Mario, Luigi & Porru: Two United Worlds

Hello, its-a me, Mario! My brother Luigi and I have noticed a portal with characters from another world coming to the Mushroom Kingdom! There is one more villain apart from Bowser! We have a new friend called Porru! Lots of things happen here! We have to battle from weak enemies to powerful bosses! We always have to save games and heal ourselves! This mixed adventure is very dangerous, hard and long!
