Dry Bones is an enemy mostly encountered in towers, castles, or ships. They act as Red Koopa Troopas, turning around when reaching the edge of a platform.
Unlike it's younger brother Koopa Troopa, Dry Bones cannot be defeated easily. Dry Bones will collapse when stepped on, but will be revived after several seconds. They are immune to Fire Flowers, but they can be permanently destroyed by rarer items such as Super Stars. The Big Dry Bones will be stunned for a very short time when stepped on, but can only be collapsed with a ground pound. Adding wings to a Dry Bones will turn him into a Parabones.
- When a Dry Bones is placed in the underwater course theme, a Fish Bones will be made.
