The Boo Bell is an item that appears in Mario Party 2 (and goes on to appear in Mario Party 3). It rarely appears and can only be obtained in an Item Minigame. Its use is to ring for Boo and ask him to steal coins or a star, depending on how much the player can afford. In Mario Party 3, it appears more frequently, and can be purchased from Koopa Kid.
The Boo Bell was replaced by Boo's Crystal Ball in Mario Party 4.

- The Boo Bell may reference the medieval practice of burying the dead with a bell on a string tied to them (the bell being kept above-ground), so that if someone was buried alive, they could ring the bell so the grave keeper could dig them out.
