Parabones

Parabones are winged sub-species of Dry Bones that first appear in Super Mario 3D World, replacing normal Dry Bones.

Parabones fly a small distance above the ground and attack the player if they notice. Like normal Dry Bones, if a Parabones is attacked without the use of a Star, Lucky Bell, or Invincibility Leaf, it will collapse temporarily, but reassemble itself after a short time. During its reassembly, it is vulnerable to getting attacked. A Parabones can also be permanently destroyed if it collapses over lava or a pit. Unlike their counterparts, the Koopa Paratroopas, their wings also reassemble after they get hit, like their other counterparts, the Dry Bones.

Trivia

 * Parabones are the only flying sub-species of Koopa Troopa to appear in a 3D platformer, even before the standard Paratroopa.
