Can't make venom tentacles effect

[Andy Reyand]

Hey everyone!) I'm learning tyflow and I have a scene where a cube explodes into weird little pieces thanks to voronoi and a hurricane.  the scene is in slow motion, and pieces of the cube are hanging in the air after the explosion.  I made it so that splines were created from the center of the lip, which, like a web, stretched to each of the debris.  how to make these splines look like tentacles like a symbiont in venom.  I had an idea with the help of phoenix fd, but it didn’t work out for me there, I don’t know him well either ..

The picture shows a cube and splines, instead of which I want to make it look like tentacles

I'm quite new. Thank you
