Bowser's Big Blast is a mini-game that can be found in Mario Party 2. It is very similar in its gimmicks to Bowser's Bigger Blast from Mario Party 4 and Cut From the Team and You're the Bob-omb from Mario Party 8. The minigame returns in Mario Party: The Top 100.
Gameplay
In this minigame, players take turns pressing the switches, trying to dodge the switch that detonates the Bowser Bomb. During the first round, there are five switches. In the second round, four, and in the third round, three. The round is ended if someone makes the Bowser Bomb detonate. When that happens, that player sulks before being blown off screen; at that point, they are "eliminated". There is no telling which switch will cause the bomb to blow.
Rules
Main: "Take turns pressing the plungers. If Bowser blows up on you, you're out. Last one standing wins!"
Tips: "Just because a plunger detonated Bowser once doesn't mean it will again... Or does it? Give it a try!"
