Barrel Baron

Barrel Baron is a minigame in the Extra Room of Mario Party 4.

Gameplay
In this minigame, the chosen player is in a hot desert with oil teeming under the grounds. Walking around with pickaxe in hand, the player must search for a spot that makes the controller rumble (or have a "!!" appear over the character's head if the Rumble setting is turned off). After the player chisels three times, a geyser of oil will come out. Small geysers are worth one point, medium ones are worth ten, and large ones are worth 100. The goal is to get as much oil as possible in 60 seconds.

Controls

 * – Move
