The final confrontation takes place in Corona Mountain. Strategy: You'll face Bowser and Bowser Jr. in a giant hot tub of lava. Use the Rocket Nozzle to launch Mario onto the platforms above. Ground pound the weak points on the platforms to collapse them, sending Bowser and Bowser Jr. into the lava. You'll need to do this multiple times while avoiding their fire breath and cannonballs. Timing and precision are key.
