Bowser Suit

The Bowser Suit is a somewhat rare item that first appeared in Mario Party 2. When used, the character who used it will wear a Bowser-like costume and be able to take twenty coins from every opponents he or she passes during their roll. Baby Bowser may even give a character dressed in a Bowser Suit coins as well.

In Mario Party 3, Bowser Suits could sometimes be purchased from Baby Bowser at the Item Shops.

In Mario Party 4, players could only accuire a Bowser Suit by landing on a Bowser Space and even then, the chances of getting one would be slim to none. Waluigi was even pictured holding it on the box art of Mario Party 4. Strangely, in that game it strongly resembles a Mushroom.
