Bowser's Block Party

Bowser's Block Party is the final Mario Party DS boss minigame, the player must defeat Bowser in 3 forms: Top, Block, and Snake.

Intro
When Mario and his friends walk in the arena, Bowser takes out a powerful new weapon that he straps around his waist. He then transforms into a large top made of grey blocks and the game starts.

Gameplay
In the first form, he spins like a top and when it stops, that's your chance to attack. 5 punches or kicks, and the first form is defeated. Next is the large block form which is moving like a Tox Box. Again, 5 good punches and kicks defeats it and the final form kicks in. The final form is the snake which slithers around for a second or two and then it shoots fire. 5 more punches or kicks and Bowser is defeated! The weakness: the Golden Bowser Block!

Ending
If Bowser is defeated while playing story mode, a series of cut scenes will play, followed by the unlocking of Triangle Twisters, the credits, Sound Test and the 5th board, Bowser's Pinball Machine.
