The Final Battle! (minigame)

Once a player become the star of every board in Story Mode of Mario Party 4, Bowser will steal all of the presents. The player then enters the Final Battle Cube, Bowser's version of the Party Cube. The objective of the cube is to chase Bowser and retrieve the player's stolen presents.

The player starts with ten hearts, which serve as a Health Meter. Every time the player gets hit, one heart is removed. If all hearts are lost, the player loses the minigame.

The first and third sides of the cube involve hopping on platforms, some of which have fire jets. The player has to be careful not to fall into the magma; any character who touches the lava will instantly lose. The first side has a path of four platforms, while the third side has two paths with six platforms overall.

The second and fourth sides involve solving a puzzle similar to the one found in Lethal Lava Land in Super Mario 64. In the first has three pieces of 2x2 puzzle, which the player must Ground Pound to move. Two Koopa Kids try to hinder the player's progress by dropping flaming cannonballs and mini-tornadoes. The second has eight pieces of a 3x3 puzzle, and Bowser himself will appear wielding a fiery boomerang.

The fifth side involves a minibattle with Bowser. Five buttons are located around the perimeter of the area. By Ground Pounding three, an ephemeral triangle appears, lightning striking anything in it a few seconds later. The goal is to surround Bowser with the triangle, lead him into it, and cause him to get shocked. Bowser can retaliate with his boomerang and flame breath. Later on, he will move while shooting flames and charge at the player. It takes five shocks to down the King Koopa. Be warned, however, that the player can be damaged by the lightning shock as well.

Once defeated, Bowser will return the player's presents, and give them another present depicted in Bowser's likeness.

The Final Battle is also an unlockable special minigame.
