Usually movement depends on how far the skeleton mutation has taken over the Jolles body. Those afflicted by the skeleton mutation have hidden their organs in an easily camouflaged casing for protection but ALL JRs have a special core that keeps all the bones gravitated to the body so their bones and things don’t drift away - especially in the cases of skeleton JRs. (a low form of magic but nothing else can be done with it, yet...)

 

Given the fact that skeleton mutation cannot affect much parts of the body commonly, there are special cases which occur and most often have a different composition compared to those with smaller afflictions. The issues that can come forth on those with smaller afflictions of one limb or part (arms, exposed spine, skull, ribs) is that the composition is less likely to be stronger than larger afflicted species and so against the elements and other environmental issues, they must consume a very high calcified diet in order to keep their bones strong.

​

Issues a smaller afflicted skeleton mutated JR may have include:

- Brittle bones

- Can easily damage exposed bones from even minor falls (paws and ribs are more likely to break if affected by skeleton mutation)

- Bodily injuries (usually from first time attempts at walking and things after evolving from baby to adult)

- Limited movement in colder climates - however subtypes such as tundras may find it easier due to them having a better reaction in colder weather.
