A real pterodactyl ghost and Demonic Sunset on the loose/A big mystery in Adventure Bay

Here is how the mystery begins in Mystery Pups.

Suddenly out of nowhere, a big crack of lightning and thunder struck, all the lights in the museum went out.

Eddy: Hey! Who turned off the light?!

Then all of a sudden, another blast of lightning hit one of the museum windows. Glass shattered everywhere and started raining down on screaming patrons who all ran out of the way. Everyone started to panic as Mystery Inc. and some of the A.B.R.S. all met up in the middle of everything.

Blythe Baxter: What’s happening?

Jeanette then looked over toward one of the display cases covered by a curtain and noticed some strange green mist, walking slowly toward it, she gently reached out for the curtain and drew it back quickly. Big mistake that was when a ‘very’ real pterodactyl ghost and the Real Demonic Sunset Shimmer.

Demonic Sunset Shimmer: Remember me, Eddy!?

Jeanette: Oh, boy!

Demonic Sunset Shimmer: Surprise!

Then suddenly, the Pterodactyl Ghost and the Demonic Sunset Shimmer burst through the glass case and knocked Jeanette down.

Simon: Jeanette!

Peaches: Mommy!

The demon then took flight into the air inside the museum, Fred had to come up with a plan.

Fred Jones: We need to come up with a plan, these monsters are wrecking the museum!

Noah Sparkle: (hiding behind the Ryan F-Freeman costume) We're already on it!

Shaggy Rogers: (hiding with Noah) Hiding is our plan, it’s how we roll while meddling!

Scooby-Doo: Reah!

Noah Sparkle: In case you haven’t noticed, there’s an unidentified freaky raging she-gargoyle demonic object in here.

Soon, the Demonic Sunset flew around the room before grabbing the Black Knight costume in her claw as the Pterodactyl Ghost joined her with the 10,000 Volt Ghost costume.

Ryder: The curtains, (to Chase) Chase! I need you to your net to catch these monsters.

Blythe Baxter: And stop them from taking the costume, use the curtains!

Zoe Trent: Right!

Simon: On it!

Chase: Team Chase is on the case! (as he and his team ran over to grab the curtains) Come on, you chickens! Grab those ropes!

Scooby-Doo: Rokay, Chase!

Noah Sparkle: (grabbed the ropes) But chickens aren’t good with ropes! (as they got themselves tied up a bit) You see?!

Peaches: (scoft) Boys.

Jeanette: Can you believe it, Dot?

Dot Warner: Go fig.

Soon enough, the pups, pets and Mystery Inc. finally managed to get both the Demonic Sunset Shimmer and the Pterodactyl Ghost trapped in a corner and wrapped the curtains around it.

Velma Dinkley: Noah! Use the ropes to tie them up!

Noah Sparkle: (as he, Shaggy and Scooby started to circle around the two trapped monsters as they proceeded to tie them up) They're just costumes! They're just costumes! They're just costumes

Finally, they had the creature tied up and they held the ropes back smiling in triumph.

Shaggy Rogers: We tied them! Let go!

The gang and the two all let the tied-up monster go, only for the ropes to fall to the ground, completely untied. The curtains opened to reveal both the Demon Sunset Shimmer and the pterodactyl ghost grinning smugly with their arms crossed.

Demonic Sunset Shimmer: Is that the best you can do?

Noah Sparkle: Uh… Not necessarily?

Demonic Sunset Shimmer: Thought so.

Then, the Demonic Sunset Shimmer grabbed the Black Knight Ghost costumes and flew off into the air with the Pterodactyl Ghost who has the 10,000 Volt Ghost . Everyone noticed the ropes were still attached to it and were quickly pulled at an accelerated rate. Luckily for Shaggy and Scooby as they both were not tied, Noah looked down and noticed the ropes were still attached to him.

Noah Sparkle: Not good! (got flew up and started screaming as he crashed into Statler and Waldorf)

Statler and Waldorf (got hurt) HEY!

Noah Sparkle: You two had it coming for so long!

Fred Jones: We have to save Noah!

Ryder: As usual!

Blythe Baxter: Come on!

Just as the demon and the Pterodactyl Ghost flew him all around the room, the Demonic Sunset Shimmer forced Noah to crash into the buffet tables, pulling them right through a number of food dishes.

Noah Sparkle: (as the food went to him) Yum! (gasped) Flames! (grabs the bowl and rides on it) Whoo! Look at me! I'm riding the sunset! (laughing)

Evil Masked Figure: Mystery Incorporated!

Everyone turned toward the broken window where a menacing looking masked figure stood, dressed in black, he and Prince Achmed stood atop the damaged pane bellowing a deep, menacing chuckle as it looked down toward the team and the pups and pets.

Evil Masked Figure: This is only the first run on the ladder of Noah Sparkle's demise,

Meanwhile, the demon made Noah crash into the costume of Captain Hook and the sword it carried flew into the air. Yuki quickly ran forward and snagged the sword out of the air before it fell and chased after them as well as the demon got the Creeper, Jaguaro, Gator Ghoul and Old Iron Face costumes.

Prince Achmed: And this time, that pup that humiliated me is the one unmasked as a buffoon he truly is!

Yuki then cut the ropes with the swords, freeing Noah but causing them to crash against other displays, but allowed the Demonic Sunset Shimmer and the Pterodactyl Ghost to fly away with Achmed and the new villain out the broken window.

Cuddly: (calling out) Oh, yeah?! We’ll see who really is a buffoon then we can go “WHOO! I love the A.B.R.S.! They are the best!” But you, Prince Brat stink! You’re on the loser side of this cesspool!

Prince Achmed: (offscreen) Well, I never!

Alex the Lion: Never pick fights with puppies if you take my hint! (to Cuddly) So now what do we do?

Cuddly: I don’t really know, but we must do whatever it takes to stop those guys!

When the Demonic Sunset Shimmer and the Pterodactyl Ghost attack ended, the Adventure Bay Criminology Museum now lay in ruins with shards of broken glass and destroyed costumes everywhere. Most of the patrons already left in fear, while some had to be taken away to receive medical attention for injuries sustained during the attack. The only ones remaining in the museum were the police currently closing the area off as a crime scene, reporters covering the attack the A.B.R.S. while Noah was very ashamed of what he had done.

Noah Sparkle: (whimpering)

Ryder: (petting Noah) Oh, Noah. We're so sorry that you had been through a difficult night.

Blythe Baxter: But how did Prince Achmed get out of prison?

Beau Neville: I can answer that question.

Velma Dinkley: It’s Detective Beau Neville, the gang and I met him back at Moonscar Island before the zombie and werecat encounter.

Blythe Baxter: What brings you all the way from CN City?

Beau Neville: I’ve been working undercover to find any witnesses or suspects. I’d even had help from Del Chillman and his girlfriend Minga Sherpa.

Del Chillman: It’s true, we’ve been helping Beau during his live TV show of Beau Neville’s Detective Journeys.

Minga Sherpa: And we’ve been getting live footage of the real life pterodactyl ghost crashing the concert a few nights ago at Foggy Bottom with the Hex Girls.

Sweetie: (shocked) WHAT?! W-Why did he do that?

Beau Neville: We weren't certain how’d it happened, but we do know that Noah had nothing to do with that innocent on account of Mayor Goodway and Mayor Humdinger’s peace treaty.

Mayor Goodway: That’s true.

While they were all talking amongst themselves, Cuddly was still searching for possible clues. Examining the fake concrete slab the Pterodactyl Ghost stood on, she noticed it didn’t look melded into the stand as it was supposed to be. Reaching out and pulling it back, the slab lifted off the ground and opened up to reveal a secret tunnel hidden beneath it.

Cuddly: (gasped) Velma! Look what I found!

Velma Dinkley: What is that?

Cuddly: A secret hatch!

Teresa Whitehurst: Something tells me that the real Pterodactyl Ghost and that Demonic Sunset Shimmer must have come through here.

Just as Cuddly was examining the side of the hatch, her eyes widened as her mouth dropped upon noticing something glowing. Reaching over and picking it up, she stared in utter amazement at what resembled some sort of scale glowing a turquoise shade.

Velma Dinkley: Jinkies!

Cuddly: A reptilian scale, an actual pterodactyl ghost scale!

Teresa Whitehurst: A most wonderful clue!

Chase: But they stole six costumes.

Zoe Trent: The Black Knight Ghost, the 10,000 Volt ghost, the Creeper, Jaguaro, Gator Ghoul and Old Iron Face. Why?

Blythe Baxter: You know what that means, Ryder.

Ryder: Sure do, Blythe! We got a mystery in our hands.

Fred Jones: (overheard and laughs) Hey, Ryder, I was gonna say that.

Ryder: Oops! Sorry, Fred, didn't mean to steal your line.

Fred Jones: No offense taken, I get that sometimes. (to the Mystery Gang) But they're right, gang, it looks like we’ve got another mystery on our hands right here at Adventure Bay.

Daphne Blake: Jeepers! And it’s a big one with the pterodactyl ghost coming to life again.

Lilo Pelekai: But what about Noah? (picks up the whimpering Noah) He’s been feeling scared about getting hurt and being framed.

Velma Dinkley: She’s right, he’s feeling very ashamed and embarrassed when this whole mess happened.

Ryder: There's a problem I know that none of us can't handle, Valma. No mystery is too big, no pup, pet, hero or detective are too small! Even for our favorite pal Noah!

Blythe Baxter: Right you are, Ryder.

Perch Perkins: Fred, Daphne, could you and the others answer a few questions for the press?

Fred turned around, ready to answer any question, while Daphne and Blythe looked dead set against answering anything at this time.

Daphne Blake: Um, Fred, I don’t think that’s such a good idea.

Blythe Baxter: They usually address the press ‘when’ they unmasked the criminals. We looked ridiculous back there. Even Noah is still ashamed after what happened.

Fred Jones: Don’t worry about it, Blythe, the press loves you guys.

Then, the cameras started flashing as Fred and Daphne walked off to answer questions.

Teresa Whitehurst: Lilo? What if the police think Noah’s guilty for something he didn’t do? We can’t risk him being in jail.

Lilo Pelekai: I don’t know, Teresa. I sure hope things will work out well for him.

Beau Neville: Don’t worry, Lilo. I happen to know Noah’s innocence already, we’ll get proof soon enough.

Ryder: (to Peaches) Alright, Peaches, You know what to do.

Peaches: Right, Ryder! (twisting the dial) Calling all rescue teams, to the Mystery Mansion!

Cuddly and Min: Peaches needs us!

Pups and Pets: And Ryder and Blythe too!

Lucy Wilde-Gru: (carries Noah to the Mystery Mansion) Come on, Noah Let’s get going. (as Noah whimpers)

Pepper Clark: Come on, Marshall!

Marshall: Coming, Pepper! (slipping from the banana peel) Whoa!

Soon, Gru and the others brought the pups and pets to where the Mystery Mansion is located.

Felonius Gru: (noticing the mansion) Same paint job from the Mystery Machine, what’re the odds?

Dru Gru: Look at it this way, Gru, at least it isn’t too far from the Lookout.

Felonius Gru: Yes, that too.

Just as everyone’s about to enter the Mystery Mansion, they saw Marshall bump into Pepper while sliding down towards the group.

Chase and Mia: Look out!

Marshall: Whoa! (crashing into the other pups and pets) I would've gotten a perfect landing if it weren't for that meddling trip!

Pups and Pets: (laughing)

Just as everyone went inside the Mystery Mansion, they changed into their normal clothes as some had changed into their Mystery Inc. uniforms as the pups and pets went into their seats as Lucy put Noah who was dressed as Shaggy down.

Blythe Baxter: Everyone, welcome to the Mystery Mansion!

Shaggy Rogers: Zoinks! Like, you and Ryder sure worked up enough money with some merchandise you’ve been selling, Blythe!

Fred Jones: And some of the pups are dressed up to look just like us!

Ryder: That’s because it's a Mystery Pup emergency, Fred.

Daphne Blake: Wow, Ryder! How’d you come up with that?

Ryder: It just came to me, Daphne.

Skye: And I dressed just like you, Daphne!

Sweetie: And I dressed as Velma!

Noah Sparkle: (sadly) Zoinks.

Simon: Everyone has been accounted for, Blythe and Peaches, ma’am!

Chase: Mystery Pups and Mystery Pets ready for mystery action, Ryder, sir!

Ryder: Thanks for coming here so quickly, guys. The real pterodactyl ghost and the Demonic Sunset Shimmer had been stealing costumes and dummies.

Peaches: (in a Velma outfit too) And not only that, the evil masked figure and Prince Achmed are out to frame and humiliate Noah.

Pups and Pets: (gasped)

Skye: Poor Noah!

Noah Sparkle: (whimpers and hid his face while crying)

Ryder: (petting Noah) It’ll be okay, Noah, we’re here to clear your name.

Blythe Baxter: And we got a group of mystery solvers to help us crack the case.

Pups and Pets: (cheering) For Noah!

Skye: (to Noah) Don’t worry, Noah. We’ll help you clear your name and stop Prince Achmed and the evil masked figure somehow!

Ryder: So for this mission, it’s all hands and all paws on deck. (to Chase) Chase, you’ll be in charge of leading the A.B.R.S. to crack the case and prove Noah’s innocence.

Blythe Baxter: Zoe, Simon, you two back Chase up.

Zoe Trent: Right on it!

Simon: Anything for Noah!

Chase: Team Chase is on the case!

Ryder: And Tommy, this is where you come in with Tiger to find any clues.

Blythe Baxter: And once you two got enough evidence, report it to Chase and any Police Department on Noah’s side.

Tiger Wiggins: I’m ready!

Tommy: Let's solve this mystery!

Ryder: Everyone else, stand by until Chase gives the orders. Alright! Mystery Pups are on a roll!

Rita: Since Noah is so sad, I’ll say it for him. To the closet!

Zoboomafoo: They're going to the closet,

They're going on a trip.

They're going to the closet

To grab their stuff and split

Rita: (opens the closest saw it was organized and saw what she needs, picks it up and closed the door)

Runt: How did Rita do that? (opens the closet and everything fell on him)

Cuddly: Works only for girls.

Runt: Oh, yeah, that makes sense! Definitely makes sense.

Zoboomafoo: They're on a cool adventure

And they don't know what's in store.

They're coming from the closet

And they're heading out the door.

Dr. Nefario: Come on, Noah. Beau and Chief O’Hara are arranging for you to be on “What's My Crime?” to prove your innocence.

Noah Sparkle: (sadily) Okay, Dr. Nefario. (went with him) See you later, Skye.

Skye: Good luck, Noah!

Penny Ling: We’ll see you soon!

Just as all the teams’ deployment sequence is done, they went to the lab to help the mystery gang solve the mystery and help Noah prove his innocence.
