Rib
Ribs are classed as flat bones which usually have a protective role in the body. Humans have 24 ribs, in 12 pairs. All are attached at the back to the thoracic vertebrae, and are numbered from 1–12 according to the vertebrae they attach to. The first rib is attached to thoracic vertebra 1 (T1). At the front of the body most of the ribs are joined by costal cartilages to the sternum. The ribs connect to the vertebrae with two joints, the costovertebral joints.
Cubivore: Survival of the Fittest
Less essential than mutations are limbs. Limbs are lost when torn off in combat, resulting in a mutation of whatever has torn off the appendage. A Cubivore with missing limbs can regain them by eating limbs from other Cubivores. Every generation of a Cubivore will have one more limb than its parent generation. Each limb can hold one color, one Raw Meat, and allows the Cubivore to attack stronger enemies. For example, a Cubivore with one limb can attack one with up to two limbs, while a Cubivore with two limbs can attack one with up to three limbs.
