I like the idea, maybe it has some glitterworld substance/artificial microbes that block the digestion of it (invented to allow feasts without getting fat? Also the microbes could buff the health/immunity gain speed), thus preserving it.
Also if animals get into play (licking the tasty rock, predators preferring those areas) it makes it more interesting and adds a risk vs reward (manhunter animals [my food!], predators to bypass)
