Whenever Bowser shoots the giant spike balls, you suck them up with your poltergust 3000 (vacuum cleaner) and shoot them at bowser's head. Then King Boo comes out and you suck his hp out, and beware of Bowser shooting ice at you. Keep doing this and you will eventually beat him.
Whenever Bowser throws a spiky bomb, vacuum is so that it's at the end of your vacuum nozzle. when bowser bends down, stop vacuuming the bomb to fire it at his face.when king boo comes out, start vacuuming. repeat the process.
