Three amazing months after Paradise returns to Equestria and after Opaline's defeat, there is a great reason to celebrate-- Queen Haven and Alphabittle's two-year dating anniversary! But as the celebrations begin, our heroes are pulled into another Unity Quest... this one revealing secrets from Mystery Incorporated's past. When Mystery Inc bumbles a case and nabs an innocent man by mistake, the gang is forced into early retirement from crime-solving. But it doesn't take long before their old friend Vincent Van Ghoul needs help and pulls the team right back into action. It all started one summer when Scooby, Shaggy and Daphne secretly tracked down 13 of the world's spookiest ghosts, and caught all but one. With the 13th ghost on the loose, the gang will have to leave their secrets in the past and settle some unfinished business. Bundle up and get ready for the icy slopes of the Himalayas with new friends, chilling car chases, crystal balls and spine-tingling spells in this terrifyingly fun adventure! (S3E1 of G5 Adventures)
