I picked up mine from roktsintst. If he's reading (doubt it he's out of the hobby) maybe he can chime in as to the origin of the colony. By the time I heard he was breaking down, he had already fragged up and sold the entire colony. I bought the remaining encrustment. Until very recently it's pretty much just continued to encrust. Mine has a lot of the green color in the base like nuocmam's...maybe slightly more of a yellowish green though.
