I'VE GOT IT!!!!! Copy Sonic.plr to Sonic.wad, (don't rename), then open XWE. Change the name of "sonic" to "tails". Then, open the console, and type in ADDFILE sonic.wad SKIN tails. Then, you can run on water. It should work! I used XWE to make tail's speed to Sonic's speed, and he can run on water without sneakers! That is like, so totally Dude-ish!!!
