I made this one of Otto (I think that was his name in Saira, not sure if that has always been the correct name) a few months ago. It was supposed to only be revealed during gameplay of an upcoming level of mine, but as it seems I get busier every day, I don't think I'm going to finish it any time soon. It may feel weird to control such a bulky chathiracter in KS, but I think it's not too bad. I recommend not using the umbrella, it probably just covers his face or something.
You are free to use it as you please, but I'd really like to be notified via PM if you do so.
