"We've got to solve this mystery tonight, and I know just the person to help us do it," Velma told the others as she soon brought a radio out. "Professor Pembrooke? Come in, Professor... Do you read me?"
"She shouldn't be out in the loch alone," Shannon frowned. "Especially tonight."
"I hope nothing's happened to her." Daphne hoped.
"Maybe she's out looking for Nessie." Cherry said.
"She could be out of range or at the other end of the loch." Bud suggested logically.
There was soon a snarling heard.
"Please tell me that was someone's stomach." Cherry begged.
"Nope." Everyone else shook their heads.
"I was afraid of that." Cherry replied.
"Nessie, it's me, Atticus!" Atticus told the Loch Ness Monster.
The only thing he heard was random roars.
"Nessie?" Atticus frowned.
"DRIVE AROUND!" Cherry panicked as she flailed her arms.
"That's not Nessie!" Atticus told them.
"Are you sure?" Little Dipper asked him.
"Those roars were just gibberish." Atticus said.
"Hmm... Well, I suppose if anyone would know about that, it would be you." Little Dipper told Atticus.
"We have to lure it to some place that has water, but isn't so deep." Atticus said.
"But where?" Patch pondered in thought himself. "Hmm..."
"I know." Little Dipper smiled.
Everyone then looked to Little Dipper.
"Oh, what is it, Little Dipper?" Shannon asked the Dalmatian who seemed quite intelligent for his age.
Little Dipper soon whispered to her what he had in mind. Shannon listened with a smile while everyone else leaned over.
"I'm a clever clogs!" Little Dipper smiled, proud of himself.
"So, where do we go?" Velma asked.
"Leave this to us." Shannon replied as she took control with Little Dipper.
"This better be worth it." Cherry muttered with a roll of her eyes.
"It will." Little Dipper said.
They soon went off to where Little Dipper and Shannon had recommended, and it was a swamp.
"A swamp?" Hallie and Annie asked.
"Trust me, this is fool proof," Little Dipper promised. "And stop the van now."
The Mystery Machine soon came to a stop.
"I sure hope this goes well." Darla hoped to herself.
The top of the van seemed to fly off and land in the swamp due to the destruction it faced during this whole adventure.
"Well, that just happened." Cherry muttered.
"And here comes the fake Nessie." Domino said.
"This is the moment I've waited for my whole life!" Del grinned excitedly.
"Wait for it." Little Dipper said.
Nessie soon came out from the forest which made everybody scream into a panic.
Cherry screamed too until she narrowed her eyes. "Hey, Atticus was right, it's a fake!"
"Told ya." Atticus said.
"Man, it looks worse than the original Star Trek special effects." Cherry replied.
"Hey!" Bud pouted about that since he loved Star Trek.
"I think we need to take a closer look at this monster." Fred suggested once they all realized that this Nessie was a fake one and not the real Loch Ness Monster.
They soon took off the disguise of the fake Loch Ness Monster.
"That's Del's van!" Annie and Hallie told each other in unison.
"Aw, she's not real?" Del frowned in disappointment. "Aw... But... My van!"
"Crazy little man..." Bud rolled his eyes which made Michelle giggle to him.
They soon opened one of the doors to Del's van.
"This can only mean one thing." Little Dipper told the others.
"And what would that be, Little Dipper?" Scrappy asked.
"Nessie or not, there's still part of this mystery to be solved," Little Dipper replied before taking seaweed off of Del's van tire before muffling. "And someone's been using Del's van to make a fake Nessie to scare us all out of Scotland!" he then ate the seaweed before grunting. "Ugh! That tastes worse than spinach!"
"I agree." Cherry nodded.
"Aw, seaweed is actually delicious." Michelle smiled innocently which made Cherry gag and stick her tongue out in the background.
"There's only one thing left to do." Little Dipper continued.
"Take a two week vacation to a tropical paradise?" Shaggy asked.
The sheep next to him then let out a bleat which sounded a lot like 'Bahamas'.
"Yeah, like, The Bahamas!" Shaggy agreed.
"Where'd that sheep come from?" Hallie asked.
"Must've crashed on the way." Annie pondered.
Domino giggled as he fluffed up the sheep's wool as he loved how it felt.
"Besides, you chickens, we have to head back to Blake Castle," Little Dipper informed logically. "I got a plan."
"Are we really going to listen to a dog?" Cherry deadpanned.
"Yes, we are." Atticus said.
Cherry groaned as she felt like the only sane person left.
"This'll be crazier than the last Dragon Games in... A very long time..." Drell replied as it was such a long time ago. "Anyway, what's the plan, Little Dipper?"
"Follow my lead." Little Dipper told them before revealing his plan to all of them.
Everyone was now listening to his plan.
Later that night...
Darla carried her parasol as she was in a boat with Atticus and they were both in rain coats as he paddled her with Cherry while Shaggy, Scooby, and Scrappy took another boat after being bribed by Scooby Snax.
"I love it when those two are bribed." Cherry said.
"Atticus, can Yuki, Teresa, and Elena come to Comic Con with us if we go?" Darla asked her big brother.
"Um, I'm sure they can, Darla, but why?" Atticus smiled to his little sister.
"Yuki wants to see a comic book about some ducks..." Darla replied. "Uh... Powerful Ducks? Strong Ducks?"
"Mighty Ducks?" Cherry replied.
"That was it." Darla then nodded.
"Sure." Atticus said.
"Thanks, Atticus," Darla smiled. "It would mean so much to her."
"Any comics that Teresa and Elena want?" Atticus asked.
"Elena wants to see Aquaman comics and I think Teresa said something about Bumblebee from The East Titans." Darla paused to think it over.
"All right." Atticus said.
Scooby soon took out the box of Scooby Snax and began to eat them.
"Could I have some too, Uncle Scooby?" Scrappy smiled.
Scooby smiled back to his nephew and shared with him and Shaggy.
"Still tasty." Scrappy smiled.
Back at the castle...
"Shaggy, Scooby, Scrappy, Cherry, Atticus, and Darla are in position," Velma said through her walkie-talkie. "Is everyone else ready?"
"Sonar is up and running," Daphne replied as she was with Shannon, Little Dipper, Bud, Michelle, and Sir Ian. "Everything's clear at the Cove, we're standing by. Over."
"This is a genius plan, Little Dipper." Shannon smiled.
"Oh, thank you," Little Dipper smiled back sheepishly. "I try my best."
"Ye are a very smart little puppy." Shannon giggled as she ruffled up his fur.
"That tickles." Little Dipper smiled.
Shannon smiled back.
With Fred and the others...
"Isn't this fun, Annie?" Hallie smiled.
"Yeah, we get to make a trap!" Domino added.
"Oh, dear..." Annie replied shakily. "Maybe I should've stayed home with Mum, Dad, Grandfather, and Sammy while he barks to the poodle next door."
"You mean the one he has a crush on?" Domino asked.
"Is that why he barks to her?" Annie asked before giggling. "Well, that explains a lot."
"I don't see the fake Nessie yet." Hallie said.
"Neither do I..." Annie said as she looked around.
Fred soon spoke into the walkie-talkie to Velma which made Annie and Hallie groan slightly.
"Yeah... Um... Hi," Del said as he took the walkie-talkie. "It's Del, we're ready, Velma."
They soon saw fog coming in.
"Oh, uh, hang on," Del told Velma. "We got a problem! Fog's rolling in fast!"
"I can't see!" Cherry cried out as her glasses had fogged up. "I can't see!"
Atticus soon cleaned her glasses. Cherry waved the air in front of her face as she looked more blind than usual.
"It sure is foggy..." Darla pouted. "My hair is going to frizz..."
"Don't worry, it'll be fine." Patch said.
"Uh-oh," Velma frowned as she looked through her binoculars. "I've lost visual on Scooby, Shaggy, Scrappy, Cherry, Atticus, and Darla. Velma to Shaggy and Atticus, are you guys okay?"
"Negatory on that, Velma, like, we got a major problem down here," Shaggy replied. "We're all out of Scooby Snax!"
"We're fine." Scrappy said.
"It's going all right, but we can't see much over here." Darla told Velma as her curls seemed to be frizzing out and her hair was soon long and stringy like on a moppet doll.
"I hope that we'll find Nessie or the fake Nessie soon." Patch said.
"I hope so too," Darla pouted. "My hair looks stringy."
"Yeah, you look like my old Betty Spaghetti doll." Cherry teased.
"Not helping!" Darla yelped.
"Well, it's true." Cherry defended.
With the sonar tracking...
"Nessie is coming..." Little Dipper told the others. "Sir Ian! Come over here!" she then called out to the older Scottish man.
The older Scottish man soon came over.
"There it is again," Shannon told Sir Ian as she watched with Little Dipper and her American cousin. "It's headin' right into the Cove!"
"Good gravy!" Sir Ian gasped.
"Let's tell the gang." Little Dipper said.
"I'll call Velma." Daphne nodded as she was about to get the walkie-talkie until someone grabbed it from her.
"Let's not be hasty." McIntyre smirked.
"What are you doing?!" Little Dipper asked.
"McIntyre, what's going on?!" Sir Ian demanded as they were soon surrounded and grabbed a hold of. "What?! No, you can't do this! This is mutiny!"
"Forgive me, Sir Ian, but I've come up with a little plan of me own," McIntyre smirked to the old man. "I intend to capture that creature, and sell it for quite a handsome amount of cash."
"And how are you going to catch it?" Little Dipper asked.
"The old-fashioned way." McIntyre smirked darkly to the Dalmatian puppy.
"The old-fashioned way?" Little Dipper asked out of fright.
The other men soon went with McIntyre as they loaded up a harpoon.
"That's a harpoon!" Little Dipper gasped. "You can't go Captain Ahab on Nessie!"
"Ah, shut up, ye wee mutt." McIntyre scoffed.
"But if you shoot her with the harpoon, it'll hurt her!" Little Dipper told him.
McIntyre soon forced a muzzle on Little Dipper. Little Dipper muffled and glared at the revealed evil man.
"Leave me dog alone!" Shannon snapped.
"Aye, and what are ye going to do about it?" McIntyre smirked.
Shannon glared, but looked a little sad for the Loch Ness Monster.
Meanwhile...
"Like, I can't see a thing," Shaggy frowned. "This fog is so thick, you could cut it with a knife."
"Isn't there some kind of fog vision?" Cherry asked Atticus.
"You mean telescopic vision?" Atticus asked.
"Fog vision, telescopic vision, X-ray vision, whatever," Cherry replied. "Isn't there someway you can see through this fog?"
"Telescopic vision can do that." Atticus said.
"Would you mind then?" Cherry asked.
"All right... One sec..." Atticus replied before doing just that.
Darla took a look below the water. "That can't be Urchin," She then said. "He only comes when I blow my magic conch shell from Uncle Triton and Aunt Athena." She soon saw that it wasn't Urchin.
"I doubt Urchin would come in a bog." Cherry commented, even if she didn't know the young merboy that well.
Shaggy and Scooby soon decided to sit back-to-back to make sure none of them would be taken by the monster.
"Well, nothing out in the fog," Atticus told the others. "How's the water looking, Darla?"
"M-M-Monster..." Darla's face turned white as a sheet.
"Real or fake?" Atticus asked.
"I'm not sure..." Darla shivered as the boats were soon raised up with the Loch Ness Monster underneath them.
"Atticus..." Cherry smiled nervously.
"Yes?" Atticus replied.
"DO SOMETHING!" Cherry yelped out in a panic.
"I'll try talking to Nessie." Atticus said.
"Anything!" Cherry yelped.
"Jinkies!" Velma panicked before calling through her walkie-talkie. "The monster is in the Cove, repeat, the monster is in the Cove!"
"Tie up your end, guys!" Fred told Del, Annie, and Hallie. "I'm going across!"
"You got it." Hallie said.
Del soon tied his end with the redheaded twins.
"Hit it, Fred!" Domino told the leader of Mystery Inc.
Fred soon did his part.
"Nessie, if that's you, give me a sign!" Atticus told the monster.
There were soon random roars.
"Owch, the broccoli is on the roof?" Atticus asked out of confusion. "Oh, you are so not Nessie!"
"Well, then this means we have nothing to fear." Darla said.
"Good for you guys!" Cherry shivered nervously since she had a crippling fear of heights.
Atticus soon covered his best friend's eyes. Cherry whimpered slightly. Darla then hugged Atticus's leg as she squeezed her eyes shut with tears in her eyes.
"Hey, put us down!" Patch barked at the fake monster.
'Hello?' Velma called. 'Can any of you guys hear me?'
"It's Velma!" Scrappy noticed and took the walkie-talkie. "Velma, it's Scrappy!"
'Are you guys aware that you're right on top of it?' Velma asked.
"By 'it', do you mean the monster?" Scrappy replied.
'Yes!' Velma replied. 'Your boat is on top of the monster's head!'
"MY NOSE IS BLEEDING!" Cherry panicked from the high altitude.
"Velma, like, I think we found the monster." Shaggy nervously told the genius of Mystery Inc.
"What do we do now?" Darla asked.
'Hang on, guys, help is on the way!' Fred called out as he, Hallie, Annie, and Domino were soon coming on the speed boat.
The fake monster soon tilted its head back which made the boats slide down its back and back into the water like a ride in an amusement park.
"Whee!" Darla smiled.
"This is awesome!" Atticus laughed with her.
Cherry looked uncomfortable as she pressed a tissue against her nose with her eyes crossed. The boats soon crashed through the water and broke apart suddenly. Something soon caught them keeping them from landing in the water without their boats.
"Atticus?!" Cherry asked. "Are there mermaids in Scotland?"
"No." Atticus said before seeing that it was another Nessie.
"Is everyone alright?" Nessie asked.
"Nessie, it's you!" Atticus beamed.
"Aye, 'tis true." Nessie replied.
"I don't feel so good..." Cherry groaned as she felt like she had enough insanity for one night.
"Don't worry, lassie, I'm the real Nessie and not that fake one." Nessie assured her before taking them to shore.
"Oh, God..." Cherry muttered. "Why can't I have a normal life like everyone else?"
Fred, Annie, and Hallie soon came to the dock and put the rope secure to trap the fake Loch Ness Monster. Domino bit on the rope after it was knotted and pulled it back to secure the bond.
"Good boy." Annie smiled.
Domino smiled back to her. The fake Loch Ness Monster soon got trapped and it seemed to be going well for Mystery Inc until a certain ship was coming right behind them.
"Why do I have a bad feeling?" Darla asked.
"You're not gonna get seasick, are you?" Cherry deadpanned.
"No, it's not that," Darla replied. "I just have a sinking feeling... No pun intended."
"Look, it's Sir Ian's ship!" Patch said.
"Maybe I should go stop it." Atticus said, about to get out of the boat.
"I see something pointy on it." Darla said as she squinted her eyes.
"Hmm..." Atticus hummed in thought before taking off his rain coat and came into the water and went under it as a merboy to see what his little sister saw, and what he saw was shocking.
Annie and Hallie held onto each other as Del's van was suddenly pulled.
"Uncle Patch, he's got a harpoon!" Little Dipper muffled through his muzzle in a panic.
"That's bad." Patch said.
"They put a muzzle on your nephew." Cherry observed.
"I'll make them pay for that." Patch growled.
The dock soon broke off which made everyone fly in the air before going to land in the water as Fred grabbed the post and Domino was taken for a ride with him since his mouth was on the ropes.
"Well, this is bad." Domino muffled.
Del soon found himself driving through the water and looked over to see Fred and Domino being dragged along. "Hey, guys, need a lift?" He then asked.
"How far ya going?" Fred asked before he tried to aim himself close and jumped into the other man's van.
Domino began to try to get to the van.
"Domino!" Annie gasped.
"Oh, he can't get in," Hallie frowned. "One of has to go and get him."
The rope Domino was holding on to soon snapped.
"DOMINO!" The redheaded twins panicked.
Annie soon looked around before holding her breath and she dove into the lake to save Domino. Domino began to try to swim back to them.
"Domino!" Annie gasped as she reached the surface.
Domino whimpered as he couldn't swim.
"Oh, he can't swim!" Annie frowned before holding her breath and going back under the lake to save him, and where she soon successfully saved her and her twin sister's shared pet.
"Annie!" Domino coughed.
"It's okay, Domino, I'll save you." Annie promised as she swam to Del's van while hugging her Dalmatian. After swimming for a while, she got help from Nessie.
"Annie, are you okay?" Hallie asked her twin sister. "That was really brave of you."
"I did my best." Annie said as Hallie wrapped up their Dalmatian in her coat so that he would be warm and dry.
"And looks like Nessie helped you get here." Hallie said.
"Oh!" Annie replied. "Um, thank you, Nessie."
"Should ye lasses need anything, just call me," Nessie replied. "Ye both remind me of an old human friend of mine I haven't seen in decades."
"Uh, Nessie, you should dive back down because they have a harpoon on the ship." Domino suggested.
"A harpoon, eh?!" Nessie glared. "Why can't these humans ever leave me alone?!" She then went back under the water.
"Whew." Annie sighed out of relief.
The others were soon on shore as the fake Nessie snapped at them. Sir Ian's ship soon aimed the harpoon at the fake Loch Ness Monster.
"Target in range!" A man told McIntyre.
Little Dipper soon gave Shannon a nod as he knew what she was thinking. Daphne then joined in with them as she had the same thought before she stepped on the man holding her's foot. Shannon smirked as she then did the same before going to join her American cousin, and which caused the man to let go of them. McIntyre grunted and looked over to see what happened and Little Dipper soon jumped from his arms and ran with the Blake cousins.
"This way, Little Dipper!" Shannon told him.
"I'm coming!" Little Dipper muffled.
Daphne took the hook off from her purse and latched onto a rope. Shannon and Little Dipper got on her back and they soon all zip-lined down the rope.
"FIRE!" McIntyre demanded.
"Oh, no." Little Dipper gulped.
"Don't worry, we got this." Shannon told him.
The two women soon knocked over the man which turned the harpoon the other way which fired it toward Velma at the castle, and luckily, she had ducked down just in time.
"Whew." Little Dipper muffled.
Shannon soon took the muzzle off of the puppy.
Little Dipper adjusted his mouth and smiled in victory. "It's off!"
Sir Ian's ship was soon being tugged by force from the harpoon along with Del's van in the back as the fake Nessie got out of the way.
"ABANDON SHIP!" A man yelled out as they were going to crash.
They soon got off the ship. Sir Ian came with them, but only because he lost his balance. The ship soon crashed through the rocks before coming to a stop.
"The brakes!" Fred called out to Del.
"Quick, use the brakes!" Hallie added.
Del soon did that before they hit the boat, but luckily, not crashing. Fred took his hand and helped him up along with Annie, Hallie, and Domino.
"HEEELP!" Sir Ian cried out as he was drowning. "Throw me a line! I can't swim!"
"Don't worry!" Hallie told him. "Help is on the way!"
Daphne, Shannon, and Little Dipper soon took a look at this.
"We've got to do something!" Shannon cried out.
"One of those levers should be able to save him." Little Dipper suggested as he gestured to the control panel behind Daphne.
"Ye might be onto something." Shannon smiled.
Daphne looked at the levers and soon tried to pull on them which soon lowered the mechanical arm.
"That's it!" Little Dipper beamed as his tail wagged in excitement.
Sir Ian soon saw the fake Nessie.
"Hang on, Sir Ian, help is on the way!" Fred told the old Scottish man.
Domino soon kicked over an inflatable monster from the top of Del's van to give Sir Ian a flotation device.
"I don't believe me eyes!" Sir Ian cried out as he saw the fake Loch Ness Monster.
The real Loch Ness Monster soon came out which confused Sir Ian.
"Stay away, ye impostor!" Nessie glared at the fake Loch Ness Monster.
The fake Loch Ness Monster was soon caught on by the magnetic crane.
"Serves ye right, ye wannabe." Nessie scoffed to the fake monster.
Shaggy and Scooby were soon heard screaming.
"Uh-oh..." Domino said as he looked over to see why Shaggy and Scooby were screaming, and to see that they were being chased by another fake Loch Ness Monster.
"Atticus!" Darla called out for her big brother.
Atticus came out to the surface and looked around while wading in the water to see the monster chasing the cowardly duo. "Huh?" he then wondered. "Where'd that come from?"
"Guys, look out!" Velma warned them. "That's where we set the-"
Shaggy and Scooby soon fell into a trap.
"Trap..." Velma finished with a sigh.
"Oh, no!" Daphne panicked for Shaggy and Scooby.
"Uncle Scooby, Shaggy, are you guys okay?" Scrappy called down.
"We're fine." Shaggy called back.
The monster soon snarled down to them.
"Like, but then again..." Shaggy gulped.
Scrappy put his paws up to fight against the Loch Ness Monster with the help of his Puppy Power.
"I think that monster might need a little shove." Little Dipper said.
The monster in the mechanical arm soon pushed the other monster into the trap.
"That works." Little Dipper shrugged.
Shaggy and Scooby soon rushed out of the way as the monster crashed onto the ground. The cowardly duo soon ran out of the trap since the second fake monster was now in the trap.
"Guys?" Scrappy nervously asked as Velma came beside him.
"Terrific!" Shaggy told Scrappy. "Considering we're squashed under the Loch Ness Monster!"
"Ruh?" Scooby asked before looking with him and the two ran out due to their cowardice.
"I think you better take another look." Scrappy told them once he saw that the monster was fake.
Shaggy and Scooby soon took another look to see that the Great Dane puppy was right and saw two familiar brothers.
"Colin and Angus Haggart?" Shaggy asked out of shock.
"Rawr...?" Colin and Angus roared innocently.
"Wait, did I just hear those two jokers' names?" Atticus asked as he got to the surface.
"Oh, Atticus, thank goodness you're okay." Darla replied.
"Hey, kiddo," Atticus smiled as he gently ruffled up her now greasy hair. "I wasn't gone that long, was I?"
"Maybe as long as Patch was when he met Santa Paws for the first time." Darla muttered slightly.
"Yikes." Atticus said before changing back to his human form.
"Well, okay, you were gone forever!" Darla pouted. "I missed you..."
"I missed you too," Atticus replied. "Now then, let's go see the Haggart brothers."
"So, if that monster's a fake, then what about that one?" Scrappy asked while pointing to the monster held up by the mechanical arm.
"Also a fake." Nessie said.
The others gasped as they saw yet another Loch Ness Monster, only, this one was real.
"Guys, this is the real Nessie," Atticus told the others about the Loch Ness Monster with him. "Now, that one, I'm not sure is... Do you know, Nessie?"
"I just know it's a human tryin' to ruin me good name and ruin me privacy." Nessie muttered in misery.
The fake Nessie was soon released and to be shown who was inside.
"It's a robot!" Scrappy yelped.
"Don't be a dingus, Scrappy." Hallie chuckled to the Great Dane puppy.
The metal doors soon opened up to show who was the one in control all along.
"Professor Fiona Pembrooke?!" The others gasped in shock.
"You!" Nessie added.
"I knew it!" Bud exclaimed.
Everyone gave him an odd look as he obviously did not.
"I can't believe you, Ms. Pembrooke," Cherry said to the woman. "I started believing in the Loch Ness Monster, and you were ruining her good name!"
