Normally, when a pony pops their horseshoes, it's a bummer for everypony. An even bigger bummer is when Twilight and her friends die. The biggest bummer is when Ponyville suffers six annoying pony-ghosts spreading scares and ectoplasm everywhere.
Princess Celestia has a plan to fix this, however, but the Mane Six are going to hate it.
Mild sex and drug humor, but nothing squishy.
Cover Art is "Mane 6 In A Graveyard" by Macgrubor.
