I Think the part about 2 keys makes great sence, because in the 3.0 version, at the end of the feral rock canyon where you climb the rocks and walk onto the bridge to ecape the feral rocks, you can go through a slime key door. It has no special name, but it is home to a cat gordo, which will give you a key. then there is a honey gordo in the second area of the moss blanket, and a rad gordo in a cave of the indigo quarry. assuming you have already aquired slime keys from both the phospher gordo and pink gordo, that makes 5 keys and 3 unlockable areas. So with all 3.0 areas unlocked, you should have 2 keys left over.
