Bonus Stars are Stars that are given out at the end of a Battle Royal in each mainstream Mario Party game. They are last-minute bonuses given to players (or teams) who've excelled in a particular field of gameplay during the game itself. So to say, the player who appears to be in first place at the end of the final turn may ultimately lose if an opponent receives enough Bonus Stars to surpass them. In Mario Party 8, the Bonus Stars can be turned on/off in the Party Tent Menu. After gameplay, MC Ballyhoo gives out the Bonus Stars.
