Haley is a regular enemy appearing in Kirby & The Amazing Mirror. He resembles a small hedgehog with glowing blue quills that appear to be ablaze (which is probably a reference to a certain blue hedgehog.) Haley simply soars through the sky in a line and has no other means of attack. He gives no ability.
