Blockhead Bowser

Blockhead Bowser is one of Bowser's forms, and the final boss of Mario Party DS. Bowser transforms into Blockhead Bowser via the Megamorph Belt. There are three types of blocks that Blockhead Bowser consists of: regular grey blocks, which are just normal blocks, Bowser Blocks, which can shoot out flame balls in all forms, and the golden Bowser Block, the weak spot, which can also shoot out flame balls, but only in the final form. It is fought in the minigame Bowser's Block Party.

Blockhead Bowser can morph into three different forms - a tornado, a huge block, or a trail of blocks. The form is impenetrable, except for the one golden Bowser Block, which has to be attacked by the player in order to defeat Bowser. First, Blockhead Bowser will form into a tornado and spin around, flinging fireballs and lighting itself on fire before falling over. When it falls, the player can attack the gold Bowser block. After it is hit five times, the blocks will separate and reform into one large block. The block will flip toward the player, shoot a fireball out a Bowser block on each side and flip again. Once the gold Bowser block is hit five more times, he will reform into a snake-like form. It will slither around the arena shooting fireballs. The gold Bowser block is wreathed in flame, so the player must wait till it slithers toward the middle and snuffs out the flames. This gives an opportunity to attack, but the player must be wary, as the block shoots fireballs in three directions. Once it is hit five more times, Bowser is defeated.
