Animate tentacles so that they appear from a single point before extending to their full length?

I used paths to give an idea of their trajectory, but I don’t think the “follow path” constraint would be the best option, since I want these tentacles to be dynamic. I guess the best way would be to use bones, but I don’t know what to search for to find a corresponding tutorial…

Btw, no, it’s not for X content lol. However, I must admit that I’m inspired by Giger’s creations

Use geometry node trim curve to animate length and curve to mesh to give thickness

Thank you!!
