Sonic the Hedgehog (16-bit)/Development

Evilhamwizard - I'm going to regret bringing this up, but those MBZ "UFO"s don't look like UFOS. They look more like planets than they do UFOs. I know it wouldn't make sense saying their planets (yeah, a bunch of planets all over the place, bawww) but as you can see here: http://www.sonic-cult.org/dispart.php?catid=1&gameid=1&subid=4&artid=9, they don't move from side to side, they remain stationary. It also wouldn't make sense for UFOs to have a ring around them in motion (what UFO does that?). Also looking at the sprites a lot closer, a spot of blue can be seen between the ring and that sphere it's going around (http://www.sonic-cult.org/dispart.php?catid=1&gameid=1&subid=4&artid=4 See the second picture). This is going to sound really retarded, but can we refer to them as "planets"? More and more, I see no reason for them to be called UFOs, since they do nothing that stands out for sure that it's a UFO. Kill me. :(
