Mini Boos are an item in Mario Super Sluggers. These Boos make the ball invisible so the player in the outfield can't see the ball. The Mini Boos are found in Wario City and are required for King Boo to join the player's team in challenge mode. Mini Boos may be a Boo that spit into many Boos to make the item like Boolossus in Luigi's Mansion.
