Sky Tails are enemies from The Legend of Zelda: Skyward Sword. They are flying worm-like creatures that inhabit the Thunderhead. Sky Tails travel in groups and attack Link by dive-bombing him while he is riding the Crimson Loftwing. Their tails act as weak points and they are vulnerable to Spiral Charges from the Crimson Loftwing. Sky Tails are somewhat similar in appearance to Moldorms, as they both have orange bulges on their tails. Even before obtaining the Spiral Charge, it is possible to kill them with the Crimson Loftwing's normal charge.
