I haven't played Roblox before so maybe I'm missing something obvious with it, how do you get the Sonic/Tails/Knuckles avatar/skins? So far all I seem to be able to do is run around with the generic avatar collecting diamond things and leveling up the speed. I've tried traveling to "Green Hill Obby 1" but can't seem to click it in. Dunno what's going on. I'm playing on Xbox One if that makes a difference, if anyone happens to know what's up.
