Balloon of Doom

Balloon of Doom is a Bowser mini-game in Mario Party 4.

Gameplay
In Balloon of Doom, each team of players tries to inflate a balloon with Bowser's picture on as much as possible without making the balloon explode. If a player happens to burst the balloon, Bowser will become very angry and use his fiery breath on that player. Each player has a turn to stomp on the balloon pump to inflate the balloon. Higher Ground Pounds pump more air into the balloon, so players can manipulate how much air they wish to pump into it.

On a side note, if the player does not even attempt to inflate the balloon within the five-second time limit, they will automatically lose and suffer Bowser's fire breath.
