Waving Tentacle?

I’ve searched and searched and can’t find much at all. Any ideas on the following:

I’m wanting to animate a cartoonish squid. The only frame by frame and/or tweening animation I care to do is for the head, face and two tentacles (his gesturing “arms”)… for the rest of the tentacles (8) I’d like to have them just waving as if he’s treading water. Just a basic (but somewhat smooth) wave looped within each tentacle mc. I don’t care if it’s tweened, frame by frame or actionscript driven (it’s not for video output)… Anyway, I’m having a heck of a time finding any decent examples of a good “waving tentacle” and all my attempts at making it myself have been crap (too stiff, outline getting broken, etc.) Any ideas or examples out there on how to best achieve this?

Thanks in advance!
