Houdini wires with a few field forces, one for noise (4D anti-aliased), one for general attraction to the target object (bunny), a stronger attractor force with a larger search radius just for the tips of each tentacle.
Rendered with Mantra PBR.
* Tweak the strength of the tip attraction force so it's not so strong when it's right next to the target object.
* Setup alignment normals along the wire, get the attractor forces to align towards the target object.
Integrate this into a procedural modeling solution that builds tentacle suckers aligned with the normals.
