Boo Repellent is an item that appeared in Mario Party 3.


For 10 coins, a player can purchase the item at Toad's Shop, win it in an Item Mini-Game, receive it for answering Toad's question, or receive it via an Item Bag. If a player is in possession of this item and another player sends Boo to steal something, the item will activate automatically, spraying a weird gas on Boo which causes him to be unable to steal that players stars or coins.
