Bowser's Block Party

Bowser's Block Party is a boss minigame from Mario Party DS. In it, players fight Bowser after he uses his MEGAMORPH BELT to become Blockhead Bowser. Here's his forms:

Top
In top form, he will spin around and shoot fire. When he stops for a bit, whack the heck outta the Golden Bowser Block.

Thwomp
Bowser, after 5 damage, will become thwomp form. The transformed koopa king will smash around, shooting fire. Come near and whack the heck outta his GBB before he shoots it.

Train
After another five damage, he will be in train form. He will go around on fire and shoot some, and when the fire goes and he goes through the middle and shoots fire. Then hit the Gloden Bowser Block. After five hits, he's finished off. He faints and is crushed by his thwomp form.
