Bowser's Block Party is a boss minigame from Mario Party DS. In it, the player fights Bowser after he uses his Megamorph Belt to become Blockhead Bowser. Part of the minigame's name is a play on "block party."

Introduction
Bowser puts on his Megamorph Belt and transforms into the first form of Blockhead Bowser.

Gameplay
The player gets five hearts (served as a Health Meter), while Bowser has only three. First, he turns into a spinning top and spins around the arena, shooting fire from the golden Bowser Block. After a while, he cloaks himself in fire. Eventually, he stops, the flames dissipate, and he falls over. The player must then punch or kick the golden Bowser Block five times to defeat that form and turn him into his next form.

In Bowser's next form, he becomes a large cube 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 Bowser's last form, he becomes a snake-like trail of blocks, with the normal Bowser Blocks as a body and the golden Bowser Block as a 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 it stays uncovered for a moment. At that time, the player must punch or kick it five times.

Once the game is completed, the player has beaten Story Mode, unlocks Triangle Twisters, and obtains the Bowser's Megamorph Belt trophy. The player also gets the character's badge and figure.

Ending
After Bowser loses all three of his lives, he turns back to normal, collapses in defeat, and is crushed under a cube of blocks similar to Blockhead Bowser's second form. The player then celebrates.
