Haley is an enemy exclusive toKirby & The Amazing Mirror. It resembles aporcupine orhedgehog with peach-colored skin, blue eyes and a coat of blue spines trailing behind it like fire. It possesses no visible mouth or limbs.
Throughout the game, Haleys are primarily encountered at high altitudes. To attack, these simple opponents do nothing but fly leftwards or rightwards in a straight line, depending onKirby's position in relation to their own at the moment they appear on the screen; once in Kirby's view, they cannot turn around anymore. Colliding with a Haley causes Kirby to lose health and knocks the enemy back a little, but does not keep it from proceeding on its path. Despite its primary role as an aerial creature, Haley is also capable of surviving underwater.
While Haleys are vulnerable to any attack, inhaling and swallowing them does not grant Kirby aCopy Ability. Its name appears to be based afterHalley's Comet; a fitting name given its comet-like appearance and its common sightings in outer-space regions.
Haley is also probably a reference to Sonic from theSonic the Hedgehog series, having a pointy face and blue spiky spines that bear a close resemblance to Sonic's own physical features.
