Defuse or Lose

Defuse or Lose is a 2 vs. 2 minigame in Mario Party 5. The mini-game features the only appearance of Big Bob-omb in Mario Party 5. In the background are some big Bob-omb-shaped sculptures. Also, surrounding the player are a big group of Bob-ombs.

Introduction
The game first shows Big Bob-omb on the verge of exploding. Once it does, the three fuses attached to it will begin to burn. The screen will then zoom out and show the sparks traveling across one team's set of fuses before the screen splits.

Gameplay
The object of the game is to prevent the sparks on the fuses from reaching Big Bob-omb. To do this, players and their teammate must Ground Pound the three fuses, which follow a set trail. The fuses will rekindle not too long after they are extinguished, so the players must ground pound them again. If the fire/spark reaches Big Bob-omb, that team loses.

Ending
When one team loses, Big Bob-omb will explode, making the player's character, his or her teammate, and the Bob-ombs all fly away. The remaining team will then perform their victory animations as the Bob-ombs clear the area.

 * Advice – "Look where the fuses cross each other to slow two sparks with a single Ground Pound."
