Rigging A Jellyfish

I am a senior in college studying game art and animation. I have a year long project that I have to get done and it's focused around technical art. Right now, I am making a jellyfish rig that I want to be game ready. I already have the tentacles and the dome of the jellyfish rigged and now I am thinking about ways to make the jellyfish easier to animate for an animator, like automating the rig to do certain things. One thing that I came up with and did was a rippling motion on the tentacles, but I can't come up with any other things to automate for an animator. Any thoughts on what I can do?
