The story starts off with Mario announcing he is retiring, the kingdom is shocked and sad knowing that there hero is leaving but they get over it quickly, knowing how much he has done for them. Mario then travels to the far outskirts of the Mushroom Kingdom called the lost lands! Next he moves in to a small cottage. The next day he comes outside to find that his clothes that he hung on a rack to dry were now more wet then before!?! He looks around seeing many puddles of water... He then turns around to see a huge smoke cloud rising from the Kingdom. Mario rushes back into action but... When he arrives he sees that the 170ft walls protecting the mushroom kingdom were now spilling water out of them. Why you ask? Because someone destroyed the kingdom dam. Luigi and mahershalla The Smartest Toad In Town, tell Mario that this was browser's doing. Mahershalla also says that "Bowser has never been so smart and coordinated with his attacks, there is no way it was only just him" They all then hear a loud horn. Next they see general koopa flying in with bomb squads. The Mario brothers then get ready for the biggest battle of their lives! .
