Hehe, that was completely my reaction as well ^^
Actually, I have no idea how he does it, but I'm sure it can't be done through XSE. I'm just gonna tell him what I want done, when I want it done, and he'll do it :P I'm sure I could get him to do something similar for you ^^ Like I said, he's amazing with that sort of thing. He's not completely done it yet, he's still hacking the bike and surfing sprites, but once he's done there, I'll try and get him to help you out with it, yeah? Glad to be of service *salutes*
