The Final Battle! (minigame)

Once you became the star of every board in story mode of Mario Party 4, Bowser would steal all of your presents. You would then enter the Final Battle Cube, Bowser's version of the Party Cube. The objective of the cube was to chase Bowser and retrieve your stolen presents.

The first and third sides of the cube involved hopping on platforms. You 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 your progress by throwing obstacles at you. In the second puzzle, Bowser himself would try to stop you with a fiery boomerang.

The fifth side involved a mini-battle with Bowser, where you would have to electrify him before he killed you with his boomerang and flame breath.

Once defeated, Bowser would return your present, and give you another present, 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.
