Coral? Just how many retextures of this item exist O_o
Hopefully loads

I've found Golden (obviously), Ivory and Sapphire so far, and used (then re-sold) them all. I also found a switch that required an Emerald Claw, but I haven't found that one yet. I'm guessing there will be Ebony, Ruby and Silver, plus maybe Topaz, Amethyst, Aquamarine, Diamond...
God I love this game. Endless enjoyment.
