Night of the Living Costumes

When the gang receive a call from the curator of the Canterlot Mystery Museum they discover that the costumes of their past monsters are coming to life
== Script ==
(We open on nighttime in Canterlot where at the Canterlot Mystery Museum, a guard is making his rounds and he hears sounds and turns to see something scary and runs of screaming into the night, we blackout and fade back to the gang in their clubhouse at daytime)
Snails:Like what's for lunch man?
(Big Mac is at the desk with his feet on top of one another and is reading the paper)
Big Macintosh:I wouldn't think Snails it's just 9:30.
Snails:Oh. I was just thinking.
Spike:I agree with Snails. I'm kind of hungry.
Sci-Twi:You're always hungry and agreeing with Snails on food.
(Phone rings and Twilight answers it)
Sci-Twi:Hello, Canterlot Mystery Solvers! Yes of course we're serious. There is? The museum's being over run by the costumes? Don't worry, we'll take care of it. (Hangs up)WE GOT ONE!!!!!!!!!! The museum's haunted by our old monsters! Come on!
(They head for the van and drive to the museum and make it)
Big Macintosh:Hello? We're here.
Curator:I'm glad you came so quickly. We've had quiet an attack. And just last night, we've had an attack. Only it was last night.
Rarity:Yes sir, you told us.
Spike:Yeah, already.
Curator:Would you like to know what I think is bringing alive the costumes?
Big Macintosh:Eyup. What is it and why?
Curator:A sprit called the Possessor. A demonic ghost that posses anyone or anything. I assume that it's possessing our exhibits.
Big Macintosh:That's all we wanna know.
Spike:I say we head for home.
Snails:My thoughts exactly Spike.
Sci-Twi:Not until we solve this mystery.
Curator:I think you kids should look around for clues.
Rarity:I say we head to the exhibit hall.
(Cuts to the exhibit hall where the door opens and the gang are in the entrance)
Rarity:My word, this is like going back to our greatest mysteries.
Sci-Twi:I know. Look, there's the Spook Clown, and there's the Ghost of Redbeard. Only unlike the Scooby-Doo one this one had black pirate clothes like in the opening of Mask of the Blue Falcon.
Big Macintosh:Eyup. And there's the Phantom of Elias Kingston. The glowing green version with pupilless eyes who wore a black trenchcoat and not a dark blue and purple one like the Scooby-Doo one. And there's the Ghost of Captain Cutler. Only it looked like the one in that Scooby-Doo crossover episode with Batman: the Brave and the Bold.
Snails:Like look man. It's the Phantom Ninja, and there's the Mummy Mumbler. And the Headless Ghost and the Haunted Armor. And like that's from segments of the animated cartoon of the Three Stooges. 
Spike:And speaking of the Three Stooges there's the Ghosts of the Three Stooges.
(The Possesor comes and is a mist with giant red eyes)
Possesor:I am the Possesor, cower in my terror for I'm going to get you!
