Characteristics and Variations

Unlike Sparks, their movement is slightly unpredictable, as they change directions randomly whenever they hit an object. Winders have identical behavior in and, although in these appearances they can set fire to Link, making them very dangerous when combined with other enemies or traps. In The Minish Cap, they can be found in the Temple of Droplets, the Palace of Winds, and Dark Hyrule Castle.

In both and, Winders are electrically charged and travel solely along walls. Simply touching one will shock and hurt Link. In Spirit Tracks, they are named "Moldola". Moldola are actually helpful against Heatoises, as they are weak against electricity.

Strategy
Winders are usually invincible, therefore it is best to avoid them entirely. However, in Spirit Tracks, they can be defeated by firing an arrow at the "head" of the being (the largest ball of energy).
