Dry Bones

Dry Bones (カロン, Karon also known as Skeleton Koopas) are a fictional species of undead koopa in Nintendo's Mario series of video games. They are skeleton versions of Koopa Troopas.

Dry Bones are the skeletal remains of Koopa Troopas that have been re-animated. When jumped on, a Dry Bones will fall apart. However, a collapsed Dry Bones will eventually reassemble itself to its original form. However, they can be defeated with certain special attacks (such as with the Cape Feather, Hammer Bros. Suit or Starman). Dry Bones usually prefer dark places, mainly castles, but have been known to live in other areas like the desert or sunken ships.
