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 becomes very angry and use his fiery breath on that player, resulting in a loss for 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 a player does not even attempt to inflate the balloon within the five-second time limit, the player automatically loses and suffers Bowser's fire breath.
