Grab Bag

Grab Bag first appears in Mario Party as a 4-Player mini-game. In the sequel, it is only playable in Party Mode as a Battle Mini-Game. It involves players pressing the B Button to grab other players' bags and steal their coins (in Mario Party) or mushrooms (in Mario Party 2). The player with the most is the winner.
