Sorry that this is late or was already made, but I just saw a new game for Avatar at Nick, featuring Toph. Yes, its about time she got her own game. Anyway, as Toph, you have to get the gaang safely across Serpent's Pass. Repair the stone pathway and avoid the serpent as Toph and use Aang to prevent your friends from falling into the water. If the guys get too scared, they'll run away.
I tried playing just now, but for some reason, the controls didn't work... again. This happens for too me with Nick alot.
