Meanwhile, Blue Falcon, Captain Caveman and the Teen Angels had been stuck in a jam. They didn't know where to find Superman.

"It's kinda dark" said Dee Dee "Cavey, do you think you can shed some light on us?"

"No problem" said Cavey.

Caveman took out his club and out came a bird holding a candle. That was enough to make some light.

"Now how on earth are we gonna find Superman?" asked Brenda.

"It will be like finding a needle in a haystack with a city this big." Taffy added.

Me know superheroes and usually we have a secret cave" said Captain Caveman "Perhaps he have cave."

"Wait a minute!" Dee Dee snapped her fingers "I got an idea!"

She reached into her skirt pocket and took out a folded "Superman" comic.

"A comic book?" Brenda put a hand on her hip "Dee Dee this is no time to be reading"

"And why were you carrying that?" asked Blue Falcon.

"I dunno" said Dee Dee "I guess I took it away from Jr. Point is, this comic could probably help us."

"Super terrific" said Taffy "Now we can get some info on Superman."

The Daily Planet" said Blue Falcon "That's where Superman works to cover his expenses. He disguises himself as a reporter."

"Then that's where we're headed" said Dee Dee "It might have clues on where we can locate Superman."

"Good idea, Dee Dee." said Brenda "Come on Teen Angels, to the Daily Planet."

"A building with a big planet on top shouldn't be hard to miss" Captain Caveman chuckled.

Meanwhile, Scooby, Scrappy, Mudsy and the others had followed the Dyno-Map's guidance to a suburban house.

"According to the map, Superdog lives in this house." April looked at the map.

"But everyone is probably asleep" said Skip "How do you think we're find out without waking anybody up?"

"Leave to me, Skip my boy" said Mudsy "It's Funky Phantom time! Come on Boo!"

"Meow" said Boo.

Mudsy and Boo flew up to the house and they flew right through it and made their way inside.

"It's great to have two ghosts around the house" April chuckled.

"Like, let's hope they don't spook the people living inside." Shaggy commented.

Just as Shaggy finished his remark, there was a scream coming from the house.

As everyone looked at him, Shaggy added, "Like, I just have to open my big mouth."

Inside the house, a little boy and a white dog were terrified. Luckily, the boy's parents and sister were sound sleepers.

"A g-g-ghost" the boy shivered "G-g-g-go away."

The dog barked something that sounded like "Don't make me use force."

"We come in peace." The Funky Phantom quickly said. "Don't be afraid."

"W-who are you?" asked the boy "And what do you want?"

"Oh pardon me," said Mudsy "Where are my manners? I'm Mudsy the Funky Phantom and this is Boo."

"Rrow" Boo waved his hand.

"So what're you doing here?" asked the boy "And what do you want?"

"We're looking for Superdog." said Mudsy "And we think you might have him here."

The white dog barked as if he was saying, "Oh, yeah? Well, you still haven't fully explain why you're here."

Before Mudsy could explain, the boy noticed several figures were outside the house.

"People!" the boy gasped "Outside our house!"

The dog walked over to the window and saw the people as well.

"I can't see from down here" the boy squinted his eyes "Who are those people and what're they doing here?"

"They're our friends" Mudsy explained "They'll explain everything."

"They'd better" said the boy "You guys almost scared the day lights out of me and Krypto."

Mudsy and Boo took Krypto and his master to the others. The boy was more than shocked.

"Oh my god!" the boy gasped "It's Scooby-Doo! And the rest of Mystery Inc! I can't believe it! I love you guys!"

"Zoinks! Scoob, it seems like we've got fans here in Metropolis!" Shaggy said quietly.

"Reah!" Scooby replied.

"Say, what's your name?" Scrappy asked the boy.

"My name is Kevin." The boy replied, "And this is my dog Krypto!"

"Krypto, as in Krypto the Superdog?" Dynomutt asked excitingly.

"Rye can't believe this" Scooby shouted "Ri'm talking to Krypto the Superdog!"

"Great to meet you as well Scooby-Doo!" Krypto reached out his paw.

"So what're you doing here?" asked Kevin.

"And why is there a tiny Scooby-Doo?" Krypto added.

"Like, this is Scooby's nephew Scrappy Doo." Shaggy quickly explained as Krypto shook paws with Scooby. "And he's the king of Boomerland, a land inhabited by forgotten cartoon characters like Mudsy and Boo, the two ghosts you've just met."

"So what brings you guys to Metropolis?" asked Kevin.

"Lex Luthor is gonna steal Superman's heart." Skip explained.

"His heart?" asked Kevin "What do you mean?"

Scrappy wasted no time explaining the function of the heart for each of the still popular cartoon characters and how the character disappears when the heart disappears.

"Well Krypto and I would be more than happy to help you guys find Superman." said Kevin "Right Krypto?"

"Right!" Krypto nodded. "But I can't do this alone. We'd better tell Streaky about this."

"Streaky the Supercat?" asked Daphne.

"Yes." said Krypto "Luckily, he lives right next door, so we can get him now."

With that, Krypto made his way to the house next door to get Streaky up, having to keep in mind that Andrea and her family were asleep.

"How are gonna wake them up without waking the rest of the Sussman's?" asked Kevin.

"Beats me." Krypto shrugged.

"Well we can't have Mudsy go in there" Augie pointed out "He could scare the patootie out of Andrea."

"I've got an idea!" Scrappy snapped his fingers "Why don't we have Boo go?"

"Oh, that sounds like a good idea!" Krypto replied. "He, in fact, looks quite like Streaky!"

"Heavens to Delaware" said Mudsy "He does?"

"You'll see when he comes out" Krypto winked.

"Okay Boo," Mudsy petted his cat "Go get this Streaky character and hurry!"

"Meow!" Boo flew right into Andrea's bedroom.

"Well I hope this time it goes well" said Augie.

Shaggy nodded without saying a word, not wanting to end up saying something that turns out to come true.

Boo made it into Andrea's room. He tapped on Andrea's shoulder.

"Streaky" she muttered in her sleep "Not now. Mommy's sleeping."

In spite of Andrea's comment, Boo continued to tap on her shoulder, trying to wake her up, but kept failing.

Boo cleared his throat "RRROWWW!"

Just then, Andrea woke up.

"Streaky!" She rubbed her eyes "It's late! You know mommy has to-"

"Meow" Boo waved to Andrea.

"Streaky, why are you white?" She asked him "And why are you wearing that hat?"

Just then, there was another meow coming from the room.

It was Streaky in his bed.

"I'm right over here Andrea" he said.

"What the?" She looked from left to right and saw both Streaky and Boo "Two Streakys?"

Before she could inquire, a small pebble was thrown towards her bedroom window.

"Now what's going on?" Andrea asked as she walked over to her window.

Looking outside, she spotted Kevin waving at her, and he was accompanied by Krypto and several other people.

"Kevin?" She asked "Is that you?"

"Hey Andrea!" Kevin shouted "Come down! We're gonna help save the world!"

"I'll see you downstairs" Andrea said "Come on Streaky!"

Andrea picked up Streaky and snuck downstairs to the backyard.

Boo simply floated through the wall and met them on the street.

"Okay, Kevin, care to update me on what's going on?" Andrea asked as she and Streaky arrived.

"And is why is there a white version of me with a feather hat?" Streaky asked.

"Like, we can explain all of this." Shaggy quickly replied just as Andrea recognized Scooby.

"Oh my goodness, you're Scooby-Doo and Mystery Inc.!" Andrea exclaimed. "Kevin and I both enjoyed watching your shows!"

"Looks like we've really got a lot of fans here in Metropolis." Daphne commented.

"Right." Shaggy nodded in agreement before adding, "Now, let's get down to business."

"You're Streaky, right?" Mudsy asked Streaky.

"Yes, I am, and you guys still haven't explain why there is a white version of me here." Streaky replied.

Immediately, the heroes quickly updated Streaky and Andrea on the going ons in Boomerland and Lex Luthor's threat to Superman and Krypto's need of Streaky's help.

"Oh my god" said Andrea "This is serious. I mean, we can't let Streaky. He's my little angel and there's no way I'm letting that Luthor creep, take my baby."

"Don't worry, Andrea." Krypto states. "I'll make sure that nothing terrible will happen to Streaky."

"Besides, we've got Boo here who looks alike." Shaggy added.

"Yeah! If you cover Streaky with white powder or dye, then Luthor won't be able to tell the difference between the two!" Scrappy added.

"Don't worry Andrea" Kevin out her hand on Andrea's shoulder "Streaky will be okay. He's a cat of steel."

"Yeah" said Scooby "A cat of steel."

"Okay" Andrea sighed "I guess so. Just promise he won't get into any trouble."

"I won't." Streaky told her.

"Now that's done, we'd better inform BF that we've found Krypto and Streaky." Skip said.

"Right there, Skip." Dynomutt said as he presses a button on the Dyno-Beeper before adding, "Dog Wonder calling BF."

Meanwhile, BF and the Teen Angles arrived at the headquarters of the Daily Planet just as Blue Falcon's beeper started making noises.

"Dog Wonder calling BF." The beeper said.

"Huh?" Captain Caveman asked. "What's that noise?"

"It's my Dyno-Beeper, Captain Caveman." BF replied. "Dog Wonder must have discovered something."

"That's right, BF." Dynomutt replied. "We've found Krypto the Superdog and Streaky the Supercat!"

"Good" said Blue Falcon "The Teen Angels and I are on our way to the Daily Planet. We'll meet you there. In the meantime, you guys try to find Luthor."

"Got it BF." Dynomutt told him "Dynomutt over and out."

"So our next step is to find Luthor, Dog Wonder?" Augie asked.

"That's right, Augie." Dynomutt replied. "This is where things become dangerous."

"Dog Wonder's right." Krypto nodded. "Lex Luthor is a very dangerous criminal scientist and is quite as dangerous as the Joker is to Batman."

"So you two had better stay here" April told Kevin and Andrea "We don't want you two getting hurt."

"Good luck Krypto" Kevin patted Krypto's head.

"I'll be okay Kevin" Krypto licked Kevin's cheek.

"Now don't get hurt Streaky Weaky" Andrea picked up Streaky.

"I won't." Streaky groaned.

"Good." Andrea kissed Streaky on the lips.

Streaky smiled before licking Andrea in the face.

After the two kids sneaked back into their bedrooms, the heroes are off to find Lex Luthor.

"Now Dog Wonder, do you have an image of Luthor in your hard drive?" Daphne asked.

"I believe I do." Dynomutt replied before trying to search through his hard drive for the image.

"Here, what about this?" Krypto asked as he produced an image of the criminal scientist and showed it to Dynomutt.

"Gee, thanks, Krypto!" Dog Wonder replied. "I think I may have misplaced my copy in my hard drive."

After scanning the image of Luthor, Dynomutt did his bit and a map of Luthor's whereabouts was shown in the map projected on the screen.

"Come on gang" said Shaggy "Let's go find Lex Luthor."

The gang all follows the Dyno-Map's guidance.

"Ruff, ruff and away!" Krypto followed the gang.

"Puppy power!" Scrappy added.

"Streak a doo!" Streaky followed.

Author's Note:

Looks like we've now got Krypto and Streaky joint our mystery team to stop Luthor. Now what of the Man of Steel himself? Are BF and the Teen Angels gonna find him? Stay tuned!
