Over the ocean, the Chan helicopter was fastly approaching the main continent.

"Here we are children" said Charlie "We're back home!"

"Hurry up and land this thing pop!" Flip exclaimed "This place is getting paler and paler!"

"Alright passengers" said Yogi "We are now descending into Boomerang City, capital of Boomerang Land's main continent."

"We all know you want to spend your last few minutes with your loved ones when you land, so thank you for flying Air Chan" Flim-Flam added.

The Chan Copter landed on to solid ground and converted back into a van.

"Thank goodness, we're back" said Pixie "Come on Mr. C, get us to that castle."

"Right" Charlie stepped on the gas pedal, but they started to slow down.

"Huh?" Jessica asked "What's going on?"

"The Chan Van is slowing down" Reddy said I think we're..."

Just then, the car stopped.

"Out of gas" Reddy said.

"I do believe we've just gotten the short end of the stick" Huck remarked.

"Why don't you go into the backseat Nancy and see if we've got a spare tank of gas?" Charlie asked his daughter.

"Sorry daddy" said Nancy "It's empty."

"We're in a real jam guys" said Jessica "And the nearest gas station is miles away."

"Looks like we're gonna have to get to the castle on foot" Flip said.

"G-g-guys" Ruff showed them his hand "I think I'm turning white."

"You're supposed to be white, Ruff" Reddy pointed out.

"Oh yeah" Ruff chuckled.

"Well, we'd better get going if we want to find the crowns soon." Charlie said.

"Yeah" said Flim Flam "But that's if we can get there fast."

"I'm getting weaker, guys" Nancy fell down to the ground "I can't go on any further."

"I'll carry you, Nancy." Flim Flam offered as he picked her up and started to carry her bridal-style.

"Gee, thanks, Flim Flam." Nancy smiled.

"No problem." Flim Flam smiled back as they set off for the castle.

"Boy," said Scooter "Nancy weighs a ton. I'm shocked that Flim can carry her. I'm surprised."

"Guys," Huck said "In case you don't make it, I'm gonna go home to my family. I want to spend my last few minutes with them."

Huck headed back to his house to spend some time final time with his family. He had to use whatever strength he had left to get him back to his wife and puppies.

"So long Huck" Yogi said.

"Don't worry" said Charlie "We will save the world."

Jessica took out her phone as she ran as fast she could "I'd better call Scrappy and warn him!"

Back on the Green Dragon, Scrappy heard his phone ringing and picked it up, unknowingly activating the speakerphone as he answered the phone.

"Hello?" He asked.

"Scrappy, we've arrived at the main continent." Jessica said. "But Houston, we've got a problem."

"What's the matter, Jessica?" Scrappy asked urgently.

"The Chan Van has run out of gas, and there's no gas station nearby, and we're miles away from the castle." Jessica replied.

"Uh oh" Scrappy said.

Before he could think of something to say, Shaggy, who managed to hear the conversation, said to the Green Dragon, "Like, master, maybe we should take a detour."

"Why?" The Green Dragon asked.

"Our friends have arrived with Scrappy's successors, but their car has run out of gas and we are miles away from the castle." Shaggy explained. "If they don't get to the castle soon, we'll all vanish for good. I was thinking if you can give them a lift."

"A lift" The Green Dragon asked. "Works with me so hang on, everybody"

With that remark, the Green Dragon sped up and flew by Messick Island in a matter of seconds.

Back at where Jessica was, she was confused when Scrappy said "Woah!" before disconnecting.

"Jessica, what seems to be the matter?" Charlie asked when he saw the confused look on Jessica's face.

"I was speaking with Scrappy, but then he was like 'Woah!' and then I lost the connection." Jessica replied.

"I hope he has figured out a way to help us." Yogi said. "Because we're really in a jam"

"My bro, Stanley couldn't have said it better" said Flip.

Just then, Mimi shouted, "Guys, look! Up in the sky"

As everyone looked up, they saw a green figure flying, and it seemed to be descending.

"Golly, I don't believe it!" Flim Flam said. "It looks like a dragon!"

Sure enough, a few moments later, the Green Dragon landed in front of them.

"Shaggy! Scooby! Daphne! King Scrappy!" Yogi exclaimed. "Mudsy! Boo! So happy to see you guys!"

"And look!" Scooter said. "A Green Dragon"

"Hop on board, everyone!" The Green Dragon said. "We don't have much time!"

Immediately, Charlie, Jessica, the kids and the animal characters hopped on board the Green Dragon, who then took off.

During the flight to the castle, Charlie said to the dragon, "Thank you very much, Mr. Dragon."

"You should thank Shogun Shaggy." The Green Dragon said. "He suggested that we should drop by and give you all a lift after explaining everything."

"Shogun?" the kids all looked at each other.

"That was some quick thinking, Shaggy." Daphne commented.

"Like, it was nothing, Daph." Shaggy smiled. "I'm just glad that we could help out."

"Reah" Scooby nodded.

Near the front, Scrappy was meeting with Ruff and Reddy.

"So you're Scrappy Doo, eh?" Ruff asked.

"Yeah" Scrappy smiled. "I'm Scrappy-Doo, and I'm happy to finally meet the two of you."

"And vice versa" Reddy responded.

"Oh boy" Ruff shook Scrappy's hand "So glad to know you! So glad to know you"

"Same here" Scrappy nodded. "I'm glad they found you guys when they did, because we're really losing our color now, with only 36 minutes left before we all vanish for good."

Soon, the Green Dragon arrived at the castle, and Charlie, Jessica, the kids and the animal characters got off.

"So where can we find the crowns, Scrappy?" Charlie asked as they got off.

"They're in the magical room near the top of the castle's main tower." Scrappy replied. "The door leading to the room has a crown on it, and it's hard to miss."

"Thanks for the information." Jessica smiled. "So where are you guys off to?"

"Messick Island" Scooby replied.

"Yeah" Mudsy nodded. "We've got to rescue our friends from that evil Dr. Zin and recover that magic book!"

"Well, wish you all luck." Charlie said as the Green Dragon started to ascend.

"Thank you." Scrappy smiled. "And good luck finding the crowns"

"We sure will need it." Jessica nodded.

After bidding their farewells, Shaggy turned to the Green Dragon and said, "Like, full speed ahead, master."

"You got it." The dragon nodded before speeding off.

Meanwhile, back on Messick Island, Vincent has finished explaining the function of the magic paintbrush.

"...and that's the story of the brush" he finished.

"Suffering succotash" Sylvester said "That brush may look like something from Junior's paint set, but it's probably a lethal weapon."

"So, anything we draw comes to life?" Bugs asked.

"That's right" Vincent said "And it also shoots thinner which can dissolve you as well."

"Now that's wicked" Hector added. "I wonder if I can use it to draw something for Christine."

"Boy," said Daffy "This is just like when the animator was messing with me that one time. I'll never live that down."

"Bet you won't." Bugs winked at the readers.

"So that means we can use it to defeat the villains and send them back to their worlds!" Jonny concluded.

"Precisely" said Vincent.

"But it won't be easy." Googie said. "We've still got those supervillains to deal with, and we're running out of time."

"Which also means that we better find the superheroes and free them" Fred said.

"Right" Vincent nodded. Using the magic paintbrush, he created an electronic map of the cell blocks of Messick Island.

"We'd better go save the superheroes if we are going to bring down these felons!" Googie said "In the meantime, Velma, Marcie you two get Hector back to his world! We'll free the superheroes!"

"Right." Velma and Marcie both nodded before leading Hector away.

"You know, I was considering that maybe we Tunes should stay and help." Bugs said. "After all, there's a large number of the likes of us."

"Good idea." Daffy said. "Time for those no-good baddies to get a taste of Duck Dodgers."

"I'm with you." Porky nodded.

"That's my Eager Young Space Cadet!" Daffy gave a thumbs up.

"Count me in." Sylvester said. "Nobody gets to eat this Tweety Bird but me!"

"Ohhh." Tweety remarked to the reader. "That putty tat is asking for more trouble."

"Meep meep." Road Runner nodded as Taz saluted in agreement.

"And I say, I say count us in." Foghorn said as he and Dawg shook hands.

"So will I!" said Speedy "Daffy and Sylvester, I know we've had our differences in the past, but this time, it is time for us to work together!"

"Awesome." Fred smiled before turning to Tom and Jerry. "Are you boys in?"

Tom and Jerry both stared at each other for a moment before nodding, with the former making a fist as if he was ready to punch some villains with Jerry sharing a determined look on his face.

"Way to go, guys!" Jonny smiled. "We've beaten Zin together before, and we can do it again."

"Then, let's get to work!" Googie said.

The heroes all nodded in agreement before racing off to find cell block 4.

Paying close attention to the map, the group noted that the superheroes were imprisoned in cell block 4. So, they had to find a way to free the superheroes without the guards noticing anything.

Author's Note:

Now, the Looney Tunes are going to have to work together to save the world! While the Looney Tunes are going to fight off some bad guys, Marcie and Velma are going to help Hector get home before his parents and sister find out! But inside of Hector, Ozzy, Drix and Maria are going to have to find a way to help Hector get home as well. They just need to think of something. And the rest of Fred's team will be freeing the DC superheroes!

As for Charlie Chan and his group, they have made it to the castle thanks to the help of Scooby-Doo, the Funky Phantom and the Green Dragon! But can they find the crowns in time (and in such a big castle)? It seems the more they fade, the weaker they get and they'll have to use whatever strength they got left to get to the top of the tallest tower. If they have any strength left, that is.
