Deep sea algae model request

[Remixer]

So I am working on my project Beneath the Surface and I need an tree model that fits underground. I was thinking of some kind of deep sea algae.

So the model should have animations like trees (and if you just can
maybe swinging animation also) (like in the wind).

Here is some links to get idea how it could look:

So ask for more information and say if you can make it

So:
1. Same animations as trees ( bonus if swinging )
2. Size they can be single or be in a bunch
3. I would prefer ingame textures but if you have very good looking custom it will do also.
4. Similar to the algae in the picks.
