When a scientist creates the world's first electrical appliance, he makes the mistake of trying to use magic on it. Magic and technology do not mix and all of Equestria's inhabitants are sent to a strange world where everything is made up of data. Some ponies are paired up with creatures called Digimon and must adventure to find a way home but Derpy is fed up of being judged by other ponies. She won't let Doctor Whooves help everypony get home.
For added fun and epicosity, play these whilst somepony's Digimon Digivolves! Play until the end of the fight sequence after they have evolved.
