Defuse or Lose

Defuse or Lose is a 2-vs-2 minigame in Mario Party 5 and Mario Party: The Top 100. The minigame features the only appearance of King Bob-omb in Mario Party 5. In the background are some big Bob-omb-shaped sculptures. Also surrounding the players is a big group of Bob-ombs.

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

Gameplay
The objective of the game is to prevent the sparks on the fuses from reaching King 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. A player can extinguish two sparks at once by ground-pounding them where the fuses intersect. If a spark reaches King Bob-omb, that team loses.

Ending
When one team loses, King Bob-omb will explode, making the player's character, their teammate, and the Bob-ombs all fly away. In Mario Party 5, the remaining team will then perform their victory animations as the Bob-ombs clear the area.

It is possible to end this minigame in a draw. If both teams' sparks reach King Bob-omb at the same time, both King Bob-ombs will explode, sending both teams and their Bob-ombs flying. A rubble is created, smoking as "DRAW" appears on the screen.
