Well, if you like the silicone-feel of the Ocean and want to try the rotation as well, I'd say to check out their Paul and Paulina. However, there seem to be people that say that there isn't enough power. There is a video on the Paul and Paulina that shows the rotation of the toy though, so you can look at that to see the strength. Otherwise, if you want the body-safe silicone as well as some stronger rotations (with some better reviews), I recommend one of the L'Amour Premium Massagers. They all rotate and come in different rotating shaft shapes. They come in blue, purple, and pink, and here are the links:
, Thumper (Purple)
, Flutter (Blue)
Along with that, here's the link to all body-safe silicone rabbit vibes:
Keep asking questions if you still have them. I'm not a rabbit vibe expert, but I'll help where I can.
