The Final Battle! (minigame)

Once the player became the star of every board in Story Mode of Mario Party 4, Bowser would steal all of his or her presents. The Player then enters the Final Battle Cube, Bowser's version of the Party Cube. The objective of the cube was to chase Bowser and retrieve the player's stolen presents.

The player starts with ten hearts, which serve as a life meter. Every time the player got hit, one heart would be taken off. If all hearts were lost, the player lost the mini-game.

The first and third sides of the cube involved hopping on platforms, some of which had fire jets. The player had to be careful not to fall into the magma; any character who touched the lava would instantly lose.

The second and fourth sides involved solving a puzzle similar to the one found in Lethal Lava Land in Super Mario 64. In the first puzzle, two Koopa Kids would try to hinder the player's progress by dropping flaming cannonballs and mini-tornadoes. In the second puzzle, Bowser himself would appear wielding a fiery boomerang.

The fifth side involved a mini-battle with Bowser. Five buttons are located around the perimeter of the area. By Ground Pounding three, an ephemeral triangle would appear, lightning striking anything in it a few seconds later. The goal was to surround Bowser with the triangle, lead him into it, and cause him to get shocked. Bowser could retaliate with his boomerang and flame breath. It took five shockings to down the King Koopa. He can charge, too.

Once defeated, Bowser would return the player's presents, and give him or her another present depicted in Bowser's likeness. However, the present usually had an evil twist to it. (Example: Bowser gave Luigi the Bowser TV, however, it only showed commercials)

The Final Battle was also an unlockable special mini-game.
