thought right, this could have some information that could be useful." Cherry smiled.

"Are you smiling?" Patch asked.

"Scoob, you got something on your paw..." Shaggy bent down and picked up a card. "'The Faux Ghost'?"

"It's a night club," Cherry explained as she looked collected Wickles's diary. "A lot of bad guys go there to hang out and talk about the heroes they despise."

"Wait, like, do you know what this means Cherry?" Shaggy asked.

Cherry paused a moment to think about it, then realized. "Patch, did you find this card?"

"No, I don't believe I have," Patch replied. "Atticus taught me how to read, I would've noticed that."

"Scooby, Shaggy, you guys found an actual clue!" Cherry told the cowardly duo.

This caused the four of them to celebrate. Shaggy and Scooby sang again and did a little dance together. However, the celebration wouldn't last long as Scooby accidentally ended up in a knight in armor's arms. There was deep, sinister chuckling that came with it. Scooby whimpered and screamed once he saw who he was with.

"Black Knight Ghost!" Shaggy pointed in fear and alarm.

"Let's see if this knight can stand a chance against a super-strong Dalmatian." Patch said before acting like a bull.

The Black Knight Ghost laughed. Scooby jumped out of his arms and the boxers fell off around him and ended up in the knight's face. Shaggy and Scooby only did what they did best: Run away like little girls.

"Hey, Knight! Let's see if you can handle a raging puppy with the strength of ten bulls." Patch glared.

The Black Knight Ghost glared down at Patch with glowing green eyes.


In the library, Fred, Daphne, Velma, Mo, and Atticus overheard the screaming and decided to get going right away. Patch began to charge right at The Black Knight Ghost like a bull. The Black Knight Ghost fell back slightly. Patch snarled viciously to him. Cherry decided to go after Shaggy and Scooby to help them. Patch then knocked The Black Knight Ghost into the wall before joining up with Cherry and the cowardly duo. Shaggy, Scooby, and Cherry were now running around, trying to block the door so the Black Knight Ghost couldn't get through and get them. Patch was able to get in before they started to block the door.

"Patch, thank goodness you're here, we heard you're as strong as Atticus," Shaggy said. "We got some heavy stuff here!"

"I'll handle those." Patch said as he went and lifted up a grandfather cuckoo clock.

"Good." Cherry said as she couldn't lift a whole lot.

Patch began to pile up all the heavy stuff in front of the door.

"Let's see him get through this!" Shaggy laughed as he did more handiwork with Scooby.

However, the Black Knight Ghost came through a different door and wielded his sword. Patch came over to grab another item until he saw The Black Knight Ghost and groaned should have known there would be a secret door.

"We outsmarted that moron!" Shaggy laughed.

Cherry glanced at the ghost. "Ooh, this is awkward..." she actually smiled, which was not a good sign.

"Reah!" Scooby grabbed a lampshade. "What a moron!"

"Guys, I think you should stop talking now." Patch said.

Shaggy took another object, unknowingly from the ghost. "Thanks!"

"You're welcome..." The Black Knight darkly replied.

Shaggy and Scooby then realized the Black Knight Ghost was with them which made them instantly scared.

"How did you know there was a secret door?" Patch asked the ghost.

"Never mind that, I would rather you all get 'cut up' in our discussion!" The Black Knight chuckled darkly as he brought out his sword.

Mo, Atticus, Fred, Daphne, and Velma rushed over and Fred held a shield.

"Yo, Metal Head!" Fred held up the shield. "Bring it!"

The Black Knight punched the sheild which also injured Fred

"He brought it..." Fred murmured before falling in the middle of the floor.

"I knew I should've held the shield..." Atticus groaned.

"Then why don't you take his place, knave?!" The Black Knight Ghost told him.

"Gladly..." Atticus smirked in determination.

"Atticus, hold him off!" Velma commanded.

Daphne checked to see if Fred was okay. Luckily for her, Fred was just unconscious.

"You got it, Velma." Atticus said as he picked up Fred's shield and got himself a sword.

"I'll look in the book," Velma said as she cracked the book open. "Maybe there's a formula for finding his weakness."

The Black Knight laughed as he challenged Atticus, but both weren't going down that easily, and where to The Black Knight Ghost's surprise, Atticus was a lot stronger than the ghost had thought he was. The ghost wasn't going to let him win though, he decided to taunt the boy with his advantages of being a ghost.

Atticus didn't let this get to him."Could really use that answer right about now, Velma."

"Here..." Velma found the instruction and tried to read it.

Daphne and Fred held each other as they tried to dodge with Velma and Atticus against the Black Knight Ghost.

"'To find the creature's weakest point, take the angle between the current position of the sun and your geographical point'..." Velma started to read as Atticus and the Black Knight were at it.

Atticus continued to fight off the ghost as he began to overpower the sword. "VELMA!"

"'Add this point 28 and a half feet up from sea level'..." Velma continued to read and maintain focus.

Atticus tried to stab the sword against the Black Knight.

The ghost just giggled in mild amusement. "That tickles!"

"This is bad." Daphne frowned.

"You got that right; I guess I should have known that he wouldn't have a stomach." Atticus said before pulling his sword back.

The Black Knight Ghost merely laughed in his face.

"I'm warning you, I got the same strength of a Greek god and the most powerful man in the universe." Atticus said sharply.

"Oh, really?" The Black Knight Ghost taunted. "Then try to overpower me by using your full strength!"

Atticus snarled. "You asked for this, Metal Head!"

The Black Knight Ghost laughed at his threats. "I always love a knave who thinks he can dare challenge superior like me!" But to his surprise, Atticus was able to overpower him in strength.

That still wasn't going to keep him down however.

"Give up!" Atticus demanded.

"Never!" the Black Knight Ghost laughed, despite being weaker in comparison, that still wouldn't stop him. "Maybe I should take your maiden as my own!"

This angered Atticus even more, overpowering the ghost, even more, not caring if he was being brutal to the ghost.

"'Take the square root of 30,869'..." Velma continued to read.

The Black Knight Ghost then made his sword fly and fight against Atticus's abilities. "Look, no hands!" he taunted the boy.

"Yeah, I don't care about that ghost." Atticus glared as he began to fight the floating sword.

"Any time would be great, Velma!" Daphne urged the smart girl to find the weakness, she knew Atticus was fine, but she was anxious for this ghost to be defeated.

"I'm trying!" Velma cried as she still read. "'Subtract one, divide by B, follow upward eight degrees north'...' she then realized what that meant and came in front of the ghost before kicking him right between his legs. "Which makes his greatest weak point right here!"

The Black Knight Ghost dropped his sword and grunted. "Right in the round tables..." he muttered in slight agony.

Atticus decided to kick the ghost in the same place only with full strength, sending The Black Knight Ghost into the ceiling. Fred crossed his legs slightly almost as if he felt that.

"RUN!" Velma told the others.


With that, they all decided to run out of the manor.

"Rin your race!" Scooby mocked the Black Knight Ghost as he ran with the others and shoved the lampshade on his head.

"Quickly, let's get back to your place." Mo said to the Mystery Inc gang.

They nodded in agreement to that as they made their great escape. Shaggy nearly shut the door before Scooby got out, but luckily, he did. Everybody returned to the meeting place and parked the Mystery Machine outside and they were officially back to work and business.
