Well, since the piece is called Green Tea, and tea generally comes from plants, I thought the plantlike tentacles looked fitting. That's actually why I liked the branching in the original tentacles...it was rootlike. It looked like it could be some kind of bulb-creature that would dwell in the topsoil, looking around with its bulbous eyes. A raccoon would wander a little too close and then it'd pop outta the ground and strangle the raccoon before allowing it's acidic cloud to dissolve the carcass enough to be digested.
...or something like that.
