Hint: The Final Battle:
To win The Final Battle, jump across the turning platforms with A. Once you reach the other side, you will have to solve a puzzle. Ground-Pound the three pieces to form a Bowser Kid. The new zone will be like the first, but with three flames coming out of the tiny pillars. Make your way across again. You must now solve a larger puzzle with little pieces. Once you complete the puzzle, go left to face Bowser. Stomp three buttons. It will form a triangular beam. Make sure Bowser is lured inside the triangle. He will get shocked. Do this five times to defeat Bowser.
