On problem with the Tube tool is that it maps the total length of all tubes in the figurine on the height of the normal & diffuse map. Because of the many long tentacles that only leaves a very small fraction of these maps for the main body, with a low resolution (e.g. of the eye) as a consequence. It really should have mapped all tentacles just once on the height, putting them side by side, as their circumference is very small. So they don't need much width in the maps. (I guess in fact they could all share the same part of the map.) It seems a bit hard to do that automatically. (Although for structures that get duplicated I could assign them each the half with of the map, instead of the full width, and putting them at different height.) So I suppose I must craete some input instruction to tell it a tube has to use the same map area (at least vertically) as the previous one.
This is my stab at the Octopus:
