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 Mega Morph Belt to become Blockhead Bowser.

Gameplay
First, he turns into a top and spins around the arena, shooting fire from the Golden Bowser Block. After a while, he gets covered in fire. Eventually, he stops and falls over. The player then punches or kicks the Golden Bowser Block five times to defeat that form and turn him into his next form.

In his next form, he becomes a large block and moves like a Tox Box. After moving, he shoots fire from Bowser Tiles on his side. The player must punch or kick the Golden Bowser Block five times when it comes to the ground.

In his last form, he becomes a caterpillar-like thing, with the normal Bowser Blocks as body and the Golden Bowser Block as head. It moves around the outside and the Bowser Blocks shoot fire. The Golden Bowser Block is at first covered in fire. When it stops, it shoots fire from its side, and stays uncovered for a moment. At that time, the player must punch or kick it five times.

After losing all three lives, Bowser turns back to normal, collapses in defeat, and is crushed under a cube of blocks similar to Blockhead Bowser's second form, the player beats Story Mode, unlocks Triangle Twisters, and gets the Bowser's Megamorph Belt Trophy. Also, the player will also get the character's badge and figure.
