The same way you beat him the first time - grab him by his tail, swing him around, and throw him into one of the bombs around the arena. This time around, however, he tips the battlefield to try and throw you into the lava, so be careful.
just beat his mission
You beat the game when you are in Bowser's Castle in World 8 and beat Giant Bowser and Bowser Jr. Then you save Princess Peach.
Him, Bowser Jr., Magikoopas, Hammer Bros, Dry Bones.
you beat Bowser by studying his forms carefully and that golden Bowser block well you kick and punch it so if you have that game write this down and go beat Bowser!
