In top form, he will spin around and shoot fire. When he stops, hit the Golden Bowser Block.

Thwomp
After Bowser takes five damage, he will become thwomp form. He moves like a Tox Box. The transformed koopa king will smash around, shooting fire. Come near and hit the Golden Bowser Block like before.

Train
After Bowser gets more damage, he will be in train form. He will go around and will shoot fire. Then hit the Gloden Bowser Block. After five hits, he's defeated. Bowser faints and he is crushed by his thwomp form.
