Aracha

The Aracha are small, one-eyed infantile Moldarachs found in the Lanayru Mining Facility in Skyward Sword. Aracha who have lived for a millenium grow into Moldarachs. They act similarly to Tektites from other games. They are arguably the easiest enemy in the game, as they take one sword slash to defeat, and they do less damage than a Keese.

Characteristics
Aracha are found on floors of caves and dungeons, in piles of dust or sand, and clinging to climbable walls much like the Skullwalltula. They will leap at Link, or crawl onto him if he encounters them on a wall, and attack while clinging to him until they are thrown off. They can be easily killed with a swipe of the sword or with any projectile, including Slingshot pellets. One gust of the Gust Bellows will knock them over and away from Link, although they right themselves quickly.
