"What's that!?" Scooby and Shaggy ask scaredly as they hear a creaking noise and hide behind Alexis as the group arrives back at the house.
"It's just a window guys." Scrappy says closing the window as Alexis steps away from Scooby and Shaggy.
"Come on. Read it." Scooby says being impatient.
"I will. Like keep your shirt on." Shaggy says as the ape comes out of nowhere and picks him up taking the clue and necklace from Shaggy before dropping him.
"Yikes." Alexis says seeing the ape before shifting to wolf form growling.
"The ape." Shaggy says as he grabs Alexis pulling her with him as he and Scooby get away from the ape except for Scrappy.
"Psst. Scrappy get away from him. Like don't mess around." Shaggy whispers trying to get Scrappy's attention.
"How'd he do that?" Scooby asks seeing the ape give Scrappy the necklace and the clue.
*Timeskip*
"Good thing I thought of that old mechanical horse huh uncle Scoob?" Scrappy asks gesturing to the ape who is riding the mechanical horse.
"Reah." Scooby says.
"Nice job Scrappy." Alexis says sitting in wolf form next to the two as Shaggy is in the house trying to use the phone.
*Timeskip*
"The clue says go to a place that covers the tide to find the last clue just pier inside but pier is spelled pier." Shaggy says reading the clue as they are outside of a boat house.
"Like by the water. You're right Shag. This boat house has to be the place." Scrappy says.
"Just think. The last clue to the whole family fortune is inside here. Okay guys let's split up and start looking." Shaggy says opening the door as they go inside. While searching close to the boat Alexis then hears Scooby scream ghost.
"What are you-oof!" Alexis shouts getting cut off as she gets tackled into the boat by Scooby and Shaggy.
"There's nobody there. You can be a pain sometimes." Shaggy says irritated not seeing anything.
"There it is. The finally clue. Quick Shag read it." Scrappy says as they are all sitting in the boat as Shaggy then finds the clue and a crown.
"It says no more riddles here ends the chase the treasure's in the fireplace." Shaggy says as he reads the clue.
"In the fireplace aye!? Thank you for solving the mystery for me fools. Farewell and good riddens." The skull ghost says as he drops a net over Alexis and the others in the boat before turning the motor on as the boat takes off while Alexis and the others try to get loose from the net.
"Like what happened?" Shaggy asks as the net comes off and the boat is lifted out of the water.
"How'd we get out of the water?" Scrappy asks.
"Oh we just thought ya's might like a lift. Get it? Lift up?" A voice asks laughing revealing to be Shreako, Meako, and Freako holding up the boat.
"Pipe down." Freako says as he hits Shreako into the water.
"The Boo brothers. Gee thanks." Scrappy says.
"Yeah thanks." Alexis says.
"Well you saved us but it's too late to keep the ghost from getting the treasure." Shaggy says sadly.
"What do you mean too late? No ghost beats the Boo Brothers. Spirit speed go!" Freako says as he and his brothers lift the boat and get going back to the house fast as possible.
*Timeskip*
"Haha I got it." The skull ghost says as Alexis and the others open the door and see him pull the lever on the fire place.
"Not yet you don't." Scrappy says.
"Like just hold it right t-there Mr. Ghost or whoever you are." Shaggy shouts trying to sound brave.
"Stand back nothing's gonna stop me now." The ghost says pulling out a gun as Alexis stands in front of the others protectively as gold and jewels come flooding out of the fireplace stopping the ghost as he lets go of the gun.
"Take a look at those diamonds!" Shaggy says seeing the jewels.
"Let's take a look at that ghost." Scrappy says as Shaggy pulls the skull mask off the ghost revealing it to be the Sheriff.
"The sheriff!" Everyone says in union.
"Somebody call me!?" A voice calls revealing to be a sheriff that looks like Sheriff Buzby.
*Timeskip*
"Like wow so this guy is your brother?" Shaggy asks seeing the real sheriff handcuff Buzby.
"Yep. My flagship brother T.J. likes to slap ship the tow cars and impersonate ghosts and me don't ya?" Rufus Buzby asks.
"Yeah. You goody goody brother." T.J. Buzby says.
"T.J. the mascaraed's over." Rufus says as he starts walking Buzby toward the door.
"I knew this treasure was here I knew it! All my life I wanted to get my hands on it and had it!" T.J. shouts angrily.
"Yeah for about twenty seconds." Shaggy says a little amused.
"And now we're gonna get you straightened out! Come on." Rufus says walks him out the door.
"Pretty amazing to think that guy could imitate all those ghosts." Scrappy says as they watch the sheriff take away Buzby.
"Oh I wouldn't too sure about that. Zoinks!" Shaggy shouts as he jumps into Alexis's arms as he sees a ghost before it runs into the pile of gold and jewels.
"It's just me." Scooby says revealing to be the ghost as Alexis puts Shaggy down.
"Well I guess there's no real ghosts here after all." Shaggy says as he laughs.
"Oh no!?" A voice asks.
*Timeskip*
"Like wow. What a meal." Shaggy says as they get done eating.
"You said it Shag. I'm stuffed" Scrappy says.
"Me too." Scooby says.
"It was delicious." Alexis says as they hear a gong and see Farquard with a giant dish on a cart.
"Dessert is served." Farquard says as he then laughs and walks away after bringing the cart over to the table.
"More food." Everyone says in union as they go to lift the lid off the dish and instead of finding dessert they find Shreako, Meako, and Freako.
"Hey!" Shaggy shouts.
"Oh hi guys." Freako says.
"I guess we take the cake. Ya get it? Take the cake!" Shreako says laughing.
"Oh we're ever so sorry we ate but we we're just so hungry." Meako says apologizing.
"Aww that's okay. You deserve it. As a matter of fact you deserve a lot more right guys? You Boo Brothers were such a big help that we're leaving you guys this whole house." Shaggy says.
"Yeah." Alexis says.
"To haunt for as long as you like." Scrappy says.
"Wow!" The brothers say in union.
"That's great but where're you guys going?" Freako asks.
"Like we're splitting for home." Shaggy says as they start walking.
"Well actually Shaggy I'm staying here." Alexis says.
"What?" Shaggy asks as he looks at Alexis before Shreako appears beside her.
"Let's just say someone has been pretty convincing on giving me a reason to stay." Alexis says as she smiles at Shreako.
"Don't worry. I'll look after her. But what're you guys gonna do with all ya's diamonds?" Shreako asks.
"They're going to the Beauregard trust fund for orphans." Scrappy says as they start walking again.
"Gee. That's sweet." Freako says.
"Goodbye." The Brothers and Alexis say in union as they watch Shaggy and the Doo's get into the truck.
"Goodbye." Shaggy and the Doo's say as they leave.
