They all met up at the fountain.

"Skip!" Brenda ran up to Skip and hugged him "You're okay! Oh I was so worried!"

"So how was your encounter with Flash, boys?" April asked the guys.

"Like, it's a long story." Shaggy said. "Let's just say that Mudsy and Boo saved the day when Flash's two enemies, Professor Zoom and Gorilla Grodd tried to brainwash us into giving up our hearts."

"Zowie" said Taffy "Mudsy saved the day?"

"Gee Mudsy," April smiled "I had no idea you could be so brave."

"Aw shucks" Mudsy smiled "I was just looking out for my friends."

"So how'd you Teen Angels do with Wonder Woman?" Augie asked Daphne.

"Same as Shaggy said, it was a long story." Daphne replied. "But long story short, we had a tangle with Cheetah and Jenny Zin."

"Zoinks" Shaggy remarked. "Like, let me guess, Daph, those two tried to steal your hearts and even tried to kill you girls."

"That's right, Shag." Daphne nodded.

"Now we need to figure out where to go next" said Augie "Where's the crystal ball?"

Captain Caveman took the ball out of his fur "Me got it. Captain Caveman calling wizard man. Come in wizard man."

Mr. Van Ghoul's image came up on the crystal ball's screen.

"You called?" Mr. Van Ghoul asked.

"We've saved the Flash and Wonder Woman, Mr. Van Ghoul" Scrappy explained "Now we need our next mission."

"The next targets Zin is sending his men after are; Aquaman and the Green Lantern." Vincent explained "You'd better hurry."

"We'll do what we did before, we'll split up into teams" Shaggy said "It'll make the rescues a bit faster."

"We call Aquaman!" Clamhead exclaimed.

"Yeah," said Biff "After all, undersea worlds are our speciality."

"Alright" Shaggy nodded. "Then the rest of us will rescue Green Lantern."

"No way Shaggy" said Dee-Dee "You, Daphne, Scooby and Scrappy are going with the Neptune's. Mudsy and his gang are coming with us."

"Why?" Scooby asked Dee Dee.

"You probably have forgotten this," said Dee Dee "But we're gonna be a family and we need to find out if this will work. So we need some family bonding time."

"Like, works with me." Shaggy said. "In the meantime, we probably should get going now."

"Just a second" Biff ran away "Let me get the Neptunemobile. We're gonna need it."

Good thing they were where they parked their respective sweet rides. In just a minute, Biff came back with the Neptunemobile.

"Come on gang" he said "Get in."

Scooby, Scrappy, Daphne and the rest of the Neptune's jumped into the Neptunemobile.

"Hey!" Jabberjaw tried to get in "Make some room."

"Forget it, fish head" Shelly put him on the roof "You're traveling outside."

"But Shelly, Jabber's not gonna survive" Bubbles told Shelly.

Shelly slapped her forehead "He's a sea creature you idiot."

"Oh, yeah." Bubbles realized. "He's a shark."

"Now let's get outta here!" Scrappy said "We're disappearing by the second!"

"Alright, everyone" Vincent said. "Hang on!"

With that remark, he teleported the Neptunemobile and Jabberjaw to Atlantis before teleporting the other group to Coast City.

Back at Dr. Zin's hideout, he was having a video conversation with the Batman villains.

"I don't care if you can't find anymore!" He snapped at Harley and Poison Ivy "Bring me more villains and Batman, Robin and Batgirl's hearts!"

Harley tried to talk "But sir-"

"Get those hearts Quinn!" He shouted "Unless you ladies want me to suck up yours instead!"

He ended the transmission. Just then, Jenny arrived in the lair.

"Jenny!" Zin turned around "You're back!"

"Yes I am, father." Jenny nodded. "I've got bad news."

"What is it?" He growled.

"I failed to kill Wonder Woman" Jenny confessed.

"WHAT?!" Dr. Zin roared. "How could this have happened, my dear Jenny?"

"It wasn't my fault!" Jenny shouted "Those stupid meddling kids did it!"

"Enough" Zin put his hand up "I have discovered something important while you were gone."

"What?" Jenny asked.

"There's this magical book that details the history of Boomerland." Zin said. "It may be very useful in helping me taking over the place."

"There is?" Jenny asked. "How are you going to get it? And where is it?"

"The book is in the hands of the warlock Vincent Van Ghoul at his castle." Zin replied.

"I see" Jenny said.

"And that's not the least of it" Zin continued "I have Intel from our spies that some of our escapees are at the castle this very minute as we speak!"

"Then, we should move in and capture those escapees and the warlock himself and grab the book!" Jenny suggested.

"Exactly." Her father sinisterly smiled.

"I will not fail you father!" Jenny saluted.

"Then get going!" Zin said sternly, and his daughter nodded before taking her leave.

"And don't worry" she said as she left "I will bring them back!"

Author's Note:

Wowsers! Looks like the antagonists are going to get the book before our heroes do! In fact, let's back to the woods and see what they're up to! Stay tuned!
