Scooby, Scrappy, Flim Flam, Daphne, Shaggy, Captain Caveman sr. and Jr, the Teen Angels,

"Jeepers!" said Daphne "Where in the multiverse do you guys think we are?" said Daphne

"Like, I don't know, Daphne." said Shaggy "But wherever it is, it looks like New York."

They were in a city. Shaggy saw a sign and read it. It said "WELCOME TO BIG CITY"

"I know where we are!" said Shaggy "Big City, Home of our old friends, Blue Falcon and Dynomutt!"

"Rynomutt?" asked Scooby "Rippie!"

Suddenly they heard in noise by a parked car, and saw a man breaking into it.

"Hey, buddy!" Daphne pointed to the man "What do you think you're doing?"

"Yeah" said Flim Flam "That ain't your car!"

The man turned and faced them. He had an orange beard and purple clothes.

"Who dares confronts Mr. Hyde?" he roared.

"Zoinks, its Mr. Hyde!" exclaimed Shaggy "One of Blue Flacon and Dynomutt's enemies! I recognize that costume from the time we went to that comic book convention."

"Heavens to Gary Owens." gasped Mudsy "He's s-s-scarier in person."

"Hideous Hyde Hound" Mr. Hyde ordered his dog.

The Hideous Hyde Hound growled and charged right at the gang.

"Alright you large mutt" Scrappy raised his fist "You're dealin with Scrappy Dappy Doo! My Uncle Scooby and I will rock you! Sock you! Right, Uncle Scooby?"

Scrappy picked up Scooby, who shivered. Augie and Skip screamed and jumped into each other's arms.

"E-E-Elmo, sick him boy!" Augie told his dog.

Elmo jumped into Captain Caveman's fur and started whimpering.

"Wussy" Augie called out to his dog.

"Hey!" Scooby and Scrappy said to Augie "You can't call your dog a wussy!"

"And besides," Skip added "You're the one who screamed out of his wits, so don't yell at Elmo."

"Will you boys stop fighting!" shouted April "In case you didn't know, we're gonna be attacked by a scary mutt!"

"Yeah!" said Taffy "Are y'all gonna get him or just be chickens and hide?"

"I don't need to answer that!" Brenda dived into Captain Caveman's fur.

"Make room for the Funky Phantom, Brenda Chance!" Mudsy flew into Captain Caveman's fur.

"Hey!" said Captain Caveman "Get out of there."

Captain Caveman shook everyone inside of his fur out of his fur.

The Hyde Hound leapt right up into the air, about to attack our heroes.

"AAAAAHHHH" They screamed.

"Looks like it's time for the Funky Phantom to vanish outta here." Mudsy turned invisible.

"Meow" Boo turned invisible as well.

"Come on you want a piece of me you freak?!" Scrappy threw his fists at the hound. "Why I'll splat ya! Come on Uncle Scooby!"

"Ro ray" Scooby jumped into Shaggy's arms.

"Get him Cavey!" Brenda shook and shivered.

"Stop him daddy!" Cavey Jr told his father.

Captain Caveman jumped into Taffy's arms and shivered with fear.

"Too strong even for me" He said.

"Run!" said Shaggy

Suddenly the hideous hyde hound was punched in the face by an arm, a boxing glove on a spring to be exact.

"What the?" Mudsy turned visible again.

"Jeepers" said Daphne "Didn't see that coming."

"What the heck just happened?" asked Flim Flam.

"Unga, did not see that coming." said Captain Caveman.

"We the heck just happened!" said a voice.

Everyone looked up and it was none other than…

"Blue Falcon!" said Shaggy.

"Rand Rynorutt!" said Scooby.

"That's us!" Dynomutt said proudly. "Hey BF! Look over there!"

"It's our old friends, Scooby-Doo, Shaggy Rogers and Daphne Blake!" said Blue Falcon.

"Come on BF!" said Dynomutt "Let's get down there and give them a big old greeting."

Dynomutt used his leg springs to jump to the gang.

"Right behind you dog wonders!" Blue Falcon followed him.

"Great to see you guys again." said Dynomutt.

"Rikerise" Scooby said to the robot dog.

"Put her there pal" Dynomutt held out his front paw.

They both did their secret handshake…which really ain't much of a secret.

"So you're the famous Blue Falcon?" Augie asked BF.

"Why yes, I am" said Blue Falcon.

"We helped them fight some bad guys a bunch of times." Daphne explained.

"That's my mom!" said Flim Flam.

"Anyways, what are you fellers doin here?" asked Dynomutt.

"Hey!" said BF "It's Scrappy-Doo!"

"We're here to get some help!" said Scrappy.

"Help?" asked Dynomutt "What kind of help? What's goin on?"

"My heart's coming back and I'm going to be popular again." Scrappy explained.

"However Scrappy can't be king anymore and we have only a short amount time to find a new king." Daphne explained.

"Or all the forgotten toons will disappear forever!" Flim-Flam continued "Including you guys."

"Oh my!" gasped Blue Falcon.

"That doesn't sound good!" said Dynomutt.

"And worse Dr. Zin is kidnapping popular toons and stealing so he can survive." said Scooby.

"Dr. Zin?" BF and Dynomutt gasped.

"Hey, could he use some help?" Mr. Hyde pondered.

"Only person you're gonna be helpin, is yourself to some prison food!" Dynomutt shot a net right out his chest which captured Hyde.

"So, will you help us?" asked Cavey Jr.

"Yeah" Captain Caveman added "Me always wanted to work with evolved superhero."

"Sure!" said Blue Falcon and Dynomutt.

"Boy, this team keeps growin and growin" said Dee Dee.

"We'd better hurry." said Daphne "The other popular characters could be in mortal danger."

"But first, we have to drop this slime-ball over to the prison!" Dynomutt reminded them.

Dynomutt flew over to the police station with Mr. Hyde in the net.

"Wait." said Blue Falcon "Where are Fred Jones and Velma Dinkley?"

"They're back in Boomerang Land with other teams trying to find Zin." Dee-Dee explained "As for us, we are going to save the still popular characters from Zin's agents."

"And we need you to help us!" said Brenda.

"Okay!" Dynomutt zoomed back from the police station.

"All right" Flim Flam cheered.

"However we'll need more superheroes to help us!" said Blue Falcon.

"Being a still popular character," said Daphne "My guess is that some of the still popular characters Zin's agents are going to go after are superheroes."

"Golly, even Dee Dee couldn't have said that better." Brenda pointed out.

Dee Dee folded her arms "I'm right here Brenda."

"So, how do we get back to wherever you were before?" asked Blue Falcon.

"How'd you get here anyways?" asked Dynomutt.

"With magic." said Scooby.

"Meaning?" Blue Falcon and Dynomutt asked at the same time.

"It was magic that brought us and it is magic that will get us back." said Shaggy.

"No seriously, how exactly are we gonna get back to the place you guys were before?" asked Blue Falcon.

"Yeah, are there magic shoes or a shuttle bus or something?" asked Dynomutt.

"Well," Augie reached into Captain Caveman's fur "We can use a magic button to get back home."

"A magic button" Dynomutt sniffed the button "How does it work?"

"We just press it and we're back in Boomerland." Skip took the button "Here, I'll show you."

Everyone gasped "No wait!"

Skip pressed the button and he was zapped back into Boomerland.

"Heavens to Betsy Ross" Mudsy gasped "Skip went off with the button!"

"This can only mean one thing..." said Scooby-Doo. "We're Scooby Dooby Doomed."

"I guess we're going to have to find another way to get back." said Taffy.

"But how are we gonna do that?" asked Shaggy.

"Say BF," said Flim Flam "Dont cha have a cave or something? Maybe we can use something that'll help us."

"I think so." said Blue Falcon "Come on. Let's go"

"We'd better be fast" Scrappy looked at his timer "We've got only 38 hours and 22 minutes."

They followed Dynomutt and Blue Falcon to their lair. Scooby and the gang hoped they could find a way to get back to Boomerang Land and save the world, in such limited time even.

Author's Note:

Well, looks like our heroes have run into the Blue Falcon and Dynomutt, Dog Wonder! However, Skip has accidentally sent himself back to Boomerang Land with the only method of getting there. Looks like our heroes will have to find a way to get back and save the other characters. In the meantime, what of Fred, Velma, Marcie, Madelyn and Googie? How are they going to locate Zin?
