Boo Repellent

From the Super Mario Wiki

Boo Repellent is an item found solely in the game Mario Party 3. It has a similar effect to Mario Party 4's Gaddlight.

When Boo tries to steal coins or a Star from a player holding a Boo Repellent, the item automatically activates, spraying weird gas at Boo, causing him to flee. Boo Repellent can only be used once. It is also possible for a player to throw away a Boo Repellent at the start of their turn, should they wish to clear room in their inventory, although it counts as using an item for that turn.
