Need help for a particular effect on a mesh...

Hi all !

Im looking to achieve a special effect, I have a animated tentacle mesh with classic bones chain, and I need to attach via bone socket a particle emitter to have an effect like this :

In fact, I need to create (via particles ?) such an effect, where simple geometrical shapes (boxes, spheres and triangles) move (and rotate) along the mesh surface…

Here is an Artwork :

The effect must begin from the base of the tentacle to the end.

I hope someonr will be able to help me with that !

Thank for your time.

****, as always no response… I must be cursed !!

Thank you anyway.

You can quite easily spawn particles from mesh surface but making them to follow mesh surface might be tricky part.
