Wisps are enemies that appear in The Minish Cap.
The Minish Cap
Wisps come in two varieties, red and blue. If one comes into contact with Link, he will become Cursed and won't be able to use his sword for a period of time. These enemies can easily be disposed of by using a Boomerang or the Bow.
|Appears in dungeons. They float midair. They won't hurt you, but if you touch, they won't be able to use your sword for a while.|
