Bob-omb gang

The Bob-omb Mafia is a large group of Bob-ombs who are led by the Big Bob-omb. They made their only appearance in Mario Party Advance. While traveling through Shroom City the player encountered several people who mentioned the mysterious leader of the Bob-omb Mafia was located in a secret room somewhere in Shroom City. Finding a hidden bottom floor in the mushroom condo the player found Big Bob-omb and challenged him to a game of chance. Earning the respect of Big Bob-omb, the player gained a mini-game and Gaddget.

The Bob-omb Mafia supposedly protects Shroom City, but doesn't do anything during the duration of the game.
