Bowser's Block Battle

Bowser's Block Battle is the final boss minigame featured in Mario Party 9. This and Bowser Jr. Breakdown are the only minigames played on Bowser Station, and players cannot choose from three other boss minigames. The same happens on DK's Jungle Ruins.

Introduction
The view will be on the players, standing on a stone platform floating in space. The view will shift to the front of the platform as Bowser appears, roars menacingly, increases in size and pulls some dice out.

Gameplay
Players must attack Bowser by rolling dice marked with their own faces and Bowser symbols on the remaining sides. These dice are not typical Dice Blocks, but objects that players can pick up and throw if they want tp change what faces up. After 10 seconds, the rolls will be set and dice can no longer be picked up (dice that are held by a player when the time limit expires will be thrown automatically and the roll will be included). The dice that show the players' faces will be converted into energy balls that players can shoot at Bowser for points. Players attack in decreasing order of number of dice with their faces shown, so those with the most dice make the first move and those with the least dice take a turn last. Players with equal numbers of dice with their characters' faces attack together. After every player attacks, if any dice show Bowser's symbol, he'll attack by spitting a trio of fireballs once for each dice, and anybody hit by a fireball will lose one point. Bowser will then throw a new set of dice onto the stage, and the process will repeat.

When Bowser's health drops below half (signified by his health bar dropping past the white line in the middle and turning red), he will increase in size and make the battle more dangerous. After tossing the dice onto the field, the Koopa King will grab the stage and tilt it side to side to complicate the players' attempts to roll the dice. If he gets any chances to attack, the fireballs will be larger and faster than before, making them more difficult to avoid. He also gains one new attack: after everyone has attacked with their dice, Bowser will roll a large, spike-edged die with images of the six bosses on it. (Fortunately, this die won't crush any players it lands on top of, so players can still make it tumble and change the image it shows.) After it lands, the camera zooms in to show which image is rolled. The die disappears in a puff of smoke and the players must evade one of six elaborate attacks:


 * Wiggler walks around the arena three times before leaving.
 * King Bob-omb drops into the middle of the arena and makes Bob-ombs fall out of the sky.
 * King Boo will summon groups of Boos that spin in gradually-expanding circles. The first group spins clockwise or counterclockwise and the second group spins in the opposite direction.
 * Blooper floats near the front of the arena (where Bowser is) and tosses ten Urchins at the players.
 * Chain Chomp drops into the middle of the arena and charges at the players. When it hits a wall, it will change direction. Players must dodge a few charges before Chain Chomp leaves the arena.
 * If Bowser rolls his own image on the dice, he'll launch five waves of fireballs straight ahead. The waves alternate between three and four fireballs, forcing players to weave between them.

Ending
Once defeated, Bowser will fly into the black hole behind the battlefield and explode, revealing several Mini Stars.
