After their previous encounters on their Unity Quests, Sunny and her friends wonder if more different kinds of ponies that left Equestria before magic disappeared... and they need to know that the land is united once again. Luckily, they earn their chance to find out when they are resummoned back to the mortal world by the Unity Crystals for another mission.

They are quickly reunited with Mystery Incorporated to unravel a bewitching case of ghostly deeds and spine-tingling suspense in this Scoob-tacular adventure.

When the gang meets up famous fright-writer Ben Ravencroft and his pony pal Autumn Rain, Ben and Autumn quickly invite the teams to Oakhaven, New England, for the annual harvest festival. Things take a supernatural detour when they learn the place is haunted - by Ben's ancestor, Sarah Ravencroft! Will the mystery reveal that Sarah was a good-hearted wiccan... or a spell-casting witch?

Before you can say "Scooby snacks" or "Hoof to heart", the gang is on the case, tangling with bumbling mummies, monster turkeys - and (Zoinks!) a ghostly secret in the Ravencroft's family past!

With old and new friends at their side, it's a G5 Adventures story at its spine-tingling best!
