"Come on, guys. We have to hurry." Fred says as he takes the control panel.
"We have to get this control back before..." Fred says as they go into the monster-making room to see The Tar Monster, The Skeletons, The Zombie, and Red Beards Ghost along with the Masked Figure.
"Before exactly that happened." Fred says.
"At last I have you, Mystery Inc. and KISS. You'll never make it past my monsters." The Masked Figure says.
"We've taken these jerks before, gang. Let's do it again." Daphne says as Fred charges for the plug in for the control panel.
"Fred!" Daphne yells as Fred gets caught by The Tar Monster.
"It's not them you need to worry." The Masked Figure says.
"Now your stuck in my trap." The Tar Monster says.
"Daphne!" Fred yells as he throws the control panel to Daphne as she catches it.
"Daph!" Shaggy says as The Tar Monster goes after Daph.
"Run, Velma!" Daphne says as she throws the control panel to Velma a she catches it but gets caught by The Tar Monster as she throw the control Panel to Shaggy. Alexis and the guys then try to help the others but get caught by The Tar Monster.
"Soon your friends will be dead and there's nothing you can do about it." The Masked Figure says as Scooby backs into a fire distinguisher and gets an idea as he uses it to free Shaggy.
"Like frost bite never felt so good." Shaggy says.
"Stop him!" The Masked Figure says as he sends the monsters after Scooby as Scooby quickly makes his way over to the plug in after getting the control panel.
"You can't do this to me! Who do you think you are?" The Masked Figure asks.
"Scooby Dooby Doo!" Scooby says as he plugs in the control panel pressing a button destroying all the monsters and saving the others.
"My monsters!" The Masked Figure says as he falls down a place in the iron stairs getting caught. Everyone then runs over to Scooby.
"You did it! You saved us all!" Shaggy says.
"I know!" Scooby says. Later the group is walking out with the police holding the Masked Figure as the news come running over.
"Do you know the identity of the evil Masked Figure behind it all?" A news man asks.
"Well if our hunch is correct the evil Masked Figure is.." Velma says.
"No!" The Masked Figure yells as Daphne and Velma take off his mask.
"Heather Jasper-Howe." Daphne says as Patrick comes to the front of the crowd.
"But she was at the museum when the Masked Figure was on the roof." A news women says.
"You almost had me there, didn't you? Lucky for her, she had an assistant helping her with her evil plans. Ned." Daphne says pointing to a camera man as the police grab him.
"When I realized she was the evil Masked Figure he quickly changed into her costume." Daphne says.
"But why did she do it?" A news lady asks.
"Because Heather Jasper-Howe is actually Doctor Jonathan Jacobo." Velma says as she pulls a mask off Heather revealing to be Jacobo.
"The original Pterodactyl Ghost." Velma says.
"But how do you know this?" A news lady asks.
"A photo, taken of Jacobo in front of the Coolsonian. Jacobo supposedly died a year before construction even began." Velma says holding a picture.
"So Jacobo survived that fall off the prison wall." Shaggy says.
"Yeah." Scooby says.
"He also adapted the false Heather Jasper-Howe persona to turn the press against us." Fred says.
"Then he framed poor Old Man Wickles by putting that book and The Black Knight Ghost in his mansion." Daphne says.
"As if you getting the lead in My Fair Lady wasn't enough!" Wickles says.
"I wasn't an excellent Eliza! You were too act-y!" Jacobo says as the police put him in the car with Ned.
"And stealing my tater tots!" Wickles says.
"Velma if you want to go out with Patrick its ok." Space man says.
"Are you sure you really ok with it?" Velma asks.
"Yea I'm sure I just want you to be happy." Space man says. Velma then goes over to Patrick as the two start talking and smiling.
"Well guys its been fun but we need to head back to Kissteria." Star child says.
"Wait so you guys are like leaving?" Shaggy asks.
"Yea but don't worry we'll come back whenever you need us to help ya with a mystery. Lets get going guys." Star child says as he, Alexis, Demon, Space man, and Cat man leave.
