Scooby and the Gang investigate a ghost haunting the Canterlot High Garden Club
== Script ==
(We open on daytime at Canterlot High where in the garden Wallflower Blush is planting new flowers)
Wallflower:Boy this is great. Ever since the memory stone incident, I've got my own club.
(Wind blows)
Wallflower:What the?
(A transparent hooded ghost appears)
Invisible Garden Phantom:I am the Invisible Garden Phantom, leave my garden at once, this is your only warning.
(Wallflower runs off screaming we blackout and fade to the Rainbooms (Minus Twilight) in the band room)
Rainbow Dash:This is 90% cooler dudes!
Rarity:My goodness Rainbow Dash, what happened to saying 20% cooler?
Rainbow Dash:Trying to say something else Rarity.
Fluttershy:I can't believe Twilight is at home today.
Applejack:She'll be back tomorrow Fluttershy.
Fluttershy:Oh ok.
(Wallflower comes running in)
Wallflower:Rarity! Get Spike! Twilight! Snails and Big Macintosh!
Rarity:Why? What for Wallflower?
Wallflower:I saw a ghost in my garden! He called himself the Invisible Garden Phantom!
Rainbow Dash:If he's invisible then how'd you see him?
Sunset:Rainbow!
Wallflower:You gotta help!
Applejack:Calm down Sugarcube. It'll be alright. Everything'll be alright.
(Cuts to the Mystery Machine driving through Canterlot)
Fred:Well gang, the case of the Deadly Virus Phantoms was last week, the Ghost Ship Lookout was also last week, The Russian Collaborator case was a month ago.
Velma:Yeah it looked like the Ghost of Dr. Coffin. Then there was the Democratic Ghost. The Werewolf Zombie was really old Mr. Johnson.
Daphne:The mysteries in our neighboring town Crystal Cove considered the Ghosts of the Three Stooges, the Haunted Scarecrow, the Jackal Lanterns. The Airplane Monster.
Shaggy:And like don't forget the Trash Monster of Scranton. And yesterday we caught the Headless Horseman of Coolsville Bank.
