Back in Boomerang City, Charlie, Jessica and the kids had been thinking of who they could find as a new king.

"Who could the new king?" Jessica pondered.

"Jessica, there are only so many people in the Funtastic World." Flim Flam told her. "Anybody could be king."

"Why don't we think of someone?" asked Jessica "Maybe if we put our heads together we can find someone."

"Good idea Jessica" said Charlie "Does anyone have any idea on who could that be?"

"Don't worry." Flim Flam assured the others "We'll figure it out in time."

"Do you really think so?" asked Charlie.

"Not really." said Flim "But I hope we can."

Nancy sighed "Oh Flim Flam, you're so smart."

"Gee," Flim Flam nervously smiled "Thanks, Nancy."

"There's no time for love," said Charlie "We have to find a king before it's too late."

"But where do we start?" asked Cavey Jr.

"I think I know some people." said Jessica.

"Who?" Everyone asked.

"Huckleberry Hound" She answered "And Pixie, Dixie and Mr. Jinks."

"They sound pretty forgotten." said Flip "Why don't we split up and search for them?"

"I call going with Flim Flam." Nancy raised her hand.

"Really?" asked Flim-Flam.

"No we're all going together." said Jessica.

"That's a good idea Jessica." Charlie said "We can't risk being separated. We must stick together."

"Aww" Nancy looked disappointed "I just wanted to be alone with Flim Flam."

Charlie looked at the sky and noticed the sun was setting "Hmm. Looks like it's getting late children, we'd better get some sleep and continue our search in the morning."

"Excuse me," said someone from the distance "Can I help you, citizens?"

They turned around. Two people were lurking in the shadows. It was Batman's female counterpart, Bat Girl and his dog, Ace the Bat-Hound.

"So nice to see ya'll drop in." Batgirl put her hands on her hips.

"Hey!" said Blue Falcon "You're Batman's female counterpart, Batgirl!"

"Were you expecting Wonder Woman?" said Batgirl.

"And you must be Batman's dog, Ace-Hound the Bat Hound." Dynomutt told Ace "I am Dynomutt, Dog Wonder."

"I am not his dog." Ace growled "I am his partner!"

"Sorry." said Dynomutt "You look like a dog."

"Well, I'm not his dog." said Ace "And that's final."

"So," said Batgirl "You must be the infamous, Blue Falcon."

"Yes, I Am." said Blue Falcon

"And I'm Dynomutt!" said Dynomutt

3h agoBatgirl looked down at Scooby.

"Oh my god" She gasped "Scooby-Doo?"

"Uh, rello?" Scooby waved.

Batgirl started hugging Scooby and kissing his cheek so many times.

"Aw, you're so cute" Batgirl then saw Scrappy. "And who's this widdle pumpkin?"

"Hi." Scrappy waved to Batgirl "I'm Scrappy-Doo!"

"You're Scooby's...son?" asked Ace.

"No!" Scrappy folded his arms "I'm his nephew, Mr. Partner."

"Pardon me?" Ace snarled.

"Uh, nothing." Scrappy smiled, nervously.

"Rand that's Elmo." Scooby showed Elmo.

"Ruff" Elmo shook Ace's hand.

"Nice to meet you Elmo" Ace shook Elmo's hand.

"So, what brings you guys to Gotham City?" Batgirl asked Blue Falcon.

"Here's the thing," Blue Falcon explained "Dr. Zin is capturing famous characters and stealing their hearts and Batman and Robin are two of the many characters they're trying to steal from."

"Word on the street is that the Joker and his allies, Harley Quinn, the Penguin and Poison Ivy have captured them." Batgirl explained "Ace and I are trying to find them."

"We'll help you find them" Dynomutt smiled.

"But how are we gonna do that?" asked Blue Falcon "We don't know where that Joker's secret lair is!"

"Me and Ace know!" said Batgirl "We were on our way there, when we saw you guys."

"You do?" asked Blue Falcon "Where is it?"

"Just follow me!" She said "Come on, Ace!"

Batgirl took a gun out of her utility belt and shot a grappling hook onto the roof of a building. Ace jumped onto his rocket board and followed her.

"Come on guys!" Batgirl said "We don't have much time!"

Scooby, Scrappy, Blue Falcon, Dynomutt and Elmo used their jets to follow them.

Meanwhile, back at the Joker's lair, the Joker was watching our heroes on his monitor.

"Heh, heh" He cackled "You hear that boys? They're coming...but not leaving."

"Oh, Mr. J" Harley laughed "You are so funny."

"Shut up!" Joker shouted at Harley.

"You won't get away with this, Joker!" said Batman.

"Oh but I will." He snapped his fingers. "Harley! Activate the machine!"

"Anything for you pudding" Harley pressed a button on the Joker's control panel.

It was a giant nozzle and it was coming right towards the Dark Knight and the Boy Wonder.

"Holy anchovies!" Robin gasped "What is that thing?"

"The Robo-Sucker." the Joker sinisterly grinned.

"It's the very thing that'll steal your hearts." Poison Ivy sinisterly grinned. "And when we're through with that, you'll be no more."

"Now!" the Joker pressed a button on a remote.

The nozzle went right onto Batman's chest and sucked his heart right out.

"Ugh." He groaned.

"You're next, Boy Blunder!" the Joker pressed the button again.

Then, the nozzle placed itself right onto Robin's chest and sucked out his heart as well.

"HA HA HA HA HA!" The villains laughed manically.

Both of the hearts were trapped in a glass case.

"Whoo hoo" Harley cheered "We did it!"

She then wrapped her arms around the Joker.

"Pucker up baby!" Harley closed her eyes and puckered her lips for a kiss.

"Pucker this!" the Joker slapped Harley upside her head.

"So what do we with them now, boss?" asked Poison Ivy.

"This." the Penguin pulled a lever on the control panel.

The floor hatch opened up and a huge vat of thinner came underneath the trapped Batman and Robin.

"Holy triple vison, Batman!" gasped Robin "We're in a real pickle this time!"

"I couldn't have said it better, Boy Wonder." Batman gulped.

Author's Note:

Ruh roh! Batman and Robin are about to be dissolved in the vat of thinner and their hearts have been stolen by the Joker and his cronies. Will Scooby and the rest of our protagonists make it there in time? Stay tuned!
