Balloon of Doom

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

Gameplay
In Balloon of Doom, each player tries to inflate a balloon with Bowser's picture on it as much as possible without making the balloon explode. 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. As with other Bowser mini-games in Mario Party 4, the game is heavily luck-based; no matter how much everyone tries to manipulate the pump, someone is eventually going to have to pop the balloon. However, there are warning signs that the balloon is close to bursting:
 * The Koopa Kid behind the balloon (to Bowser's left) starts backing away from the balloon as it gets larger; when it's nearly at its limit, he'll take cover behind the pillar flanking the throne.
 * The fan-holding Koopa Kid to Bowser's right begins hiding behind his fan when the balloon is almost ready to pop.
 * The three players not currently on the pump visibly and audibly cringe when the pumping player perform their Ground Pound.
 * Bowser's pose changes as the balloon gets bigger; he starts leaning on his right fist instead of his left once it's about halfway full, then subtly leans even further to the right when it's almost at its maximum size. At the latter point, he also uses new lines of dialogue, indicating anticipation for the inevitable.

When a player overinflates the balloon, there is a pause after they land on the pump before the balloon pops. The other three players flee as Bowser becomes angry and uses his fire breath on that player, resulting in a loss for that player.

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.
