In a world where ponies are dumb. Oh, and the CMC was never formed.
There has been a Ghost have sited at Ponyville Elementary, turning ponies into stone whenever it mane flies up and stares into the glowing red eyes. For safety, groups of five are formed with every student, forming a band of meddling kids ready to solve this ghost and stop the attacks before a student get to turn into a lawn ornament.
I blame my Scooby-Doo month for this, I'm so sick and tired of Scooby-Doo at the moment, I watch Scooby-Doo! Adventures: The Mystery Map! Look it up, it a puppet version of Scooby-Doo and it's terrible.
