With all due respect, why not think about some “traditional” more manual approaches to animation. Create water-droplets and keyframe them. It will take longer but may be well worth the effort and experience. Who knows, it may be the next “new” look.
A little “mesh warp” might be fun. (Don’t forget the traditional principles of animation)
What it won’t look like is a “plug-in”.
Just a thought. Happy Holidays!
