I have the Crab backpack. That's all well and good but I wish I could change the color. Also: A: I can't seem to find the Crab Armor selections. Its not under Armored or special uppers or anything. Are we supposed to be able to wear the rest of the Crab armor? B. I have found the crab helmet but it doesn't change colors like the Widow helmet? I currently have a level 27 Crab. I don't know if you have to get to lvl 30 or 50 or something to unlock it.
