Ok this is the problem! I have tried using the Warp but I came just a headache …
figuring out how to move the snake without breaking the nose of the same lineage around doing so many different pieces of body encapsulating, I resolved that when I first motion by the leaders hope that will not change shape and then all the objects which I do not imppossibile … then say:
In synfig missing important bones (as in Blender 3D, and although still vector) which can extrude and that can monitor individual objects such as circles or other shapes and leaders and selected individuals, if only those of the head (using blender create a group leaders do not know if it’s useful info) and then move only those objects and those vertices perhaps encapsulated the bones could well turn also lengthen and shorten!
