Spirit Balls are enemies that appear only in Luigi's Mansion: Dark Moon.
Spirit Balls are small in size that are clear in color. Spirit Balls are found in every mansion and they are created by Boos. Spirit Balls mainly hide in certain objects making them invisible. Luigi can reveal them using the Dark-Light Device and vacuum them all up into the Poltergust 5000. Luigi must be quick because if he doesn't vacuum them all up in time, they will go back into the object and must be vacuumed up again. Spirit Balls can hurt Luigi by simply touching him.
