After defeating Opaline in the kingdom of Warnerstock, Equestria has been peaceful, since Opaline does not have a servant to collect Sparky’s dragon fire. But the ponies’ temporary vacation is about to be over-- they are about to be sent by the Unity Crystals on another mission.

This time, the ponies, Shaggy, Scooby-Doo and his nephew Scrappy-Doo learn there are things even scarier than homework in this feature-length field trip into mystery and mayhem! The academic adventure begins when the boys sign on as gym teachers at Mrs. Grimwood's School for Ghouls, only to discover the pupils are (zoinks!) daughters of the world's most frightfully famous monsters!

But when the girl-ghouls and Misty are kidnapped by the evil spider witch Revolta (who is teaming up with Opaline) and her spider-bat flunkies, our heroes spring into action to rescue their friends in spectacular Scooby-Doo style!

Will our heroes save the day in time? And will an unexpected new friend find her place in this monster-infected world? This installment of G5 Adventures will remind everyone that new friends, monster or pony, can be found in the most unlikely places!
