With Maltazard now seven feet tall and Arthur still two inches small, our hero must find a way to grow back to his normal size and stop the Evil M once and for all, with the help of Selenia and Betameche.

Maltazard, the Evil M, is now 7 feet tall and evolving among the humans, causing terror wherever he goes. His goal is simple: forming an army of giant henchmen and ruling over the universe. Meanwhile, Arthur is still a Minimoy, and thus in a state where he's unable to fend him off. With the help of Selenia and Betameche, he hatches a plan to regain his usual size: all they must do is infiltrate Arthur's house through the pipeworks, catch an electric train from his bedroom to his grandfather's study and find an elixir that will make him grow back to his human size. Sounds simple enough, if it weren't for Darkos, Maltazard's own son, hot on their tails.—Happy_Evil_Dude

The evil Maltazard is now over two metres tall and causing terror wherever he goes. His goal is simple: forming an army of giant henchmen and ruling over the universe. Only Arthur, who's still shrunken, can thwart his plans, but first he has to get back to his bedroom and return to his normal size.

Everyone must put aside their differences and team up to defeat a common and major enemy who plans to destroy multiple worlds and everyone in it. Everyone must come up with a plan that would defeat the enemy and save everyone and restore peace.—RECB3
