This is Jeff, the first creature I created in Spore. I'm mostly doing this to see how easy it is to capture video from the game and embed it in the blog. The answer is something like three clicks. They did a great job with the YouTube integration.
I didn't play around much, besides creating this seven-legged beast. I had no idea how he was going to walk with a single, ten-foot long hind leg with a knee above his head. But that was for the game to figure out. So far, this is pretty fun.
