Grab Bag (item)
From the Super Mario Wiki
A Grab Bag is a very rare item that costs 25 coins in Mario Party DS. It can be found during the last turns of a 20, 25 or 30-turn game or can be found in an item block. When a player uses it, it takes away all their items, but gives them a Star Pipe, Block Sensor and Triple Dice Set, similar to an Item Bag in Mario Party 3 and Mario Party 4, but it has only three specified items, unlike an item bag, which contains three random items.
