I just got a few more emeralds :) All my characters have 3. I have issues getting emeralds as knuckles, though. Has ne1 else notice his up R attack sucks? He gains hardly any height, and after the move is up, he can hardly move to the side. Plus, his glide is very bad. Oh, and I'm going for Music Plant next: Any advice for the special stage? I had all 7 special rings, but I fell to my death.
Edit: K, I need no more advice, I have that emerald now.
