JellHead Powerstructure

JellHead
The Skeleton of a JellHead, made of energy

Ever seen JellHeads with any skeletal structure or bones?
No?
No wonder!
JellHeads only consist of Jell in their inner body!
 
But how do they still stand, walk and move around without wiggling around or breaking down, if they don't have the support of bones or joints to do so?
 
Instead of a visibile skeleton, they have an (for the normal eye) invisible power structure in place of the old skeleton.
Since the head is not needed, the structure for the head part is always missing.
 
The Power structure enables the JellHead to move around like it's host species.
But since the structure is made out of its own energy, it will lose stability if weakened or tired and may collapse until energy has been replenished.
 
Some Jellheads with special perks have additional power structures, for example attached to their functional JellLimbs to move these around.
It's not to be mixed up with the artificial "JellLimbs" mutation.
We don't know how to create additional power structures to give artificial JellHeads functional JellLimbs .
