When Grant finds a big blue box, he meets the Doctor and his assistant Derpy Hooves, AKA Ditzy Doo. Before Grant could get to know them better, the fiend before the Darklings, Trixie and the Gilda attack appears. He is Zool, the Dark "Puller of Strings". A being of chaos. Zool is the reason why Grant is no longer human and his goal in Equestria is to see this world rip itself apart. What is Grant and the Doctor to do?
