Wisp
caolositric
The Wisp is an enemy which is similar to the Blue Bubble; it will jinx Link if it touches him, however it is non-agressive and will simply float around.
Quote from The Legend of Zelda: The Minish Cap Wisp figurine:
"Appear in dungeons. They float in midair. They won't hurt you if you touch them, you won't be able to use your sword for a while."
