It is a little known fact that one side effect of becoming a Nurgle Rotter is that one's flesh tends to loose its structural integrity. Before you know it there is nothing very much keeping your insides inside and your bones and larger organs start falling out all over the place. Most Rotters tend to pick up discarded parts and jam them roughly back into place but this is mainly for cosmetic reasons as the Choatic Forces that come along with Nurgle's Rot are quite capable of holding the rotting remains of a body together without any other structural support.

For several months Coach Nigglefish has had his under-cover cronies following the Pocketful of Posies Rotter, Armageddon, around, collecting any bones that happen come loose. Each henchman is given instructions to follow the Rotter in the shadows, wait until something drops, sneak forward and grab the discarded body part, run as fast as they can back to the laboratory, wash their hands and report to Nigglefish with the collected bone. The bit about washing their hands is underlined.
