Boo's Crystal Ball

Boo's Crystal Ball is an item featured in Mario Party 4. A player could use the item to summon a Boo to steal Coins or a Star from an opponent.A Boo's Crystal Ball can be purchased at item shops or won in Mini Minigames. The only reason why it replaced the Boo Bell from older Mario Party games is because it shows players their opponent getting robbed by the Boo. The player can stop the Boo from stealing a lot of coins by merely taping A rapidly, but their coins would still get stolen from the Boo.
