One day, while Twilight was having tea with Fluttershy and Discord, a strange, metal wagon appears from the Everfree Forest. From it came a group of familiar-looking otherworldly creatures who call themselves the Aquabats who inform them that they were chased into their world by an evil creature named Space Monster 'M'. Join Princess Twilight Sparkle, her friends and Aquabats as they battle a slew of Changlings, comic book thugs and various other familiar faces, all in the effort of getting the Super Magic Power Amulet and Discord's body back from the newest threat to Equestria.
