"Correction the new and improved Scrappy. Because I Scrappy Dappy Doo have absorbed enough energy to rule the world with my all powerful army. And I brought you here puny pathetic Mystery Inc. and Kiss to witness my moment of triumph. All I need to complete my transformation is Scooby Doo!" Scrappy says as he grows into a monster.
"Me!? Don't you mean Melvin Doo?" Scooby asks.
"Seize them!" Scrappy says.
"Like let's get out of here." Shaggy says as he and Scooby try running away.
"Haha! Take that pretty boy!" Scrappy says as he hits Velma and Fred sending them both flying back.
"This is totally ungroovy Scoob!" Shaggy says as he and Scooby run away from Scrappy.
"Scooby Doo where are you!?" Scrappy says. Velma then whistles for Alexis, Space man, Demon, Star child, and Cat man to jump in.
"We gotta tip over the protoplasm fad." Velma says.
"How?" Fred asks.
"The pincer come on." Velma says as she takes off running or the pincer but some guards tackle her.
"Fred's just got his groove on." Fred says as he uses the hook on the end of a rope to take down to guards as Alexis and Space man take down the one holding Velma. Alexis then sees that Scrappy has Scooby and she and Cat man go to try to help him but Scrappy hits Alexis and Cat man back.
"Scrappy down! Sit! Bad Scrappy!" Scooby says as he flicks Scrappy's nose making him roar at Scooby.
"Let's finish this puppy now! Now!" Scrappy says.
"No! No we cant!" Scooby says as Scrappy starts trying to take Scooby's protoplasm with the pincer and Scooby tries to keep his protoplasm from being taken as someone falls through the air vent and knocks over the protoplasm fad and people's protoplasm then start flying back to their owners as Daphne releases the disco ball as monster come out of the people and then blow up from the light reflecting off the disco ball.
"Mystery Inc. and Kiss! This ain't over! Not by a long shot! I'll rock you and sock you and crush you like-" Scrappy gets cut off as he feels something poke his shoulder and sees its the pincer and sees Shaggy controlling the pincer.
"Like dude." Shaggy says.
"What!?" Scrappy asks.
"Your a bad puppy!" Shaggy says as he uses the pincer to take the damon ritus off of Scrappy and release the remaining protoplasm he absorbed and Scrappy starts going back to his normal self.
"Come on I can still take ya put em up you mangy mutt. I'll-" Scrappy gets cut off by Scooby hitting him and sending him at a wall.
"Is that all you got?" Scrappy says as Scooby just shrugs his shoulders. Fred then goes over to Daphne as she slides down the air vent on a rope.
"Hey Daph!" Fred says as he goes over to Daphne.
"We did it." Daphne says.
"Yes we did." Fred says as he and Daphne the kiss before Daphne pushes Fred off her.
"Fred! Cut it out." Daphne says as she and Fred smile at each other before Daphne sees Star child and sees him sad.
"I'll be right back." Daphne says as she goes over to Star child.
"I'm sorry Star child I hope we can still be friends." Daphne says.
"I'm alright with that darling." Star child says as he smiles at Daphne. Shaggy then hears some kind of metal banging and opens a door that reveals the real Mondavarious.
"Thank you so much." Mr. Mondavarious says as he leaves. Space man then goes over to Velma and picks her up in a hug and spins around once thanking her and telling her they did it. Space man and Velma then look into each other's eyes.
"Your fogging up my glasses." Velma says as they then kiss slightly and smile at each other. Alexis then smiles as Shaggy and Scooby are reunited as well as Shaggy with Mary Jane. Alexis then feels a pair of arms around her and sees Cat man and hugs him back. They all then go back to the hotel were the authorities are and the news is.
"Can you tell us how you solved the case?" A news women asks.
"Yes. Well it all started when I was giving a speech on my new book and- I really think the Velmster should take it from here." Fred says.
"Through the combined intunative powers of Mystery Inc. and Kiss we discovered that the real villain behind this mystery is in fact Scrappy Cornelius Doo who sadly was corrupted by the power of the damon ritus." Velma says as police then bring Scrappy to a police car in a dog crate.
"Oh get over it! So I got a little cranky!" Scrappy says as the police put him in the car with his accomplices.
"Geez Scraps! No reason to freak out like a jerk and try to kill all humanity!" Shaggy says.
"I would have gotten away with it too if not for you meddling-" Scrappy then gets cut off by the police closing the door.
"Now that Mystery Inc. and Kiss back together do you have any comment on the mud ball ghoul who been terrorizing London?" The news lady asks.
"Whatever the case Mystery Inc. and Kiss will be there." Fred says putting his hand out.
"Solving mysteries man." Shaggy says as he puts his hand in followed by Scooby, Alexis, Star child, Cat man, Space man, and Demon.
"Righting wrongs." Daphne says as she puts her hand in.
"Looking for clues and kicking butt." Velma says as she puts her hand in and they toss there hands up in the air.
