Overview[]
In this mission, Mario facing himself facing a new foe: Bowser Jr. Mario reached Bowser and his son at the end of the volcano in a floating, sun-shaped, slime-filled bathtub just above the peak of Corona Mountain. Bowser tried to kill Mario by breathing enormous gusts of flame and splashing slime at him, while Bowser Jr. assaulted him with Bullet Bills. Mario used F.L.U.D.D's Rocket Nozzle to produce a few massive Ground Pounds that tipped the bowl over, sending the Koopas to fall into a miniature island adjacent to Isle Delfino. Bowser confessed to his son that he had used him as a pawn, but Bowser Jr. then revealed to his father that he knew all along that Peach was not his mother, and that he was eager to challenge Mario again some time in the future, when he would be bigger, which filled Bowser with pride. They then decided to continue their vacation together. This must be done four times to defeat both Bowser.
