Stretchy Tenticle

I’ve been tryin to figure out how to make a tenticle that not only can wrap around effectivly, but stretch as well. However, I can’t seem to keep the rig stable. Making IK for easy moving wasn’t to bad. I could make the tenticles stretch, but combining them made it pretty much explode and fling all over. Any sugestion how to stabalize and make it work?

Dont know if this helps but here’s my take on a stretchy tentacle type thing. If I remember right I found this tut on blender.org about rigging a snake.

Thanks alot, this was exactly what I was lookin for! Though curious if you need those empties or not? The rope tut on Blender.org just stuck it right onto the bones directly.
