Tentacles Curve Wave Effect Anyone have any ideas on how to animate curves to perform like a wave effect instead of this side to side animation I did?

Took me a while to find an example but found one by James Curran:
You can use the wave modifier and press play animation.

In my example I rotated my object by 90 degrees without applying the rotation, so to have the desired effect.

Make sure to have enough geometry in your mesh, with evenly distribuited quads.
