A/N: Ta-Ta-Ta-Ta-Ta-Ta! First Inside Out/Scooby Doo crossover!

September 22nd, 1979

Have you ever looked at someone and wondered, What is going on in their head?
Well, I know. What's going on in Scrappy's head, anyway.

"Uncle Scooby?"

Joy slowly looked around. "Uncle?" He didn't where he was, or what he was doing, or how he knew the older dog was his uncle…

A slow grin spread across Scrappy's Joy's face. "I have an Uncle!" He said happily, reaching for a button.

"Hi!" Scrappy said happily. "I'm Scrappy Doo!"

It was me, Scrappy, and him...for 24 seconds.

"Nobody scares Uncle Scooby like that!" A bright red pup had somehow appeared next to Joy as he watched Scooby run from a ghost in terror.

"Lemme at him!" He said, pushing a lever forward full throttle.

"Whoa!" Shouted Joy in surprised as they lurched forward slightly, grabbing the control room to hang on.

He and Anger's eyes met.

They grinned at each other.

"I wonder what this does?" Asked Anger, pointing at a button labled, Puppy Power.

"Try it and see, try and see!" Joy urged.
Anger struck it.

"Ta-Ta-Ta-Ta-Ta-Ta! Puppy Power!" Blared through the room.
BLAM! The force of impact knocked over the scarecrow.

"Awesome!" Said Joy. "I wanna try!"
Next came Sadness…

"The Blue Scarab, A criminal?" Scrappy asked in shock.

"That's awful!" Said a turquoise pooch inexplicably wearing glasses gasped, reaching for a button. "Scrappy loves the Blue Scarab's comics!"

"This is enough to make a doggy lose faith!" Scrappy exclaimed sadly. "Oh, no."

Sadness gulped, wiping away a tear.

"OK, maybe later, dude!" Anger said, shoving away Sadness. "There are people watching!" His eyes narrowed. "And a blue baddie to splat."

Then Disgust…

"I can't believe that we somehow mistook Uncle Scooby for the Scarab." The lime green emotion grumbled. "How does that even happen?"
"Dunno."
"Sorry…"
"Well, excuse us. Where were you while we were making the Scrappy trap?" Anger swaggered up to the newest emotion.

Disgust threw his paws up. "What? It's not my fault I didn't exist a second ago!" He argued, prompting an annoyed grunt from Anger.

Last of all, Fear.

"We're gonna be sliced and diced for sure! HEEEELLLLPPPP!" Shaggy shouted, running down the conveyor belt, away from the slicer.

"Alright," Said Fear, "Strap in your seat belts everyone. We're gonna die!" He shouted, grabbing a lever.

"We're going to die? So soon?!" Sadness's lower lip started to tremble.

"Maybe there's a way out of this…" Joy mused. He perked up. "I know! Let's leap off the conveyor belt!"
"Are you nuts?!" Anger demanded. "We'd break our necks!"
"We couldn't just leave Uncle Scooby like that!" Disgust insisted.

Joy blushed. "Of course not!"
"Can we faster?!" Fear shrieked.

And now you've met all of us...little did us or Scrappy, know, life was just about to take a turn for the weird…

Five Minutes Later

"And that's the metaverse." Shaggy finished up to their newest member, Scrappy Doo.

"Wait," Said Joy. "Wait, so, everything that just happened before...in the episode...that wasn't real?"
Disgust nudged him. "Weren't ya payin' attention? Shaggy said that it was all real!"
"But this is just realer," Added Anger.

"But, But, guys, that doesn't make sense! I mean, what's realer then real?" Fear asked. "This ain't adding up!"
Anger pushed aside Fear. "It doesn't matter."
"It does too!" Fear insisted.
"It does not." Anger answered adamantly.

"What should we do?" Asked Joy as the three other emotions watched them fight.

"I don't know, I'm kinda new at this." Sadness explained.
"We're all new at this!" Disgust snapped. "Guys!" He shouted, trying to get Fear and Anger's attention. "Guys!"

"Well, Scrappy?" Asked Fred.

Scrappy's eyes had gone blank, and he stood as though in a stupor.

"He's gone into metashock," Velma stated. "Remember when we did that?"
"Oh, yeah!" Daphne's eyes lit up. "Was it really only ten years ago?"
"Yep, ten years of mysteries," Said Fred fondly.

"And possibly lots more, thanks to this little guy." Said Velma, scratching behind Scrappy's ears. "Well? How are you likin' being with the gang, Scrappy?"
Joy turned away from the bickering long enough to notice Velma through the window.

He smiled, rushing to the control seat.

Scrappy blinked, coming out of metashock. "I love it!" He said, wagging his tail.

A/N: According to Mark Evanier, without Scrappy, ABC would have cancelled Scooby and they would have gotten a new pilot instead. Scooby and the gang were pretty scared about their show being cancelled, so when the show got renewed with Scrappy, they were very, very happy and relieved.

There will be more of this. This is only the beginning…
