Thanks kitten! - in hindsight his arms remind me of spastic water hoses spraying all over the place but then get reeled back in all under control. They make me think of playing in the water in the summer as a kid. Sonic arms --> water hoses --> summer memories. Weird. Ha!
I now have a mental image of those sprinkler toys that hook up to a water hose and splash water everywhere via flailing tubes, but with your version of Sonic and his arms are flailing water everywhere. Now I wish such a toy existed so that I may purchase it for my future children (which is a lie because I will probably play with it more than they will and happily be the most embarrassing mom).
