Grab Bag first appears in Mario Party as a 4-player mini-game, and Mario Party 2 as a battle mini-game. The name of the mini-game is a play on words of "grab bag" which is a term used when someone wins a bag filled with stuff.
In both games, 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). In the original game, what the players' coin totals are at the end of the minigame will determine what they will possess on the board game. In Mario Party 2, each player starts with 5 mushrooms, and one player has a Golden Mushroom worth 3 points, and the player with the most at the end of the time limit is the winner.
In Mini-Game Island in the original game, the player starts with no coins while each CPU has 20, and the player must earn 15 coins to clear the game. As this is a Battle Minigame in Mario Party 2, this minigame is not present in the Mini-Game Coaster.
