What I think would separate it more from the Cycloptus is if you made the one slime thing it has spin around all the time. That would be kind of cool.
When the Gyro is attacking, the center thingy will open. I don't think it would be very realistic if slime spewed out of the center if it doesn't fire a projectile.
Magic done! Now there shall be spinning of the slime thing... File:http://www.mediafire.com/?9zzjze1efjy
