Boltbulb

A biometal vegetable edible by any species, but only grown by the glitch. This is not metal-plated food, but solid metal, even though it's soft and edible. The vegetable is harvested from the ground and new seeds need to be planted afterward.
When the unnamed robot claimed Daenc Hydrax 4 as its planet to govern, the glitch civilization there had this already growing at their farm.
